Abstract:

Oil from Irvingia wombulu was extracted, purified and characterized by Soxhlet Extractor. Standard methods were used for the determination of the physiological indices, while the Fatty acid components were determined using the Gas chromatographic technique. The percentage of pure fat after extraction was 60%. The physiochemical analysis revealed the following: Relative density (0.82), PH (6.22), Saponification value (178.39mgKOH-1), unsaponifiable matters (0.85%), Iodine value (2.54/100g Fat), Peroxide value (0.96mgEqKg-1). Gas-Liquid Chromatography revealed that the major Fatty acids were: C14:O (48.93%), C12:O(32.37%), C16:0 (7.95%), C10:O (0.93%), C18:0 (0.75%) and C18:1(4.58%). The result of this study is indicative that the Irvingia wombulu oil contains high concentration of unsaturated fatty acids and thus may not be heart friendly.
