A new steroidal glycoside, 2α,3β-(22R)-trihydroxycholestan-6-one-22-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranoside, was isolated from the whole plants of Lepisorus ussuriensis, together with α-ecdysone and ecdysterone. Their structures were determined by means of spectroscopic and chemical methods.
