The classification of fatty acids of lipids from seeds of Persea grattisima Miller and Chrysophyllum albidum G. Don.

Abstract

The fatty acids from seed lipids of Persea grattisima and Chrysophyllum albidum were studied inorder to identify, classify and to ascertain the suitability of these lipids for edible and industrial purposes. Lipids were extracted with chloroform-methanol (2:1) and quantified with Gas Liquid chromatography. Gas liquid chromatographic analyses of Persea grattisima and Chrysophyllum albidum seed lipid extracts indicated that cholesteryl heptadecanoate (C17.0), 1,3 dipalmitin 2-stearin (16.0, C18.0), triolein (C18.1), trilinolein (C18.2), trilinolenin (18.3), and tristearin (C18.0) were the major fatty acids present in Persea grattisima while cholesteryl myristate (C14.O), cholesteryl palmitate (C16.0), and triolein (C18.1) were the fatty acids present in Chrysophyllum albidum. These studies show that Persea grattisima and Chrysophyllum albidum have high oil content hence can be classified as oil seeds and the fatty-acids of seed lipids could be potential sources of industrial oil.
