Results indicated that S. pallida maintained high nodulation and nitrogen efficiency even at late growth stages while accumulating significant levels of Fe, Pb, Zn, and Cu in its aerial parts. Phenol content varied significantly (p<0.05) by phenological stage and plant part, with a high concentration of total extractable polyphenols (7.73 %DM) and tannins (6.97 %DM) recorded during the vegetative stage. Antioxidant activity, as shown by DPPH radical scavenging (IC 50 of 0.126 mg/mL), was comparable to the control (BHT, IC 50 of 0.110 mg/mL). Anti-lipid peroxidation and ferric reduction potential were highest during flowering, with values outperforming controls in some assays. HPLC-ESI-MS/MS analysis identified 38 compounds, with high levels of 4-Hydroxy benzoic acid, rutin, vanillic, gallic, and p-coumaric acids. These findings highlighted S. pallid as a promising forage species for remediating heavy metal-contaminated pastures and promoting sustainable land use. S.pallida heavy metals polyphenolic antioxidant activity HPLC-ESI-MS/MS and phytoremediation Introduction Environmental pollution by heavy metals from is becoming a real issue with a large effect on agricultural productivity, particularly when they depend on symbiotic relationships. Variousanthropogenic activities have persistently contributed to soil contamination, particularly with heavy metals, which often remain in the environment and have detrimental effects on living organisms (Leila et al. 2020 ; Barillaro et al. 2024 ). Such a situation requires the development of methods, such as soil flushing, vapor extraction, landfilling, leaching, and soil fixation, have been extensively implemented to address metal contamination in soil (Marques et al. 2009 ). However, these methods are expensive, labor-intensive, and often environmentally disruptive, highlighting the need for more sustainable and cost-effective alternatives. In this context, bioremediation involves plants with a high capacity to bio-concentrate and/or bio-immobilize toxic metals from soil, appears as a good and eco-friendly strategy to minimize the impact of heavy metals in soil. In Mediterranean pastures, species of the genus Sulla (a Fabaceae) represent a good asset in agricultural economics because of their quality as forage crops (Kadi et al. 2011 ; Issolah et al. 2014 ; Errassi et al. 2018 ) and ability to improve soil fertility (Molinu et al. 2023 ). Those species, composed of various annual and perennial species, display a high level of genotypic diversity (Duan et al. 2015 ; Liu et al. 2017 ), as well as the capacity to form specialized symbiotic relationships with soil bacteria (Kishinevsky et al. 2003 ; Benhizia et al. 2004 ). Among Sulla species, Sulla pallida Desf. synonym Hedysarum pallidum Desf. (Choi and Ohashi 2003 ), is a north-African endemic species, preferentially allogamous (Neila and Mohamed 2001 ), recognized for its nutritional richness and ability to in arid zones such as those located in northeastern Morocco (El Yemlahi et al. 2024 ). The plant steel grows spontaneously in quite diverse environments (Abdelguerfi-Berrekia et al. 1991; Moore et al. 2006 ), including those of mining area located in Algeria (Benhizia et al. 2004 ; Benhamdi et al. 2014 ; Kassa-Laouar et al. 2019 ) and in Morocco (Smouni et al. 2010 ; Lamin et al. 2021 ), and suggesting eco - physiological adaptation to this particular environment. Therefore, this original research aims to evaluate the phenolic content and antioxidant activity of natural populations of S. pallida , a forage legume growing spontaneously on mining sites in Northeast of Morocco.The findings could provide a basis for improving soil health and promoting sustainable land use in polluted environments. Material and methods Plant sampling and nodulation assessment Plant samples (stems and roots) of S.pallida , were collected from an abandoned mining site in the North-eastern of Morocco. Samples were hand-clipped at the two growth stages, early vegetative and flowering stages. Nodulation ability was evaluated using a nodule-scoring chart proposed by Howieson and Dilworth (2016). Effectiveness in nitrogen fixation was assessed at the flowering stage, by measuring shoot dry weight and total N using the Kjeldahl method (Bremner 1965). Heavy metal analysis Plants were oven-dried at 60°C, then grounded using POLYMIX® PX-MFC 90 D Hammer mill. Furthermore, a mixture of soil samples was taken from the surface layer (0-15 cm), air-dried, and ground using a porcelain mortar and pestle. The samples were homogenized and sieved for heavy metal analysis, using an Axios X-ray fluorescence (XRF) spectrometer at the Units of Technical Support to Scientific Research (UATRS) of the National Centre for Scientific and Technical Research (CNRST) in Rabat, Morocco. The transfer factor (TF) of heavy metal from soil to plants was determined using the following formula: Where “MP” is themetal concentration in the plant, and “MS” is themetal concentration in the soil. Phenolics compounds analysis Plant samples were dried at 50°C and were tested for total extractable phenolics (TEP) and tannins (TET) employing the Folin Ciocalteu method following the procedures outlined by (Makkar 2003).Total extractable condensed tannins (ECT) were determined using the butanol-HCl-Fe 3+ method (Porter et al. 1985). The liquid extracts were further dried at 40°C and the solid residue was then solubilized in distilled water to determine total flavonoid content (TFC) using the aluminum chloride colorimetric method as outlined by (Nurcholis et al. 2021). Antioxidant activity evaluation Free radical scavenging activity The radical-scavenging activity was investigated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) bioassay following the procedure approved by (Mensor et al. 2001). A concentrated solution of extracts used to determinetotal flavonoid contentwas prepared and then diluted to 2 mg/mL, 1 mg/mL, and 0.5 mg/mL. Briefly, 2.5ml of the serial dilution was transferred into glass test tubes and mixed with 1 mL of 0.3 mM DPPH solution newly prepared in methanol. The mixture was then incubated at room temperature in the dark for 30 minutes. Methanol and BHT (butyl hydroxytoluene) were utilized as negative and positive controls respectively. The absorbance was measured at 517 nm and the antioxidant activity was then calculated as percent inhibition as follows: Where “Acontrol” is the absorbance of the control experiment and “Asample” is the absorbance of the sample. Ferric reducing antioxidant power The antioxidant activity of S. pallida extracts was additionally analyzed using the ferric reducing antioxidant power (FRAP assay) as earlier stated by (Lfitat et al. 2021). Briefly, 2.5 ml of extract solutions prepared at different concentrations werecombined with equal volumes of phosphate buffer (0.2 M, pH 6.6) and 1% K 3 Fe[CN] 6 . The obtained solution was incubated in a water bath at 50°C for 20 min,thencentrifuged at 3000 rpm for 10 min after adding 2.5 ml of 10% TCA (Trichloroacetic Acid). 2.5 mL was taken from the supernatant and mixed with 2.5 mL of distilled water and 100 µL of 0.1% iron chloride (FeCl 3 ). The absorbance of the reaction mixture was measured at 700 nm. An increase in the absorbance indicates the high ferric-reducing ability of the extract. Distilled water was used as a blank and rutin as a positive control. Antioxidant assessment utilizing a β-carotene-linoleate method The anti-lipid peroxidation activities of the samples were assessed by the b-carotene/linoleate model system (Miller 1971). A stock solution of β-carotene and linoleic acid was prepared with 2 mL of β-carotene (2 mg in 10 mL of chloroform) added to a tube containing 40 mg of linoleic acid and 400 mg of Tween 40. After combining the two phases, the chloroform was completely evaporated, and then 50 mL of oxygen-saturated distilled water was added to the mixture with stirring.Five milliliters of the prepared emulsion were placed into a set of tubes, each containing 0.2 mL of various concentrations of the extracts or BHT. Immediately after the emulsion was added, the absorbance was measured at 470 nm using a UV spectrophotometer. Finally, the tubes were incubated in a water bath at 50°C, and the absorbance was taken after 120 minutes. The antioxidant activity was then calculated as inhibition % of the β-carotene, using the following formula: Where: “Aantiox 0 ” and “Aantiox 120 ” are the absorbance of the sample at 0 and 120 min respectively, and “Acontrol 120 ” is the absorbance of the control at 120 min. Half minimal inhibitory concentration (IC 50 ) The extract concentration corresponding to 50% inhibition of DPPH radicals scavenging was extrapolated from the curves of the percentage inhibition against the concentration used.The results are reported as half minimal inhibitory concentration (IC 50 ), which indicates the quantity of extract or standard required to reduce the initial concentration of DPPH radicals by 50%. Similarly, the sample concentration providing 50% β-carotene bleaching (IC 50 ) was determined by plotting the inhibition percentages against the sample concentrations. Finally, the extract concentration needed to reach 0.5 of absorbance for ferric reducing power was calculated from the graph of absorbance, and the results are presented as half minimal inhibitory concentration (IC 50 ). The lower (IC 50 ) value is related to a higher antioxidant activity. HPLC-Electrospray Ionization-Mass Spectrometry ( HPLC-ESI-MS/MS) analysis Reagents and standards Cyanidin-3-glucoside chloride, delphinidin-3,5-diglucoside chloride, delphinidin-3-galactoside chloride, petunidin-3-glucoside chloride, malvidin-3-galactoside chloride, quercetin-3-glucoside and kaempferol-3-glucoside were purchased from PhytoLab (Vestenbergsgreuth, Germany). The remaining 31 analytical standards of the 38 phenolic compounds were supplied by Sigma-Aldrich (Milan, Italy). Individual stock solutions of each analyte, at a concentration of 1000 mg L −1 , were prepared by dissolving pure standards in HPLC-grade methanol and storing them in glass stoppered bottles at 4 ° C, except for anthocyanins, which were stored at − 15 ° C until analysis. Standard working solutions at various concentrations were prepared daily by appropriate dilution of the stock solutions with HPLC-grade methanol. Formic acid (99%) was obtained from Merck (Darmstadt, Germany). Analytical-grade hydrochloric acid (37%) was obtained from Carlo Erba Reagents (Milan, Italy). HPLC-grade methanol was supplied by Sigma-Aldrich (Milano, Italy). Deionized water (> 18 MΩ cm resistivity) was further purified using a Milli-Q SP Reagent Water System (Millipore, Bedford, MA, USA). All solvents and solutions were filtered through a 0.2 μm polyamide filter from Sartorius Stedim (Goettingen, Germany). Before HPLC analysis, all samples were filtered with Phenex™ RC 4 mm 0.2 μm syringeless filter, Phenomenex (Castel Maggiore, BO, Italy). HPLC-ESI-MS/MS HPLC-ESI-MS/MS analysis was conducted on the aerial parts of S. pallida using an Agilent 1290 Infinity series and a Triple Quadrupole 6420 from Agilent Technology (Santa Clara, CA) equipped with an electrospray ionization (ESI) source operating in negative and positive ionization modes. The instrument was allowed to perform a single run with polarity switching without any problems. MS/MS parameters of each analyte were optimized in flow injection analysis (FIA) (1 μL of a 10 mg L −1 individual standard solution) by using Optimizer Software (Agilent). The separation of target compounds was achieved on a Synergi Polar–RP C18 analytical column (250 mm x 4.6 mm, 4 µm) from Phenomenex (Chesire, UK). The column was preceded by a Polar RP security guard cartridge (4 mm x 3 mm ID). The mobile phase was a mixture of (A) water and (B) methanol, both with formic acid 0.1%, at a flow rate of 0.8 mL min −1 in gradient elution mode. The composition of the mobile phase varied as follows: 0–1 min, isocratic condition, 20% B; 1–25 min, 20–85% B; 25–26 min, isocratic condition, 85% B; 26–32 min, 85–20% B. All solvents and solutions were filtered through a 0.2 μm polyamide filter from Sartorius Stedim (Goettingen, Germany). The injection volume was 2 μL. The temperature of the column was 30 ° C, and the temperature of the drying gas in the ionization source was 350 ° C. The gas flow was 12 L/min, the nebulizer pressure was 55 psi, and the capillary voltage was 4000 V. Detection was performed in the dynamic-multiple reaction monitoring (dynamic-MRM) mode, and the dynamic-MRM peak areas were integrated for quantification. The most abundant product ion was used for quantitation, and the others for qualification. The specific time window for each compound (Δ retention time) was set at 2 min. The selected ion transitions and the mass spectrometer parameters for the analyzed compounds are reported in Table 7. Statistical analysis All experiences were conducted in three triplicatesand expressed as means ± standard deviation (SD). Analysis of variance (ANOVA) was carried outusing (Proc GLM) procedure of SAS (SAS Institute Inc., Cary, NC, USA), following the model equation: Where “µ” is the overall mean, “s” is the growth of the stage, and “e“ is a random error. Results Symbiosis and nodulation evaluation Primary results showed the occurrence of S. pallida on alkaline (8.62) silty soil, rich in potassium (289 ppm) and poor in phosphorus (9.50 ppm) and nitrogen (0.15%).Furthermore, the on-field survey of examined plants showed that S. pallida had a great symbiosis ability and forms extremely abundant, large, and pink root nodules (Howieson and Dilworth 2016). Results (Table 1) showed high productivity (up to 41.74% of dry matter at the flowering stage) and high nitrogen content (4.14% at the vegetative stage) of S. pallida at a mining site located in Northeast Morocco. Heavy metal analysis From the elemental analysis point of view, the results of five soil heavy metal analyses are depicted in Table 2. Results showed low concentrations of manganese (1100 mg/kg) and iron (39450 mg/kg) in comparison with maximum permissible limits set by official organizations such as World Health and Food and Agricultural Organization (Table 2). By contrast, high concentrations of lead (8755 mg/kg), followed by zinc (3710 mg/kg) and copper (471 mg/kg) were recorded in the studied zone, generally above the threshold limits (Table 2). Similarly, high levels of iron (4270 mg/Kg), lead (1010.25 mg/kg), zinc (693.75 mg/kg), and copper (129.00 mg/kg), notably above the critical limits, were observed in aerial parts of S. pallida evaluated at two maturity stage (Table 2). On the other hand,a low concentration of manganese was recorded (184.50 mg/kg). Phenolic contents analysis Regarding thephenolics content of S. pallida , results (Table 3) disclosed notable differences ( P<0.05 ) of total extractable phenols (TEP) and tannins (TET) content. The higher concentration was noted in the aerial parts at the vegetative stage (7.73 %DM and 6.97 %DM, respectively). Similarly, the amount of total extractable condensed tannin (ECT) was significantly ( P<0.05 ) higher at the vegetative stage (4.50 %DM) in comparison with the flowering stage (2.50 %DM) and the root part (0.55 %DM). Total flavonoid content (TFC) was higherat the vegetative stage (9.34 mg/100g DM) compared with the flowering stage (4.88 mg/100g DM) and the roots part (3.19 mg/100g DM). Antioxidant activity analysis DPPH radical scavenging activity The antioxidant properties of S. pallida extracts were assessed using DPPH free radical scavenging activity assay (Table 4). The results revealed a dose-dependent ( p<0.05 ) variation in the extract activity of Sulla evaluated at two growth stages. The (IC 50 ) value which is the concentration of the extracts needed to scavenge 50% of the initial DPPH radicals, was higher ( p<0.05 ) at the vegetative stage (IC 50 =0.126) compared with the flowering stage (IC 50 =0.416). At 1 mg/mL of the extract, S. pallida at the vegetative stage demonstrated a high percentage of free radical scavenging ability up to 81.88%, similar to that obtained by the synthetic one (BHT) (82.1%). Ferric reducing antioxidant power Likewise, the extracts of S. pallida set at three different concentrations (0.25, 0.5, and 1 mg/mL) showed high ferric reducing power (IC 50 =0.179 mg/mL) at the vegetative stage and generating (OD700) values of 0.590, 0.975 and 1.032 respectively (Table 5). These values are slightly lower ( P<0.005 ) in comparison with those recorded at the flowering stage (0.765, 1.001 and 1.121) with (IC 50 =0.112 mg/mL). However, they were much higher in comparison with the root part (0.192, 0.347 and 0.548) (IC 50 =0.964 mg/mL) or with the positive control (0.430, 0.674 and 0.961) (IC 50 =0.310 mg/mL). β-carotene bleaching test The inhibitory effect of S. pallida extract on lipid peroxidation was assessed using the beta-carotene/linoleic acid bleaching assay, which founded on the reduction of the yellow color of β-carotene due to its interaction with radicals generated during the oxidation of linoleic acid. Results show that the upper parts of S. pallida extract set to 1 mg/mL, possessed a higher antioxidant effect at vegetative (84.83%) and flowering stage (83.00%) than BHT (63.30%) with an IC 50 equal to 0.39 mg/mL and 0.56mg/mL respectively (Table 6). HPLC-ESI-MS/MS profile The phenolic compounds in the aqueous extract of S. pallida were identified through HPLC-ESI-MS/MS, detecting 38 compounds (Table 7). The findings show that 16 phenolic compounds were present with a total concentration of 2297.17 mg/kg, including 4-Hydroxy benzoic acid (401.30 mg/kg) and rutin (313.51 mg/kg), along with vanillic acid (245.26 mg/kg), gallic acid (243.44 mg/kg), and p-coumaric acid (209.29 mg/kg) were the most abundant compounds, representing over 61% of the extract (Table 8). Discussion The current data showed that S. pallida is able to maintain high symbiotic efficiency in term of nitrogen content and dry matter accumulation, similar and/or higher in comparison with other Sulla species evaluated under field conditions (Fitouri et al. 2012 ; El Yemlahi et al. 2019 ). Such findings indicate the aptitude of S. pallida to establish symbiosis withsoil microorganismsand promoting sustainable agriculture (El Yemlahi et al. 2019 ; M’saouar et al. 2020 ). In fact, earlier study revealed that the bacteria isolated from root-nodules of S. pallida , collected from the same minging site, had a great similarity to rhizobial bacteria (El Yelmlahi et al., 2019). Those strains are able to fix atmospheric nitrogen in a symbiotic relationship with the host plants, thereby enriching soil fertility and reducing the need for synthetic fertilizers. On the other hand, the field survey revealed the great capacity of S. pallida to accumulate high concentrations ofiron (Fe), lead (Pb), zinc (Zn), and copper (Cu), in its upper part. Some of those metals such as Fe, Zn, and Cu, are essential to maintain various biochemical and physiological functions. While others, such Pb, pose a significant health concern due to their toxic effects (Yang et al. 2022 ). Similar findings have been advanced by (Benhamdi et al. 2014 ; Kassa-Laouar et al. 2019 ), who reported the ability of S. pallida growing wild in the old mining sites located in Algeria, to accumulate antimony (Sb) and arsenic (As) in shoots and roots. Particular results have been attributed to the presence of heavy metal-resistant soil bacteria (Benhizia et al. 2004 ; Hamane et al. 2020 ; Oubohssaine et al. 2022 ),and ability of the plant to induce significant increases in phenolic compoundsand enzymes, with high antioxidant activities (Benhamdi et al. 2014 ; Kassa-Laouar et al. 2019 ; Usman et al. 2020 ; Oubohssaine et al. 2022 ). In fact, phenolic compounds, such as tannins, frequently play a master role in responding to various abiotic and biotic stresses (Dehghanian et al. 2022 ; Kumar et al. 2023 ). To emphasize, several chemical compounds, including flavonoidsand condensed tannins, have been identified in the genus Sulla, which confer antioxidant, anti-tumor, anti-aging, and anti-diabetic properties (Tibe et al. 2011 ; Dong et al. 2013 ; Molinu et al. 2023 ). In this study, high concentration of total extractable phenolics, mainly consisting of tannins, were measuredwhen compared with related species such as S. flexeuosa grown in different habitats (Errassi et al. 2018 ), or with those obtained for S.coronaria examined at different phonological stages (Amato et al. 2005 ), using different preservation methods (Rufino-Moya et al. 2019 ). A study carried out by (Lavid et al. 2001 ) demonstrated that waterlily (Nymphaea) rich in tannin are tolerant to Pb by directly chelating the Pb.Results indicated by (Jańczak-Pieniążek et al. 2022 ) showed that heavy metals such as (Cu) and (Pb) caused an improvementin the activity of phenylalanine ammonia-lyase (PAL) and tyrosine ammonia lyase (TAL), a key enzyme involved in the biosynthesis of phenolic compounds with an antioxidant function (Tian and Lei 2006 ). Furthermore, the results of measured phenolic compounds disclose high concentration of soluble condensed tanninin the aerial partsof S. pallida in comparison with S. flexeuosa (Errassi et al. 2018 ) or S. coronaria (Molinu et al. 2023 )over the same growth of stage. Furthermore, the results ofHPLC-ESI-MS analysis of the aerial parts of S. pallida showed a high concentration of coumaric acid with great scavenging and antioxidative properties (Roychoudhury et al. 2021 ). Additionally, the high concentration of hydroxybenzoic acid detected in this study has been reported to exhibit various biological activities including antioxidant, antibacterial, and antifungal properties (Cueva et al. 2010 ), as well as to modulate the effect of short-term drought and freezing stress on Triticum aestivum L. plants (Horváth et al. 2007 ). Studies conducted by (Yang et al. 2008 ) shed light on rutin's potent ability to scavenge free radicals, superoxide anion radicals, and hydroxyl radicals, as well as its effect on lipid peroxidation. Remarkably, significant amounts of vanillic acid and gallic acid werealso detected in the extract of Sulla pallida. The phenolic compound gallic acid has been shown to possess strong antioxidant activity and to enhance the activity of endogenous antioxidant enzymes (Singh et al. 1999 ), such as those evaluated by (Benhamdi et al. 2014 ).Vanillic acid, on the other hand, can be effective upon different environmental stresses byinducing a plant antioxidant defense, methylglyoxal detoxification system, and osmoregulation (Parvin et al. 2024 ). Equally important, the syringic acid, revealed by HPLC-ESI-MS analysis, plays a crucial role in the communication between plants and soil microorganisms (Zhou et al. 2014 ). In this regard, the findings obtained by (Hamane et al. 2020 ) highlighted the presenceof high diversity soil bacteria, with great plant growth-promoting rhizobacteria (PGPR) activities, isolated from root-nodules of S. pallida collected from the same studied site. Such compounds might serve collectively as antioxidants to detoxify ROSs generated under heavy metal stress conditions (Sakihama et al. 2002 ; Kumar et al. 2023 ). In this study, the antioxidant activities evaluation of S. pallida extract showed high radical scavenging capacity, and ferric-reducing ability, in comparison with results reported by (Hafsi et al. 2017 ) for S. carnosa grown under salinity and potassium deficiency, whichtended to be lower as the plant progressed from vegetative to flowering stage (Molinu et al. 2023 ). Conclusion The findings of the present study demonstrated a significant potential for S. pallida as a forage legume due to its strong mean DPPH radical scavenging activity (IC 50 0.271 mg.mL − 1 ), ferric reducing power (IC 50 0.145 mg.mL − 1 ), and ability to inhibit lipid peroxidation (IC 50 0.374 mg.mL − 1 ). Additionally, its great ability to accumulate high concentration of heavy metals, particularly for Pb (1610 mg/Kg DM), and to maintain remarkable symbiosis with soil microorganisms, suggests that S. pallida could be an effective plant for remediating and rehabilitating heavy metal-contaminated pastures and maintaining a consistent, long-term land use in heavy metal polluted environments.

A stock solution of \u0026beta;-carotene and linoleic acid was prepared with 2 mL of \u0026beta;-carotene (2 mg in 10 mL of chloroform) added to a tube containing 40 mg of linoleic acid and 400 mg of Tween 40. After combining the two phases, the chloroform was completely evaporated, and then 50 mL of oxygen-saturated distilled water was added to the mixture with stirring.Five milliliters of the prepared emulsion were placed into a set of tubes, each containing 0.2 mL of various concentrations of the extracts or BHT. Immediately after the emulsion was added, the absorbance was measured at 470 nm using a UV spectrophotometer.

Individual stock solutions of each analyte, at a concentration of 1000 mg L\u003csup\u003e\u0026minus;1\u003c/sup\u003e, were prepared by dissolving pure standards in HPLC-grade methanol and storing them in glass stoppered bottles at 4 \u003csup\u003e\u0026deg;\u003c/sup\u003eC, except for anthocyanins, which were stored at \u0026minus; 15 \u003csup\u003e\u0026deg;\u003c/sup\u003eC until analysis. Standard working solutions at various concentrations were prepared daily by appropriate dilution of the stock solutions with HPLC-grade methanol. Formic acid (99%) was obtained from Merck (Darmstadt, Germany). Analytical-grade hydrochloric acid (37%) was obtained from Carlo Erba Reagents (Milan, Italy). HPLC-grade methanol was supplied by Sigma-Aldrich (Milano, Italy). Deionized water (\u0026gt; 18 M\u0026Omega; cm resistivity) was further purified using a Milli-Q SP Reagent Water System (Millipore, Bedford, MA, USA). All solvents and solutions were filtered through a 0.2 \u0026mu;m polyamide filter from Sartorius Stedim (Goettingen, Germany).

In this regard, the findings obtained by (Hamane et al. \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e2020\u003c/span\u003e) highlighted the presenceof high diversity soil bacteria, with great plant growth-promoting rhizobacteria (PGPR) activities, isolated from root-nodules of \u003cem\u003eS. pallida\u003c/em\u003e collected from the same studied site.\u003c/p\u003e \u003cp\u003eSuch compounds might serve collectively as antioxidants to detoxify ROSs generated under heavy metal stress conditions (Sakihama et al. \u003cspan citationid=\"CR45\" class=\"CitationRef\"\u003e2002\u003c/span\u003e; Kumar et al. \u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e2023\u003c/span\u003e).

Results indicated that \u003cem\u003eS. pallida\u003c/em\u003e maintained high nodulation and nitrogen efficiency even at late growth stages while accumulating significant levels of Fe, Pb, Zn, and Cu in its aerial parts. Phenol content varied significantly (p\u0026lt;0.05) by phenological stage and plant part, with a high concentration of total extractable polyphenols (7.73 %DM) and tannins (6.97 %DM) recorded during the vegetative stage. Antioxidant activity, as shown by DPPH radical scavenging (IC\u003csub\u003e50\u003c/sub\u003e of 0.126 mg/mL), was comparable to the control (BHT, IC\u003csub\u003e50\u003c/sub\u003e of 0.110 mg/mL). Anti-lipid peroxidation and ferric reduction potential were highest during flowering, with values outperforming controls in some assays. HPLC-ESI-MS/MS analysis identified 38 compounds, with high levels of 4-Hydroxy benzoic acid, rutin, vanillic, gallic, and p-coumaric acids. These findings highlighted \u003cem\u003eS. pallid\u003c/em\u003e as a promising forage species for remediating heavy metal-contaminated pastures and promoting sustainable land use.\u003c/p\u003e","manuscriptTitle":"Polyphenols and antioxidant activity of Sulla pallida from mining sites of Morocco: Implication for phytoremediation of heavy metal-contaminated pastures","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-01-30 07:49:55","doi":"10.21203/rs.3.rs-5506939/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"
