Astragalosides are a series of related chemical compounds isolated from Astragalus membranaceus.
Also known as astrasieversianin, AS-IV, astraversianin XIV, or cyclosiversioside F, it is a white powder with a melting point of 284 ðCâÂÂ285 ðC (Wang et al., 1987). Its molecular formula is C<sub>41</sub>H<sub>68</sub>O<sub>14</sub>, and its theoretically accurate molecular weight is 784.4609.
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.
