Abstract

Oil was extracted from Chrysophyllum albidum seed using petroleum ether as solvent. The yield of the oil was found to be 4.9%. The result of characterization of the oil extract showed that it has iodine value of 163.3mg, Saponification value of 90.71mg, Acid value of 19.70 mg, Percentage Free Fatty Acid of 9.90% and Dirt content of 0.23%. The specific gravity of the oil at 250C and its content was found to be 0.8269 and 10.00% respectively. The color analysis gave Red, Yellow, Blue and Neutral to be 1, 1, 2, 2, 2, 1 and 0,0 respectively. Thus the oil was found to be a drying oil. The Fatty Acid Profile of the oil was also determined with the aid of gas liquid chromatography used fatty acids in methyl esters and was found to have Oleic Acid (C18:1) as the predominant fatty acid having an area of 10.10125%.  It was also found to contain Alpha Linoleic Acid (omega-3) and Linoleic Acid (omega-6) which are essential to the human body but cannot be synthesized by its metabolic processes.
