New Oxypregnane Glycosides from
Caralluma penicillata

Abstract

The ether fraction of the defatted ethanol extract of the aerial parts of Caralluma penicillata (defl) M. E. Br. (Asclepiadaceae) yielded four new oxypregnane glycosides, penicillosides D-G. The structures of the isolated compounds were established by different spectroscopic methods.

Key words

Caralluma penicillata - Asclepiadaceae - oxypregnane glycosides - penicillosides D-G - NMR
