Leaves of Pterocarpus mildbraedii obtained from Samaru and sabo was analyzed for proximate constituents and elemental compositions. It content for samaru and sabo samples respectively: (10.94 ± 0.083, 10.81±0.070%) ash, (9.35 ± 0.031, 9.19±0.070%) moisture, (21.00±0.19, 21.27±0.030%) crude protein, (5.91 ± 0.110%, 6.00±0.020) crude lipid, (8.15±0.230, 8.11±0.130%) crude fibre and (44.65±0.655, 44.57±0.352%) carbohydrate. Minerals like zinc (30.70, 30.90mg/kg) and potassium (1049, 1050.50mg/kg) are predominantly abundant, manganese (3.27, 3.24mg/kg) is present in less appreciable amount while no level of Arsenic was detected in both samples and this values conform with the daily recommended dietary allowance for the minerals as being reported by FAO/WHO (2012). The study established that Pterocarpus mildbraedii (oha leaf) contains high amount of vital minerals and nutrients (e.g. potassium, carbohydrates, protein) needed for a healthy diet. Its high protein and carbohydrate content further eulogize the inestimable nutritional values of the plant. It can therefore be affirm that P. mildbraedii is a potential industrial raw material for food formulation and drug development.
