A cardenolide tetraglycoside from Oxystelma esculentum.
A new cardenolide tetraglycoside, oxyline, was isolated from the dried roots of Oxystelma esculentum. On the basis of chemical and spectroscopic evidence the structure of oxyline was established as 3-epi-uzarigenin-3-O-beta-D-cymaropyranosyl-(1----4)-O-beta- D-thevetopyranosyl-(1----4)-O-beta-D-cymaropyranosyl- (1----4)-O-beta-D-digitoxopyranoside.
