Abstract
C-nor-D-homo-homologues of cannogenin and uzarigenin glycosides were isolated along with known cardenolide glycosides from the frozen fresh leaves of Thevetia neriifolia. A bisdesmosidic tetraoside of 3 beta,14,21-trihydroxy-5 beta,14 beta-pregnan-20-one was also obtained from the polar fraction and the structure established.
