Abstract Cola parchycarpa (monkey cola) has been one of the underutilized Tropical plant in Tropical African sub regions. It is among some of the valuable fruit species whose potentials have not been fully realized. In recent times, work has been carried out on the proximate and phytochemical properties of the cola but no result on the activities or potency of the oil. The values obtained from the physical properties of the oil from Cola parchycarpa were: Refractive Index (1.5550 ), Specific gravity (0.9127 ), Viscosity (47.8236 , Oil yield (11.5000 and the colour is deep yellow respectively. The chemical properties were Acid value (mg/g) (102.1020±0.01), free fatty acid (28.7928±0.01), Saponification value (mg/g) (152.5920±0.02), Iodine value (mg/g) (61.4196±0.01) and Peroxide value (mmol/kg) (46.4196±0.02) respectively. The Fatty acid composition of oil from the sample revealed Palmitic Acid (C16:0) (32.5410) as the highest saturated fatty acid present, Stearic Acid (C18:0) (2.6871), Myristic Acid (C14:0) (1.1902), Arachidic Acid (C20:0) (1.6281) had value greater than one while other saturated fatty acids present were less than one. Polyunsaturated fatty acid present were Linoleic Acid (C18:2) (17.1689), Linolenic Acid (C18:3) (2.0694) and Arachidonic acid (C20:4) (0.3722) respectively. The highest monounsaturated present were Oleic Acid (C18:1) (42.4471) while other values for monounsaturated present like Palmitoleic Acid (C16:1) and Erucic Acid (C22:1) were less than one. The antibacterial activity revealed that the oil from Cola parchycarpa was susceptible to Escherichia Coli (2.00 0.01), Staphylococcus aureus (5.00 0.02) (Klebsiella pneumonia (2.00 0.01) and Pseudomonas Spp (1.00 0.01) and resistant to Proteus. Though the cola is of low yield, but the oil had great health benefits and good industrial and pharmaceutical applications.
