title: 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.
