Astragaloside
From Wikipedia, the free encyclopedia

Astragalosides are a series of related chemical compounds isolated from Astragalus membranaceus.[1]
Also known as astrasieversianin, AS-IV, astraversianin XIV, or cyclosiversioside F, it is a white powder with a melting point of 284 °C–285 °C (Wang et al., 1987). Its molecular formula is C41H68O14, and its theoretically accurate molecular weight is 784.4609.[2]
Research on astragaloside IV, TA-65 in particular, has found that it has the potential to activate the telomerase enzyme in humans to lengthen telomeres at the ends of human chromosomes.[3]
