Abstract:
A new pregnane glycoside, marsdeoreophiside B was isolated from the stems of Marsdenia oreophila (Asclepiadeaece). The structure was elucidated by means of chemical and spectrometric analysis as 12-O-cinnamyldihydrosarcostin-3-O-beta-D-glucopyranosyl (1-->4)-O-3-O-methyl-6-deoxy-beta-D-allopyranosyl(1-->4)-O-beta-D- oleandropyranosyl (1-->4)-O-beta-D-cymaropyranoside. It showed significant antifertility activity in rats.
