Studies on the Constituents of Asclepiadaceae Plants. IX. On the Components of Cynanchum caudatum MAX

Abstract

The stems and leaves of Cynanchum caudatum MAX. were proved to contain a glycoside mixture. The sugar portion of the glycoside was found to be D-cymarose by paper partition chromatogoraphy comparing with an authentic specimen.
Six kinds of aglycone, such as deacylcynanchogenin, sarcostin, crystal, m. p.215-220°, and other 3 spots were found by paper partition chromatography. They were isolated by adsorption chromatography using alumina, and partition chromatography over Celite as a carrier.
