Abstract:
Twenty-six new acylated-oxypregnane glycosides were obtained along with three known cardenolide glycosides from the roots of Asclepias curassavica (Asclepiadaceae). The new compounds were confirmed to contain 12-O-benzoylsarcostin, 12-O-benzoyldeacylmetaplexigenin, kidjolanin, and 12-O-benzoyltayloron, and one new acylated-oxypregnane, 12-O-(E)-cinnamoyltayloron, as their aglycones, using both spectroscopic and chemical methods.
