Patrinia villosa Juss often grows in roadsides, grassy areas, thickets, forest margins or forests, with an altitude of 100–2000 m. It is a perennial herb with a height of 50–120 cm. Its rhizomes are long and laterally, rarely stoloniferous. The stems are yellowish green with anatropous white coarse hairs, rarely uniformly glabrous or glabrescent. The basal leaves are rosulate, long petiolate, ovate, broadly ovate, or oblong-lanceolate to ovate-lanceolate and with an area of 4–25 (l.) × 2–18 (w.) cm; the base of its leaf is decurrent and margin serrate or pinnatifid, with 1 or 2(-4) pairs of segments, apex acuminate. The coarsely serrate cauline leaves are opposite, petiole 1–3 cm, upper leaves subsessile; it is bright green or dark green on the upper surface, white-green on the underside, and the blades are similar to basal leaves or rhombic-ovate, hispidulous or glabrescent, base decurrent, apex caudate-acuminate or acuminate. White terminal panicles or umbellifers are composed of cymes; lateral branches are usually 5 or 6 pairs, densely hirsute. The corolla is campanulate; the tube is 1.5–2.6 (l.) × 1.7–2.3 (w.) mm, deeply 5-lobed; its lobes are dissimilar in shape, ovate, ovate-oblong, or ovate-elliptic, 0.7–2 (l.) × 1.1–1.8 (w.) mm. The 4 stamens of the plant are usually exserted from the corolla. Achenes are obovoid; the flowering of PV occurs from August to October whereas fruiting occurs from September to November ( Fig. 1 A) ( Flora of China Editorial Committee, 1986 ). Patrinia scabiosaefolia Fisch generally grows in roadsides, grassy areas, thickets, forest margins, and forests at an altitude of (50-) 400–2100 (−2600) m.

Comprehensive consideration of the pharmacological activities, the prescription containing Herba Patrniae in Chinese patent is mainly used to treat gynecological diseases, such as chronic PID ( Dai et al., 2019 ; Deng, 2019 ; He et al., 2019a , 2019c ; Hou, 2019 ; Lu, 2019 ; Luo, 2019a ; Lv et al., 2019 ; Zou et al., 2019 ), vaginitis ( Jiang, 2019b ; Li and Li, 2019a ; Long, 2019 ; Luo, 2019b ; Nong et al., 2019 ), cervicitis ( Li, 2019a ; Zhang and Jiang, 2019 ), and breast disease ( Gao, 2019c ; Wu, 2019 ; Yan, 2019a ; Zhang, 2019a ); urinary system diseases, such as prostatitis ( Li, 2019c ; Long and Yin, 2019 ) and orchitis ( Yuan, 2019 ); respiratory diseases, such as chronic laryngitis ( Gao, 2019d ), rhinitis ( Gong, 2019 ), and bronchitis ( Zhao, 2019 ); digestive diseases, such as gastritis ( Li, 2019d ; Xiong, 2020 ), hepatitis ( Feng, 2019 ; Jiang et al, 2019 ; Liu, 2019b ; Ru, 2019 ; Zhao 2019b ), pancreatitis ( Dang et al., 2019 ; Li, 2019e ), appendicitis ( Zeng, 2019 ; Zhang, 2019c ), colitis and proctitis ( Chen et al., 2019d ); skin diseases, such as shingles ( Dong, 2019 ), wound infection ( Jiang, 2019c ; Tan, 2019 ; Yu, 2019 ), and tinea pedis ( Gao, 2019f ); and animal inflammatory diseases, such as infectious bronchitis and fallopian tube injury in chickens ( Zhang et al., 2019b ), and animal mastitis ( Zhou et al., 2019 ). Besides, in hygiene, it can be used to prepare oral care liquid ( Peng et al., 2019b ; Ye et al., 2019 ), laundry liquid ( Xie, 2019 ), and toilet paper ( Zhang, 2019f ). Other patented products containing Herba Patriniae include an anti-cancer decoction for lung cancer ( Wang, 2019a ; Wang et al., 2019b ) and nasopharyngeal carcinoma ( Xie and Xie, 2019b ), a cosmetic for antioxidation ( Wu, 2017b ), anti-aging ( Chen et al., 2018 ), acne ( Ou, 2018 ), whitens ( Geng et al., 2012 ; Li, 2018a , 2018b ), and dark circles ( Wang et al., 2018 ).

An effective quality control method plays a key role in drug safety and effectiveness. With development of technology, UV, HPLC, and GC-MS have been used for monitor the variety of components in Herba Patriniae ( Table 6 ). The content of total flavonoids has been quantified by UV method. It is worth concerning that the contents of total flavonoids were great difference in different parts, for example, 47.9–57.4 mg/g in leaves, while 18.1–29.2 mg/g in stems ( Xu and Zhou, 2004 ). The extraction solvent also has great influence on the content of total flavonoids. Sun et al. found that the content of total flavonoids in PV extract by water was higher than that by 70% ethanol (334.00 ± 5.20 mg/g v.s. 293.00 ± 2.65 mg/g) ( Sun et al., 2018 ). This phenomenon also occurs in the extraction of organic acids, such as chlorogenic acid and caffeic acid ( Sun et al., 2018 ). These results indicate that flavonoids and organic acids are more easily extracted by aqueous solution. Table 6 Quantitative analysis for the quality control of Herba Patriniae.

( PS ). Not indicate species. Up to now, nineteen compounds, including quercetin, kaempferol, isovitexin, isoorientin, ursolic acid, oleanolic acid, hederagenin, chlorogenic acid, caffeic acid, iso-chlorogenic acid A, iso-chlorogenic acid C, protocatechuic acid, inositol, palmic acid, hexanoic acid, cis-anethol, camphogen, β-ionone, and β-damascenone, have been quantified in Herba Patriniae. The content of compouds showed significantly different in Herba Patriniae from different sources ( Chen, 2008 ; Liu et al., 2013a ; Liu and Lei, 2019 ; Mao et al., 2012 ). In addition, the same compounds showed significant different content in two species. For instance, the content of kaempferol was 0.082–0.701 mg/g in PV, while that was 0.045–0.542 mg/g in PS ( Liu et al., 2015 ). The chemical composition in herb is closely related to its pharmacological action. Therefore, the herb species, sources, and processing method should be fully considered in Herba Patriniae clinical use ( Liu et al., 2016c ; Zhang et al., 2011 ).

In traditional use, Herba Patriniae is almost non-toxic. However, mild side effects can be produced when large dosage is used. Excessive use of PV water extract can cause temporary leukopenia, dizziness, nausea and other symptoms ( Deng, 2001 ). According to the reported toxicity of PS , the methanol extract from the root of PS increased the serum aminotransferase and caused histopathological changes in mice ( Wang, 2009 ). In addition, when the oral dose of PS up to 200 mg/kg, it will lead to polyuria ( Wang, 2009 ). Gavage of 30 g/kg of PS alcohol extract in mice can cause mild diarrhea and mild respiratory depression, but there is no adverse reaction at the dose of 24 g/kg ( Wang and Sun, 1997 ). The volatile oil of PS was given 400, 750 and 1500 times as much as that of human (0.8 mg/kg) to mice for 7 days, that showed no abnormal performance ( Luo et al., 1986 ). In clinical application, individual patients suffered from dry mouth and stomach discomfort after taking PS , and it will disappear after stopping the medicine. Its volatile oil products have no side effects on liver and kidney function and leukocyte count ( Wang and Sun, 1997 ). Above all, Herba Patriniae is quite safe for animals and people at a reasonable dosage (see Table 5 ). Table 5 Toxicity of herba patriniae.

Herba Patriniae can be used in clinical treatment in the form of a single herb or compound formulae of TCM to treat diseases for more than 2000 years in China. So far, a total of 233 compounds have been identified from the two species of Herba Patriniae, including triterpenoid saponins, flavonoids, organic acids, iridoids, and volatiles. However, the two species applied as Herba Patriniae gave obviously different in phytochemistry. PS is rich in triterpenoid saponins and volatiles, while PV contains more flavonoids. Meanwhile, it's easy for us to see that the content of the same compounds (chlorogenic acid, caffeic acid, quercetin, kaempferol, palmic acid, hexanoic acid, cis-anethol, camphogen, β-ionone and β-damascenone) were different in two plants. Even within the same plant, the content of the compounds (protocatechuic acid, chlorogenic acid, caffeic acid, iso-chlorogenic acid A, iso-chlorogenic acid C, ursolic acid, oleanolic acid, isovitexin, isoorientin, hederagenin) were variable in different sources, indicating that the herb species, sources and processing method should be took into full consideration in its clinical use. And it is urgent to seek a feasible and reliable standardized sample processing method for Herba Patriniae. The pharmacological studies of Herba Patriniae in vivo , in vitro , and in clinic were summarized. Two source plants of Herba Patriniae gave similar pharmacological effects, including anti-cancer, anti-inflammatory, antioxidant, antimicrobial, sedative, and hypnotic effects. These functions are closely related to the SIRT-1, mTOR, AKT, mir-144-3p/Nrf2, FAK, PI3K/Akt, EMT and NF-κB signaling pathways. But there are no reports on antipruritic, proangiogenic, and anti-diarrheal effects for PS , and there are no studies on anti-diabetic effects for PV . This difference in pharmacological activities possibly related to the differences in the phytochemistry. So the interrelationship between compounds and pharmacological activities should be further studied. As the dose increases up to 20 mg/kg in mice, mild side effects were found. While the dose that causes the side effects in human was up to 4–12 g/day, and there are individual differences. Pharmacokinetics can provide scientific explanations for pharmacological and toxicological findings. Unfortunately, the pharmacokinetics of Herba Patriniae was lack, thus a range of pharmacokinetic studies on its active compounds are needed to provide comprehensive data for clinical application. Based on this review, the research on the dosage form of Herba Patriniae is not in-depth, so strengthening the work in this area will help to promote the development and utilization of Herba Patriniae. Altogether, this review extensively summarized the traditional uses, botanical description, phytochemistry, pharmacology, and quality control of Herba Patriniae, and provided information on the similarities and differences between the two plants for their further research and clinical applications.

Herba Patriniae has a wide geographical distribution, mainly in East Asia and North America ( He et al., 2017 ). Some plants, such as Sonchus Arvensis L., Sonchus Asper Vill, Sonchus oleraceus L. etc , may be confused as Herba Patriniae ( Lu, 1996 ), and hence, these adulterants of Herba Patriniae should be exclude when clinical use. Traditionally, according to records of “Shen Nong's Herbal Classic” (神农本草经), “Compendium of Materia Medica” (本草纲目), and “Synopsis of the Golden Chamber” (金匮要略), “Tai Ping Sheng Hui Fang” (太平圣惠方), “Pu Ji Fang” (普济方), “Sheng Ji Zong Lu” (圣济总录), “Qian Jin Yi Fang” (千金翼方) and “Qian Jin Fang” (千金方), ancient doctors have used the whole herbs and roots of Herba Patriniae for disease treatment, such as the stomach, intestine, liver, gallbladder, and gynecological diseases ( Tian and Tian, 2003 ; Zhu and Jiang, 2015 ). Herba Patriniae was recorded in Chinese Pharmacopoeia (1977 edition) for the treatments of appendicitis, dysentery, enteritis, hepatitis, conjunctivitis, postpartum blood stasis abdominal pain, swollen welling-abscess, and clove sores ( Pharmacopoeia Committee of the Ministry of Health of P. R. China, 1978 ). In addition, Herba Patriniae is also recorded in the standards of traditional Chinese medicine in many provinces of China ( Table 1 ). In Miao nationality, Herba Patriniae is also called “Jia jiang le” and used to treat rheumatoid arthritis, colds, and diarrheal ( Qiu, 2005 ; Wang, 2002 ). In Dong medicine ( Lu, 1992 ), Yi medicine ( Drug Control Institute of Yunnan Chuxiong Health Bureau, 1983 ), and Dai medicine ( Shi, 1983 ), PS is called “Nyangt ngeec liongc bail jangl”, “She wei long”, and “Pa hong”, respectively. Its whole herb is used to treat infantile diarrhea, schizophrenia, and infantile tinea capitis, respectively. PS is also called “Ba gai bao” in Zhuang medicine, and its root is used to treat icteric hepatitis, furuncles, and snakebites ( Shi, 1983 ). PV is called “Bitter vegetable” by She nationality ( Biological Products Identification Institute of the Ministry of Health, 1990 ) and “Pao zi tong” by Tujia nationality ( Peng and Guan, 1994 ). Its whole herb can be used to treat appendicitis, intestinal febrile symptoms constipation, mammary abscess, blister carbuncle, and Qi stagnation. PV is also called “Ba gai lan” and “Hong pa” in Zhuang medicine ( Biological Products Identification Institute of the Ministry of Health, 1990 ) and Dai medicine ( Shi, 1983 ), respectively, and its root is used to treat jaundice hepatitis, furuncle, local ulceration caused by snake injury, and infantile convulsion. Moreover, in Korea, people usually use the roots or whole plants of PS as a traditional herbal medicine to treat appendicitis, inflammation, wound healing, edema, abscesses, endometritis, and abdominal pain after childbirth ( Kang et al., 1997 ; Yang et al., 2001 ).

In recent years, Herba Patriniae has been extensively applied in clinical practice in China, especially in gynecology, such as postpartum pain, mastitis, dysmenorrhea, and tubal obstructive infertility ( Liu, 2019a ). It is noteworthy that Herba Patriniae is one of the most important ingredients in many prescriptions of TCM which is effective in diarrhea ( He, 1991 ), acute hepatitis ( Song, 1987 ), pelvic inflammatory disease ( Zhang, 1997a ), typhoid fever, paratyphoid fever ( Sun, 2000 ), ulcerative colitis ( Liu, 2011 ), anal cryptitis ( Shi, 2012 ), pelvic endometriosis ( Yan and Qiu, 2013 ), acute pancreatitis ( He et al., 2019b ), itching ( Wang and Wang, 2002 ), gastroesophageal reflux disease, benign prostatic hyperplasia, rhinosinusitis, mumps, and phlebitis ( Kong and Zhao, 2008 ; Zhu and Jiang, 2015 ). A powder composed of Coicis Semen, Radix Aconiti Lateralis Preparata, and Herba Patriniae, is a classic prescription for treating intestinal carbuncle in the “Synopsis of the Golden Chamber”, which is clinically used to treat chronic appendicitis, chronic pelvic inflammatory disease, and chronic prostatitis ( Ji, 2006 ). In addition, a powder containing Herba Patriniae in the prescription is also used to treat sinusitis, acute purulent tonsillitis, and recurrent upper respiratory tract infection ( Qin and Diao, 2018 ; Zhu and Jiang, 2015 ). Moreover, it showed significant efficacy in the treatment of psoriasis vulgaris ( Yan et al., 2015 ), Keshan disease ( Scientific Research Cooperation Group of Herba Patriniae in Yan'an City for the Prevention and Control of Keshan Disease, 1979 ), and chronic pelvic inflammation ( Jia, 2010 ) in the form of tablets. In the Chinese Pharmacopoeia (2015 edition), there are 6 Chinese herbal medicine prescriptions containing Herba Patriniae, among which Kangfu Xiaoyan Shuan and Yifei Qinghua Gao are used to treat gynecological diseases and respiratory diseases, respectively, while Longqing Pian, Nankang Pian, Niaosaitong Pian and Qianliexin Jiaonang are used to treat genitourinary diseases ( State Pharmacopoeia Commission of P. R. China, 2015 ). A summary of the traditional and Traditional and clinical preparation of Herba Patriniae in China is given in Table 2 .

NMPA was cited from the website: http://www.nmpa.gov.cn/WS04/CL2042/ . The tender stems and leaves of Herba Patriniae are rich in nutrients, fresh in taste, and grow in the mountains without environmental pollution. It is a high-quality vegetable that urban and rural residents like to eat. PV tea is also abundant in Hubei Province and Fujian Province ( Jiang, 2019a ; Xu et al., 2018 ). Herba Patriniae is not only used in human health, but also in agriculture, fishery, and animal husbandry. Interplanting Herba Patriniae in the newly reclaimed tea garden can increase the natural vegetation and reduce soil erosion and surface runoff caused by rainstorm erosion in the rainy season ( Chen, 2001 ). The combination of Herba Patriniae and other medicinal plants can be used to treat poisoned wound of cattle by Agkistrodon acutus bitting, crawling bee disease, liver and skin diseases of turtle and fish, and postpartum abdominal pain in cattle ( Chen, 2006 ; Li, 2002 ; Shi, 2010 ; Zhao, 2003 ).

Herba Patriniae, as known as “Bai Jiang Cao” in Chinese, is a traditional Chinese medicine (TCM) originally recorded in “Shen Nong's Herbal Classic” as a “middle grade” medicinal material, which has been used for thousands years. Besides, Korean ancient pharmacopaea “Donguibogam” also record its medical value, and it has been used for more than 400 years in Korea ( Jeon et al., 2010 ). It possesses the TCM properties of pungent and bitter in flavor and slightly cold in nature, and has been classified to the stomach, large intestine, and liver meridians ( Xiao, 1995 ). Two official species of Patrinia scabiosaefolia Fisch. ( PS ) and Patrinia villosa Juss. ( PV ) ( Fig. 1 ) were considered as Herba Patriniae in Chinese Pharmacopoeia (1977 edition) and Chinese provincial pharmacopoeias. These two plants have been widely used for more than 2000 years with good biological activities of clearing heat and detoxification, eliminating carbuncle and expelling pus, dispelling blood stasis, and relieving pain. Through an analysis of ancient and modern literatures, Herba Patriniae was mostly used in intestinal carbuncle, lung carbuncle, gynecological epigastric pain, postpartum blood stasis, and eczema in ancient times ( Chen and Han, 2017 ). Modern pharmacological studies have found that it has effects of anti-cancer, anti-inflammation, anti-pathogenic microorganisms, anti-oxidation, sedation, and hypnosis ( Wang et al., 2019a ). Nowadays, Herba Patriniae is widely used in the respiratory system, digestive system, genitourinary system, gynecology, dermatology and other multi-disciplinary diseases in clinical practice ( Zhu and Jiang, 2015 ), and the number of applied patents increases every year ( http://pss-system.cnipa.gov.cn ). In view of its high content of amino acids, vitamins, minerals and other nutrients, Herba Patriniae is not only regarded as a potherb with healthy value, but also processed into tea products ( Su et al., 1999 ; Zeng et al., 2019 ; Zhong et al., 2001 ). Fig. 1 Two species of Herba Patriniae. (A) Patrinia villosa Juss.; (B) Patrinia scabiosaefolia Fisch (A: http://www.cvh.ac.cn/spm/CSH/CSH0005548 ; B: http://www.cvh.ac.cn/spm/SYAUF/SYAUF010108 ). Fig. 1 Two species of Herba Patriniae. (A) Patrinia villosa Juss.; (B) Patrinia scabiosaefolia Fisch (A: http://www.cvh.ac.cn/spm/CSH/CSH0005548 ; B: http://www.cvh.ac.cn/spm/SYAUF/SYAUF010108 ). In the past decades, an increasing number of scholars have studied the chemical constituents and pharmacological effects of Herba Patriniae. Interestingly, based on these studies, we found that there are many different/same characteristics between PS and PV . Both of them are official species for Herba Patriniae, but differentiated clinical uses of them in different diseases may be better for the clinical outcome. Unfortunately, we cannot found a comprehensive and updated review on the same/different characteristics of the two sources of Herba Patriniae, and actually, these two species also have not been differentiated in clinical uses. Therefore, this review aims to systematically summarize the similarities and differences from the aspects of the traditional uses, botanical description, phytochemistry, pharmacology, and quality control of these two species of Herba Patriniae, as well as being evidences for their clinical application and further research.

“Heat” is a conception in traditional Chinese medicine, which is the synonym of “fire” and is the predominant pathogenic factor of summer. Excessive “heat” consumes Yin fluid and results in imbalance between Yin and Yang, which can produce endogenous toxins lurking in the human body ( Tu et al., 2016 ). With activities of heat-clearing and detoxifying, Herba Patriniae exerted anti-cancer, anti-inflammatory, antioxidant, antimicrobial effects, as well as a sedative, hypnotic, proangiogenic, anti-diabetic, antipruritic, and anti-diarrheal effects in vitro and in vivo . There are different pharmacological effects between PV and PS . We have enlisted an overview of the modern pharmacological studies in the following sections ( Table 4 ).

( PV ); Patrinia scabiosafolia Fisch. ( PS ). Not indicate species. Cancer is one of the main diseases that endanger human health, and recent studies have shown that Herba Patriniae plays an important role in anti-cancer. Some extracts of Herba Patriniae have been used to study the anti-cancer effect in several human cancer cell lines. Among them, the ethanol extract of PS and PV showed remarkable anti-cancer effects both in vitro and in vivo . Many studies showed the anti-cancer effect of the ethanol extract of PS. Chen et al. (2013) discovered that the ethanol extract of PS suppressed the proliferation, migration, and tube formation of HUVECs (human umbilical vein endothelial cells) at the dose of 0.25–2 mg/mL. According to the studies of Liu et al. (2013b) and Zhang et al. (2015) , it also inhibited the angiogenesis and the expression of CyclinD1 and CDK4 in HT-29 (human colon cancer cells), increased the ratio of pro-apoptotic Bax to anti-apoptotic Bcl-2, induced the activation of caspase-3 and -9 in HT-29 cells via the mitochondrial-dependent pathway, and decreased the proliferation of HT-29 cells by G1/S cell cycle arrest. When the ethanol extract of PS was intragastrically administrated to colorectal cancer mice at the dose of 1.93 g/kg, the tumor volume was significantly decreased, and the intratumoral microvessel density and the expression of PCNA were reduced in tumor tissues. Huang et al. (2019a) found that the ethanol extract of PS decreased the drug resistance of HCT-8/5-FU (human colorectal cancer cells) by inhibiting AKT pathway and inducing apoptosis. Moreover, in human multiple myeloma U266 cells, it dramatically suppressed proliferation, decreased Cyclin D1 and Bcl-2 mRNA levels, and eventually induced apoptosis in a dose-dependent manner (0.25–1 mg/mL), with a mechanism of suppressing STAT3 activation ( Peng et al., 2011 ). When the concentration of the ethanol extract of PS was 1.0 mg/mL, the necrotic and apoptosis rate of 786-O cells (human renal cell carcinoma) were markedly increased, and the intracellular ROS and Ca 2+ levels were significantly elevated. In addition, it significantly inhibited SIRT-1 and mTOR signaling. Therefore, Li et al. (2018) believed that the ethanol extract of PS induces the death of 786-O cells through metabolic disorders mediated by SIRT-1 and mTOR signaling. On the other hand, the studies on anti-cancer effect of ethanol extract of PV were relatively less. For example, Chen et al. (2019c) found that the ethanol extract of PV increased the tumor inhibition rate of U14-bearing mice with the inhibitory rate 49.19% and 54.23% at the dosage of 10 g/kg and 15 g/kg, respectively. However, the dose level of 10 g/kg and 15 g/kg is very high, and the extraction process of the extract needs to be further optimized. The other extracts of Herba Patriniae also showed potential anti-cancer effects, though these effects may have some differences between them. The essential oil extract of PS showed a significant dose-dependent inhibition effect on 8 kinds of tumor cells at dose of 50–200 μg/mL ( Lin et al., 2018 ). Ethyl acetate extract from PS and Patrinia monoterpene iridoid ether esters extract from PS or PV were evaluated on HepG2 (human liver hepatocellular carcinoma) or MCF7 (human breast adenocarcinoma cells) for the inhibition of proliferation and induction of apoptosis. Results showed that the expression levels of Bcl-2/Bcl-xL, Cdc2, and Cyclin B1 proteins were down-regulated, while the expression levels of Bax and caspase-3 proteins were up-regulated. These results suggested that the anti-hepatoma and anti-breast cancer effects of Herba Patriniae can also be achieved by caspase-independent mitochondrial cell death pathway ( Chiu et al., 2006 ; Ji et al., 2019 ). There are many kinds of compounds within Herba Patriniae, which may support the anti-cancer effect of Herba Patriniae, and hence, scholars wish to clarify what kinds of compounds exert this pharmacological effect. After treatment with the saponins extract of PV , the EMT and NF-κB signaling pathways were down-regulated in vitro , which subsequently inhibited the invasion and metastasis of human colorectal cancer cells ( Xia et al., 2018 ). Moreover, at the dose of 50 mg/kg and 100 mg/kg, it also effectively reduced the weight of U14 cervical tumor in vivo (35.1% and 57.1%, respectively), which was closely related to the increase of apoptosis and G0/G1 tumor cells and the decrease of mutant P53 and Bcl-2 protein expression ( Zhang et al., 2008 ). Patrinia-glycoside B-II from PS showed strong cytotoxic activities against HeLa (human cervical carcinoma cells), HepG2, HT1080 (human fibrosarcoma cells), A549 (human lung adenocarcinoma cells), A375-S2 (human melanoma cells), K562 (human erythroleukemic cells), HL60 (human leukemia cells), and U937 (Human leukemic monocyte lymphoma cells) with an IC 50 of 5.4, 4.2, 18.0, 27.9, 15.8, 6.2, 6.6, and 5.5 μM, respectively ( Ren et al., 2013 ). Therefore, terpenoids in Herba Patriniae can be used as an anti-cancer potential component for in-depth research in vivo and in vitro . Flavonoids, as another kind of active compounds rich in Herba Patriniae, have also been proved to have considerable anti-cancer effects. Peng et al. (2006c) carried out the growth inhibition experiments on A498 (human kidney cancer cells), A549, BEL-7402 (human hepatocellular carcinoma cells), HT-29, MCF-7, SGC-7901 (human gastric adenocarcinoma cells), and K562 with 6 flavonoids isolated from PV . The results showed that (2S)-5, 7, 22S 62S)-5, 7, showed 8-di (γ, γ-dimethylallyl) flavanone, (2S)-5, 7, 28- 68- tetrahydroxy-6-lavandulylated flavanone and (2S)-5, 7, 2te 6tetrahydroxy-6-lavandulylated fl flavanone exhibited high anticancer activities (IC 50  < 7 μg/mL) in a dose-dependent manner, and when the concentration of these compounds exceeded 15 μg/mL, the proliferation of cancer cells was completely inhibited, especially for K562 cells (IC 50  < 3.1 μg/mL). Patriniaflavanone A isolated from PV and the total flavonoid extracts of PS and PV showed obvious dose-dependent inhibitory effects on SMMC7721 hepatocarcinoma cells (0.125–10 mg/mL). Meanwhile, the total flavonoids extract of PV has a better inhibitory effect on the growth of SMMC-7721 cells than PS ( Wei et al., 2013b ; Xiang et al., 2016 ; Zhao et al., 2019 ). Besides, impecylone A isolated from PV showed an inhibition effect on 2 kinds of tumor cells at the doses of 12.5–50 μM ( Liu et al., 2019b ). Herba Patriniae has been widely used in traditional medicine to treat pelvic inflammatory disease (PID), pancreatitis, colitis, and other inflammatory diseases ( Ji, 2006 ; Qiu, 2005 ; Zhang, 1997a ). Modern pharmacological studies have demonstrated that various effective extracts of Herba Patriniae showed anti-inflammatory effects in different inflammatory-related diseases. In vitro , the ethyl acetate extract (10–100 μg/mL) and essential oil extract (100–200 μg/mL) of PS inhibited the secretion of pro-inflammatory cytokines in RAW 264.7 (murine macrophage cells) or BV-2 (mouse microglia cells) in a dose-dependent manner, respectively ( Lee et al., 2012 ; Lin et al., 2018 ). In vivo , both the ethanol extract of PS (600 mg/kg) and the 70% ethanol extract of PV (0.55 g/kg) showed strong anti-inflammatory effects in rats with PID, which inhibited the infiltration of inflammatory cells and the production of cytokines in the upper genital tract of PID rats, as well as the levels of pro-inflammatory cytokines in serum ( Zheng et al., 2012 ; Zou et al., 2015 ). On the other hand, the water extract and methanol extract of PS and the total flavonoids of Herba Patriniae exhibited obvious anti-inflammatory effects in animal models of acute pancreatitis, ulcerative colitis, and focal cerebral ischemia-reperfusion, respectively. All of these extracts inhibited the secretion of pro-inflammatory cytokines, such as IL-1β, IL-6, and TNF-α ( Cho et al., 2011 ; Seo et al., 2006 ; Wei et al., 2019 ). Although these nonclinical pharmacological studies on Herba Patriniae extracts have indicated the good pharmacological effects of Herba Patriniae in the anti-inflammatory field, further clinical studies are more needed to extend its clinical use. Recently, the antioxidant effect of Herba Patriniae has been evaluated in vivo and in vitro , providing information on the pharmacological activity of both mixtures and single compounds. The phenylethyl flavones isolated from PV (25 μM) showed a significant antioxidant effect, and this effect was achieved through the modulation of the mir-144-3p/Nrf2 pathway, thereby eliminating intracellular ROS in vitro ( Feng et al., 2018 ). The water, ethanol, and volatiles extract from PV and PS possessed strong antioxidant effect by DPPH assays, and especially the chlorogenic acid and total flavonoids in the water extracts of PS exhibited stronger free radical scavenging ability ( Lin et al., 2018 ; Sun et al., 2018 ; Xie et al., 2008 ). Chlorogenic acid and flavonoids of Herba Patriniae are be regarded as bioactive constituents for antioxidant activity. In vivo , it's worth noting that the 60% ethanol extract of PV had a remarkable antioxidant effect on mice with acute liver injury, which is reflected by the reductions of ALT and AST activities in the serum, MDA content and LDH activity in the liver, and the enhanced liver T-SOD, T-AOC and GSH activities ( Huang et al., 2019b ). These results provide ideas for further research on its traditional medicine. Herba Patriniae is widely used in traditional medicine to treat respiratory diseases caused by viruses. At present, the researches on the antiviral effect of Herba Patriniae were mainly focused on the respiratory syncytial virus (RSV) and severe acute respiratory syndrome (SARS) virus. Li et al. (2006) investigated the antiviral effects of water extract of PS or PV against the SARS virus in vitro . The extract possessed a strong inhibition rate of 45.0% at a concentration of 750.0 mg/mL, and could effectively quench the free radicals that occurred in the process of UV irradiation on λ-lysogenic cells. Li et al. (2004) reported that polysaccharide mixture of PS or PV has an effective inhibitory effect on RSV in HeLa cells, with a therapeutic index of 116.12 and an EC 50  = 0.0986 mg/mL. These results provide a potential for using animal models to further explore the anti-virus infection mechanism of Herba Patriniae. In vitro , the antibacterial effect of water extract and ethanol extract from PS were tested on Staphylococcus aureus , Streptococcus , Pasteurella , Salmonella , and Escherichia coli . Among them, the water extract showed a strong inhibitory effect against Staphylococcus aureus, Streptococcus , and Escherichia coli at a concentration of 0.5 g/mL ( Tan et al., 2003 ). However, this paper have not showed the reason for the different antibacterial effects between water extract and ethanol extract, and further study should be carried out to illustrate this issue. In the past researches, saponins, volatile oils, organic acids and flavonoids were considered as the main chemical components within PS . These compounds may have played a key role in the antibacterial process. Among them, the content of total flavonoids and organic acids in the water extract of PS is higher than that of ethanol extract ( Sun et al., 2018 ), and this may be the reason for the results of Tan et al. (2003) . The 70% ethanol extract of PV showed dose dependent growth inhibition in Staphylococcus aureus , Escherichia coli , Proteus spp and Bacillus subtilis at 12.5–100 mg/mL, and has high UV radiation stability and thermostability ( Dai and Lin, 2011 ). The tannin extract of PV not only had a significant inhibitory effect on Escherichia coli , Bacillus subtilis and Staphylococcus aureus , but also on Shigella dysenteriae and Salmonella typhimurium , with an inhibition rate of 23.45 %–50.78% ( Fan, 2014 ). Besides, Fu et al. (2017) discovered that the water extract of Herba Patriniae showed an obvious inhibitory effect on key genes related to biofilm, and could decrease biofilm formation and change the structure of the biofilms of Pseudomonas aeruginosa . Nevertheless, this study is lack of dose-dependent results, and a test on the drug exposure time to kill bacteria may also be meaningful for the antibacterial study. Besides, its further study is necessary to associate the antibacterial activity with the corresponding diseases. Taken together, as a natural antimicrobial plant, Herba Patriniae is worthwhile to further study the active components, and besides, it also could be put into the industrial production of food and feed. Diseases caused by fungal infection include superficial, subcutaneous and deep mycoses, which have a high incidence and easily cause systemic infectious diseases ( Liu and He, 2014 ; Ran et al., 2017 ). Wu (2017a) studied the anti-fungal effect of Herba Patriniae on Cryptococcus neoformans , Candida albicans , Trichophyton rubrum and Aspergillus fumigatus , but it showed no inhibitory effect on these four fungi. Fan (2014) investigated the inhibitory effect of tannin extract of PV on Aspergillus niger , Aspergillus flavus , and Saccharomyces cerevisiae , and found that its inhibitory effect on these three fungi was poor, and the inhibition rate was less than 28.03%. At present, there are few studies on the anti-fungal effect of Herba Patriniae, and the anti-fungal effect of Herba Patriniae is worthy of further study. At present, neurological diseases have become a major problem affecting people's quality of life. In traditional medicine, Herba Patriniae has a good curative effect on insomnia and neurasthenia ( Qiu, 2005 ; Yang, 2002 ). A study conducted by Luo et al. (1986) demonstrated that 60% ethanol, and volatile oil extract from PS have sedative and hypnotic effects. In addition, the ethanol extract of PS at a dose of 1 g/mL showed an observable sedative effect on mice. Its sedative effect was stronger than that of the water extract and its intensity was similar to that of pentobarbital. The 95% ethanol extract of PS was further extracted with petroleum ether, chloroform, ethyl acetate, and n-butanol respectively for sedation and hypnosis experiment. The sedative effect of the n-butanol extract was the most significant among the four different polarity extracts ( Tan et al., 2003 ; Xu et al., 2007 ). Therefore, the n-butanol extraction part of PS is considered to be an effective sedative extract. Moreover, the water extract of PV also has obvious sedative and central nervous system inhibitory effect, which can shorten the falling asleep time and prolong the sleep time induced by pentobarbital sodium, and the effect was enhanced with the increase of dose (20–60 mg/kg) ( Chen et al., 2005 ; Zhong et al., 2004 ). Although these studies support the traditional medication experience of Herba Patriniae, systematic studies are needed to determine the bioactive compounds of this effect. The proangiogenic effect of PV has been tested on HUVECs, in an ex vivo mouse aortic ring assay, and in an in vivo murine hindlimb ischemia model. In vitro and in vivo pharmacological studies have indicated that the water extract of PV significantly promoted cell proliferation and migration, and induced angiogenesis via activating the FAK signaling pathway ( Jeon et al., 2010 ). In traditional medicine, Herba Patriniae is widely used in the treatment of various skin diseases, such as psoriasis vulgaris, itching ( Wang and Wang, 2002 ; Yan et al., 2015 ; Zhu and Jiang, 2015 ). Tohda et al. (2000) reported that the methanol extracts of PV exhibited a significant inhibitory on substance P-induced itch-scratch response. Although the mechanism of antipruritic action is not clear, these results demonstrated that PV could be developed as an antipruritic for the treatment of cutaneous diseases. In addition, decoction containing Herba Patriniae is reported to be used for diarrhea ( Qiu, 2005 ). A study conducted by Zhang et al. (2019a) demonstrated that the 60% ethanol, dichloromethane layer, ethyl acetate layer, N-butanol layer, and water layer extracts of PV exhibited anti-diarrheal effects in a dose-dependent manner (100–400 mg/kg), and the dichloromethane layer showed the strongest anti-diarrheal effect in vivo and in vitro . Furthermore, Patrinoside and patrinoside A isolated from PS were shown to exert a significant effect on improving insulin resistance in 3T3-L1 adipocytes via activation PI3K/Akt signaling pathway, which plays an important role in type 2 diabetes ( Liu et al., 2019c ). Although both PV and PS contain iridoids, there is no report on the insulin resistance of PV . Moreover, there is no research on the proangiogenic, antipruritic, and anti-diarrheal effects of PS . Therefore, there are some differences in pharmacological effects between these two species of Herba Patriniae. It is suggested that further study should be conducted to determine the difference of pharmacological activities between the two plants, so as to provide scientific reference for safe and effective medication.

Triterpenoid aglycones and triterpenoid saponins are one of the main active constituents in Herba Patriniae. To date, more than 66 compounds (1–66) have been isolated from Herba Patriniae. It's worth noting that 62 compounds are in PS , 7 compounds are in PV , and only 3 compounds are in both PS and PV . According to the aglycone, all of them were divided into oleanane type (1–57) and ursane type (58–66). Further, the oleanane type is divided into 5 different types, including oleanolic acid type (1–29), 13, 28-epoxy-oleanolic acid type (30–34), 11, 12 epoxy-13, 28-cyclooxy-oleanolic type (35–36), 3-carbonyl oleanolic acid type (37–40), and hederagenin type (41–57) according to their structures. Their chemical structures were draw by ChemBioDraw Ultra 14.0 and described in Fig. 2 . Fig. 2 Chemical structures of triterpenoid aglycones and triterpenoid saponins in Herba Patriniae. Fig. 2 Chemical structures of triterpenoid aglycones and triterpenoid saponins in Herba Patriniae. Oleanolic acid (8), hederagenin (44) and ursolic acid (62) are typical representatives of triterpenoid aglycones in Herba Patriniae. An increasing number of studies have proved that oleanolic acid (8) possess antitumor ( Mbaveng et al., 2020 ), antimicrobial ( Zhou et al., 2020 ), and antiviral ( Meng et al., 2019 ) activities. Hederagenin (44) gave anti-inflammatory and anti-apoptotic activities to alleviate ethanol-induced liver damage ( Kim et al., 2017 ). Ursolic acid (62) has been reported with antioxidant and antiproliferative activities ( Zhang et al., 2020 ), as well as protective effects against cisplatin-induced ototoxicity ( Di et al., 2020 ) and alleviates hypercholesterolemia ( Hao et al., 2020 ). In addition, giganteaside D (2) was found with the induction effect on ROS-mediated apoptosis ( Liu et al., 2016b ). Alpha-hederin (50) showed acute anti-inflammatory activities in carrageenan-induced rat paw edema ( Gepdiremen et al., 2005 ). But the biological activities of most triterpenoid aglycones and triterpenoid saponin were still unclear. Flavonoids is a class of famous natural products with widely biological activities, such as anti-oxidation, anti-inflammation and anti-tumor. There are 43 flavonoids were identified in Herba Patriniae. They are mainly classified into five groups according to the structure of aglycone, including flavones (67–84), flavonols (85–98), flavonones (99–102), isoflavanones (103–104), and other types (105–109). Luteolin (75), apigenin (78) and scutellarin (80) were blong to flavones. All of them have been widely studied in cardiovascular and tumor fields ( Park et al., 2020 ; Xu et al., 2020 ; Bao et al., 2020 ). Isoorientin (82) and isovitexin (83) were two specific compounds in Herba Patriniae due to C-6 forming a C–C bond. Quercetin (86) and kaempferol (88) are two of the most common flavonols in dicotyledons. Compounds 85, 87 and 93 were derived from quercetin, while compounds 89, 90, 91, 92, 94, 95, 96, 97 and 98 were derived from kaempferol. It is interesting to note that more than 43 flavonoids (67–109) have been identified from PV , but are rarely found in PS (75, 85, 86, 88). Their chemical structures are prescribed in Fig. 3 . Fig. 3 Chemical structures of flavonoids in Herba Patriniae. Fig. 3 Chemical structures of flavonoids in Herba Patriniae. To date, only 13 organic acids (110–122) have been identified from Herba Patriniae. The contents of chlorogenic acid (110), caffeic acid (111) and protocatechuic acid (115) are higer. These phenolic compounds possess many health-promoting properties, including antioxidant, antiinflammatory, antidiabetic, and antihypertensive activities ( Al-Megrin et al., 2020 ; Paciello et al., 2020 ; El-Sonbaty et al., 2019 ; Li et al., 2020 ). For example, protocatechuic acid administration for twelve-week could improves insulin-induced vasorelaxation in aging spontaneously hypertensive rats. Of these, 10 organic acids (110–114 and 117–121) are in PV , 9 organic acids (110–116, 119 and 122) are in PS . Among them, 6 compounds are in both PS and PV . Their chemical structures are shown in Fig. 4 . Fig. 4 Chemical structures of organic acids in Herba Patriniae. Fig. 4 Chemical structures of organic acids in Herba Patriniae. Iridoids are a kind of very important natural products in plant kingdom, structurally characterized with bicyclic cis-fused cyclopentane-pyrans or cleavage of a bond in the cyclopentane ring (secoiridoid). Clinically, iridoids extract or traditional Chinese medicine rich in iridoids have been proved with anti-inflammatory, antiviral and antitumor effects, as well as protection of cardiovascular and immunomodulatory activities ( Wang et al., 2020 ; Jie et al., 2015 ; Ji et al., 2019 ; Luan et al., 2019 ). To date, 21 iridoids (123–143) have been isolated in Herba Patriniae. Of these, loganin (131), loganic acid (132) and morroniside (136) are the compounds with more reported biological activities. Loganin has been proved with inhabitation effect on inflammatory response ( Wen et al., 2020 ; Wei et al., 2013a ) and mitigative effect on osteoarthritis ( Hu et al., 2020 ). Morroniside has shown protective effect against H 2 O 2 -induced damage in human neuroblastoma cells ( Zhong et al., 2017 ). It is worth pointing out that 8 iridoids were obtained from PV , and 14 iridoids were isolated from PS . Only 1 compound (131) was a common constituent of the two plants. Their chemical structures were prescribed in Fig. 5 . Fig. 5 Chemical structures of iridoids in Herba Patriniae. Fig. 5 Chemical structures of iridoids in Herba Patriniae. The volatile constituent is one of the most abundant compounds in Herba Patriniae with many biological activities, such as antioxidant, antiinflammatory and anti-tumor effects, and it also proved with sedative and hypnotic effects ( Lin et al., 2018 ; Luo et al., 1986 ). Approximately 69 volatile compounds (144–212) have been isolated from Herba Patriniae. All the volatiles were obtained by GC-MS method and list here for reference. Of these, 57 volatiles were isolated from PS , and 17 volatiles were separated from PV . Their chemical structures were prescribed in Fig. 6 . These two sources of plants have 5 common volatile constituents. Fig. 6 Chemical structures of volatile in Herba Patriniae. Fig. 6 Chemical structures of volatile in Herba Patriniae. In addition to the above compounds, Herba Patriniae also contains steroids (213–216), lignans (217–220), sesquiterpene lactone glycosides (221), amides (222–223), and other compounds (224–233). Of these, 17 compounds were isolated from PV , and 7 compounds were obtained from PS . Compounds 213 and 215 are common components of the two plants. Their chemical structures were prescribed in Fig. 7 . Fig. 7 Chemical structures of other compounds in Herba Patriniae. Fig. 7 Chemical structures of other compounds in Herba Patriniae.

Pharmacokinetics is conducive to understanding the process of drug absorption, distribution, metabolism and excretion in the body. Unfortunately, there are few investigations on the pharmacokinetics of Herba Patriniae. Han et al. (2020) determind the serum pharmacochemistry after intragastric administration of total flavonoids extract from PV in rats by UPLC-Q-TOF-MS method. As result, 7 prototypical components (chlorogenic acid, caffeic acid, scutellarin, isoorientin, isovitexin, luteolin, and apigenin) and 7 metabolic components (Hydrocaffeate, scutellarein, Sulfated apigenin, sulfated luteolin, sulfated kaempferol, methylated kaempferol and one unknown compound) were detected in plasma, which might be the pharmacodynamic basis of its antitumor effect ( Han et al., 2020 ).
