Abstract
The oil from the aril portion of the pulp organ of Blighia sapida obtained from Akoka area of Lagos State was
investigated· for some fatty acid composition and physicochemical properties. The oil substance was extracted by cold maceration in re-dis till ed ethyl acetate solvent alone and in combination with ·pure butanol for between 4 and 8 days.
The pure oil substance was recovered by (air drying for 24 -48 hrs under cool atmosphere) and then in the oven with inbuilt fan set at 35°C for between 2 and 5 days. the physicochemical properties of the investigated included: Saponification Value (SV) 196.7mg KOH/g: Peroxide value (PV) 7.73 m E. q. O2/kg sample; Acid value (AV), 2.24mg KOH/g; Jodine Value (IV) 44.559 I2 /1OOg sample; Specific gravity (SG) 0.9; Refractive index (RI) 1.45 Õ Free fatty acid (FFA) 1.13% as oleic acid; Ester value (EV) 195.5mg KOH/g. The GC-MS analysis within operational condltions
showed the free fatty of the present oil sample had a predominance of oleic acid (55.65%) followed by palmitic acid (25_92%); stearic acid (3.90%) and vaccinic acid (3.4 % ). The presence of multiple free fatty acids was further attested to by the Fourier Transform Infrared absorption signals.
