Mediterranean Blue Flowers with a Scent of Cannabis

The aromatic herb Plectranthus neochilus with a cannabis smell, widely used in folk medicine, has become the subject of a study of its essential oils of flowers and leaves. GC-MS analysis revealed a unique composition, the oils of flowers, the main component of which is 2-methyl-1-butene, its concentration exceeds 87 percent. On the one hand, this is very unusual data, although, on the other hand, it is known that 2-methyl-1-butene can be a product of thermal decomposition of 1,1-dimethyl-cyclopropane. However from a microbiological point of view, 2-methyl-1-butene can be a product of bacterial reduction of isoprene by a mixture of Comamonas sp. and Acetobacterium wieringae bacteria. This issue is extremely interesting and requires further careful study, although a preliminary discussion is given in the discussion of this phenomenon. Analysis of the oil from the leaves showed that the main products are α-thujene and α-pinene, the content of which exceeds 75 percent. According to a detailed analysis of the species Plectranthus, it was found that this species is a producer of volatile metabolites containing cyclopropane and cyclobutane rings. It is assumed that the compounds of essential oils containing cyclopropane and cyclobutane rings may be the main biologically active substances in this species or genus of plants. Data on the biological activity of the main identified compounds of this aromatic plant are presented..
