A new megastigmane glycoside, (3 S ,5 R ,6 R ,9 S )‐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 .
