The review integrates information on the component composition and biological activity of some Astragalus L. (Fabaceae) species from studies reported over the past 5–7 years. The aerial and underground parts of 34 Astragalus species contain triterpene saponins, flavonoids, polysacharides, tannins, free organic acids, higher fatty acids, vitamins, trace elements, and other constituents. Among the Astragalus species, A. membranaceus (Fisch.) Bunge is the best studied in terms of component composition and biological activity. Anti-inflammatory, immunomodulatory, antioxidant, anticancer, cardioprotective, and hepathoprotective activities have been experimentally detected in total bioactive substances, fractions, and individual compounds extracted from various parts of A. membranaceus and A. membranaceus var. mongholicus in vitro and in vivo. The composition and biological effects of other Astragalus species are still poorly understood. The review summarizes the recent advances in studying new compounds extracted from Astragalus species and their biological activities. [ABSTRACT FROM AUTHOR] |
