Pregnane glycosides from Caralluma russeliana.
The aerial parts of Caralluma russeliana yielded four new pregnane glycosides, russeliosides A-D (1-4), in addition to a known flavone glycoside, luteolin 4'-O-beta-D-neohesperidoside. The structures of compounds 1-4 were elucidated using a combination of spectroscopic methods.
