Leaf Epicuticular Wax Chemical Composition of Morettia phillaeana (Del.) DC. From Sudan

Abstract

      Morettia phillaeana was analyzed for its chemical composition of surface epicuticular wax. The constituents were extracted from the leaves by using n-hexane solvent, and were identified by using Gas chromatography-mass spectroscopy (GC/MS). The major components were hydrocarbons (74.15%), fatty acids, methyl ester (15.73%). and phytosterol (5.47%). Twelve components out of 29 were characterized representing 90.98% of total components. The most abundant compounds were tetracontane (57.74%), Octacosane (6.58%), β-sitoterol (5.47%), Hexadecanoic acid, methyl ester (3.81%), pentacosane (3.77%) and 2-methylhexacosane (3.43%).
