Chemistry

An extract of A. propinquus called TA-65 may activate telomerase, extending the lengths of the shortest telomeres which protect the terminal DNA at the ends of all chromosomes.[9] It contains the saponin cycloastragenol. Constituents of the roots (Radix Astragali) include polysaccharides, triterpenoids (astragalosides)[10] as well as isoflavones (including kumatakenin, calycosin and formononetin) along with their glycosides and malonates.[11]

Toxicology

While several other species of Astragalus are known to cause severe poisonings in livestock due to indolizine alkaloids, aliphatic nitro compounds, and accumulated selenium,[12] none of these constituents have been detected in the medicinal species Astragalus membranaceus used in dietary supplements and TCM preparations.[13]
