Mustazi Jafri and B.K. Mehta

Abstract

The chemical examination of benzene extract of the stem bark of B. monosperma revealed the presence of steroids for isolation of steroids the stem bark of B. monosperma. dried powder of stem bark of B. monosperma was subjected to hot extraction with benzene. The benzene extract was subjected to column chromatography. Isolated compounds were purified and crystallized by chloroform: methnol. After isolation and purification afforded white crystalline substance which was subjected to physical , chemical and spectral analysis and identified by IR, 1H-NMR, 13C-NMR and higher resoluation mass spectra. The compound identified as β-sitosterol(1) and stigma sterol(2).

Keywords: Butea monosperma ; stem bark; ? –sitosterol , stigmasterol.
