Abstract: Three new phytoecdysteroid compounds, named niuxixinsterone A (1), B (2) and C (3) with acetal functions in the side-chain were isolated from Achyranthes bidentata Bl. The structures were established as (20R,22R,24S)-20-O,22-O-(5′-hydroxymethyl)-furfurylidene-2β,3β,14α,25-tetrahydroxy-5β-ergost-7-en-6-one (1), (20R,22R)-20-O,22-O-(5′-hydroxymethyl)-furfurylidene-2β,3β,25-trihydroxy-14β-methyl-18-nor-5β-cholesta-7,12-dien-6-one (2) and (20R,22R,25R)-20-O,22-O-(5′-hydroxymethyl)-furfurylidene-2β, 3β,5β,14α,26-pentahydroxycholest-7-en-6-one (3) by means of spectroscopic evidence.
