Phytochemical investigation of Caralluma wissmannii O. Schwart

ABSTRACT The chromatographic investigation of Caralluma wissmannii O. Schwart. led to the isolation of two new pregnane glycosides (5, 6) and five known compounds (1-4, 7). The new pregnane glycosides were identified using spectral means (NMR and MS) as 12-tigiloyl-tayloron 3β-D-thevetopyranosyl-(14)-β-D-cymaropyranosyl-(14)-β-D-cymaropyranoside 5, 12-tigiloyl-tayloron 3β-D-thevetopyranosyl-(14)-β-D-cymaropyranoside 6. The known compounds were identified as 3,4-seco-lup-20(29)-en-3-oic acid methyl ester 1, lupeol 2, stigmasterol 3, β-sitosterol 4, and luteolin 3',4'-di-O-β-D-glucopyranoside 7. This is the first report on the phytochemical investigation of C. wissmannii
