Madian Al-Salem, Ziad Noufal

Abstract


Phytochemical analysis of the CHCl3 and methanol fractions of Nitraria Retusa L. has led to the isolation and identification of a new sterol; Retusasterol and another known compound;  β- sitosterol glucoside. The structure elucidation of  both compounds was based on spectroscopy data IR, MS, 1H and 13C – NMR, DEPT (90,135), HMQS, COSY and HMBC.

Keywords: Nitraria Retusa. L. , Retusasterol , β-Sitosterol , Sterol.
