F. Abe et al., THEVETIA .3. GLYCOSIDES OF 19-FORMYLTHEVETIOGENIN AND 5-ALPHA-THEVETIOGENIN FROM THEVETIA-NERIIFOLIA, Phytochemistry, 37(5), 1994, pp. 1429-1432
C-nor-D-homo-homologues of cannogenin and uzarigenin glycosides were i
solated 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 th
e polar fraction and the structure established.
