Twenty new pregnane glycosides were isolated from the whole plant of Caralluma negevensis. Their structures were elucidated by extensive spectroscopic methods including 1D-(H-1, C-13, C-13 DEPT, TOCSY, ROESY) and 2D-NMR experiments (DQF-COSY, HSQC, HMBC, HOHAHA) as well as ESI-MS analysis. Pregnane glycosides were tested for their cytotoxic and genotoxic activity.

Abstract
Twenty new pregnane glycosides were isolated from the whole plant of Caralluma negevensis. Their structures were elucidated by extensive spectroscopic methods including 1D-(H-1, C-13, C-13 DEPT, TOCSY, ROESY) and 2D-NMR experiments (DQF-COSY, HSQC, HMBC, HOHAHA) as well as ESI-MS analysis. Pregnane glycosides were tested for their cytotoxic and genotoxic activity.File in questo prodotto:
