Abstract:
The roots of Cynanchum caudatum M. (Asclepiadaceae) afforded eleven new pregnane glycosides which had cynanchogenin, caudatin, 12-O-benzoyllineolon and 12-O-benzoyldeacylmetaplexigenin as the aglycone moiety and 2,6-dideoxy-3-O-methylhexopyranoses as component sugars. The structures of these compounds were elucidated by spectroscopic methods and from chemical evidence.
