GC-MS Analysis of Fixed Oil from Sudanese Maerua pseudopetalosa (Glig and Ben.)De Wolf Roots

Abstract

In view of lack of literature data on the constituents of medicinal plants used in Sudanese ethno medicine , the present study was designed to identify the constituents of the fixed oil from roots of Sudanese Maerua pseudopetalosa.This important plant is used traditionally in Sudanese ethno medicine. GC-MS analysis revealed the presence of the following major constituents: oleic acid(24.49%),9,12-octadecadienoic methyl ester((10.64%),9-octadecenoic acid-1,2,3-propanetriyl ester(9.58%), γsitosterol(8.60%), cyclododecyne(6.08%). Beside γ-sitosterol, some sterols were also detected, but as minor constituents. These are : β-sitosterol acetate(0.15%), cholest-5-en-3-ol-(3β)-propanoate(0.41%),stigmasta-5,22dien-3-ol acetate(0.78%) and compesterol(0.40%).
