Six phytoecdysterones have been isolated from the n -BuOH portion of Cucubalus baccifer L., a Chinese folk medicinal plant. Their structures were elucidated as ecdysterone (1), 24(28)-ecdysterone (2), 22-deoxyecdysterone (3), 25-hydroxypanuosterone (4), rubrosterone (5) and 2,22-dideoxyecdysterone 3β-O-β- D -glucopyranoside (6) respectively on the basis of spectroscopic and chemical methods. Among them compound 6 was a new phytoecdysterone glycoside and 1-5 were first obtained from this plant.
