【 摘 要 】

Two new phytoecdysteroids, (25S)-20,22-O-(R-ethylidene)inokosterone (1) and 20,22-O-(R-3-methoxycarbonyl)propylidene-20-hydroxyecdysone (2), 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.
