Abstract : Proximate composition, amino acid profile and antinutrients contents of mango seed were investigated. The results of proximate analysis show that mango seed contains (10.06±0.12%) crude protein, (14.80±0.13%) oil, (2.62±0.02%) ash, (2.40±0.01%) crude fibre, (70.12±1.34%) carbohydrate and energy content (453.92±4.32 KJ/100 g). The results also show that mango seed is very rich in glutamate (13.00 g/100 g of protein) while methionine has the lowest value (1.04 g/100 g of protein). Among the essential amino acids, leucine has the highest value (8.40 g/100 g of protein). This is followed by arginine which has the value of 5.17 g/100 g of protein. The results of antinutrient analysis show that mango contains alkaloid (0.01±0.0 mg/100 g), tannins (1.03±0.01 mg/100 g), phytate (1.44±0.01 mg/100 g), cyanide (0 mg/100 g), saponin (0.04±0 mg/100 g) and oxalate (1.49±0.01 mg/100 g). Its trypsin inhibitor activity was found to be (18.42±2.54 TIU/mg protein). The vitamin analysis showed that mango seed contained 15.27 (IU) vitamin A; (1.30 mg/100 g) vitamin E; (0.59 mg/100 g) Vitamin K; (0.08 mg/100 g) Vitamin B1; (0.03 mg/100 g) Vitamin B2; (0.19 mg/100 g) Vitamin B6; (0.12 mg/100 g) Vitamin B12 and (0.56 mg/100 g) Vitamin C. The result of mineral analysis showed that mango seed contained sodium (21.0 mg/100 g), potassium (22.3 mg/100 g), calcium (111.3 mg/100 g), magnesium (94.8 mg/100 g), iron (11.9 mg/100 g), zinc, (1.1 mg/100 g) and copper (0.1 mg/100 g). Therefore, mango seed is a nutritional promising seed.
