The research work was carried out to ascertain the viability of seeds of an African star apple as a source of oil for industrial use. Oils were extracted from dried seeds of African star apple using n-hexane by Soxhlet extraction method. A comprehensive range of physicochemical properties, namely: free fatty acid, peroxide value, saponification value, iodine value, and specific gravity were determined. The characterization of the oil was done according to the methods described by the Association of Official Analytical Chemist. The percentage yield of the oil was 2.5%, dark yellow in colour and liquid at room temperature. Saponification value of the oil was 51.45, Iodine value was 19.20, Peroxide value stood at 1.78, and Specific gravity was 0.91. The low yield and values of saponification and iodine show that, the oil is not viable for industrial use. February - April 2016 Copyright © 2016 i-manager publications.
