OBJECTIVE To investigate the steroid constituents of Achyranthes bientata Bl.. METHODS Solvent extraction and column chromatography were used to isolate the non-alkaloid constituent, and physico-chemical constants and spectroscopic analysis were employed for structural elucidation.RESULTS Three steroid constituents were isolated and their structures were elucidated to be 2β,3β,5β,14α,20β,22α,25-heptahydroxy-cholest-7-en-6-one (Polypodine B,1);2β,3β,14α,20β,22α,25-hexahydroxy-cholest-7-en-6-one(2);2β,3β,20β,22α,25-pentahydroxy-cholesta-8,14-dien-6-one(3),respectively. CONCLUSION Compound 3 is a new compound.
