The African oil bean (Pentaclethra macrophylla) seed was analyzed for its proximate composition. The seed oil was also analyzed for mineral content and physicochemical characteristics. Proximate analysis revealed that the percentage crude protein, crude fibre, moisture and carbohydrate were 9.31, 21.66, 39.05 and 38.95%, respectively. The percentage oil content was 47.90% while the ash content was 3.27%. Results of minerals analysis showed that calcium had the highest concentration of all the elements analyzed and were found to be of the order: Ca > Mg > Pb > Fe > Mn > P > Cu. The low iodine value of the seed oil showed that it can be classified as non-drying oil and thus not suitable for paint and polish production. However, the low acid and free fatty acid values suggest its utilization as edible oil.
