Abstract
AbstractA new megastigmane glycoside, (3S,5R,6R,9S)‐6,9‐epoxiionane‐3,5‐diol 3‐O‐β‐primeveroside (1) together with 7 compounds (2–8) were isolated from Achyranthes aspera L. The chemical structures were elucidated through 1D‐, 2D‐ NMR, and HR‐ESI‐MS experiment. The absolute configuration of 1 was determined using combination of the experimental and theoretical calculation of CD spectra. Compounds 2 and 7 were reported for the first time from the genus Achyranthes.
