ABSTRACT
Two new phytoecdysteroids, (25S)-20,22-O-(R-ethylidene)inokosterone and 20,22-O-(R-3-methoxycarbonyl)propylidene-20-hydroxyecdysone, together with six known phytoecdysteroids 3-8 were isolated from the roots of Achyranthes bidentata Blume. The new structures were established on the basis of spectroscopic studies and chemical evidences. The absolute configuration at C-25 in the structure of known compound 3 was determined by chemical and spectroscopic means.
