Two new cardenolide diglycosides, named oxystelmoside and oxystelmine, were isolated from the dried roots of Oxystelma esculentum.On the basis of chemical and spectroscopic evidence their structures were established as uzarigenin 3-O-β-D-xylopyranosyl(1->4)-O-β-D-digitalopyranoside and periplogenin 3-O-6-deoxy-β-D-glucopyranosyl(1->4)-α-D-digitalopyranoside. Key Word Index - Oxystelma esculentum; Asclepiadaceae; roots; oxystelmoside; oxystelmine; steroid; cardenolide glycoside.

The thermal degradation of cardenolide glycosides consisting of different sugar moieties and aglycones was examined.On simple heating, the sugar - aglycone linkage of cardenolide glycosides having 2,6-dideoxy sugar moieties is readily cleaved, to afford their genuine aglycones.On the contrary, cardenolide glycosides possessing 6-deoxy sugar moieties are resistant to the degradative reaction.Besides the fission of the glycosidic linkages, some interesting reactions also took place.The pyrolyzed products were isolated by chromatography, and the structures were elucidated by spectroscopic evidence.
