Twenty new pregnane glycosides were obtained from the roots of Asclepias syriaca L. (Asclepiadaceae). These glycosides were confirmed to contain ikemagenin, 12-O-nicotinoyllineolon, 5alpha,6-dihydroikemagenin, and 12-O-tigloylisolineolon, as their aglycones, using both spectroscopic and chemical methods.
