Abstract
The MeOH extract from dried roots of Oxypetalum caeruleum (Apocynaceae, formerly known as Asclepiadaceae) plants yielded twenty new pregnane glycosides, some of which had a new 12,20-epoxy type aglycone. The structures of these compounds were established using NMR, MS spectroscopic analysis and chemical evidence.
