Phytochemical investigation of Mimosa pigra leaves, a sensitive species.
Mimosa pigra L. is an invasive species that grows with related species called M. pudica L. M. pudica is a dietary supplement, marketing in the United States, with a claim of supporting the immune system. It is known that M. pudica has been misidentified with M. pigra L. As part of our ongoing research endeavors to identify the chemical constituents of broadly consumed herbal supplements or their adulterants, a detailed phytochemical investigation of M. pigra was undertaken. As a result, seven specialized metabolites, including six flavonoid-O-glycosides were isolated from the leaves of M. pigra. The isolated chemical constituents in this study could be used as chemical markers to differentiate M. pigra-based raw materials in various finished products, including the quality of dietary supplements claimed to contain M. pudica.
