Studies on the Constituents of Asclepiadaceae Plants. XXXVIII. Component of Cynanchum caudatum MAX. Structure of Glycocaudatin

Abstract

A new 5, 6α-glycolic compound, glycocaudatin, isolated from Cynanchum caudatum, in addition to glycocynanchogenine and 12β-O-cinnamoyl-20-O-acetyl-glycosarcostin, was identical with the derivative obtained in a good yield via the epoxidation of caudatin, which had been isolated from the same plant.
