Several vegetables are used in food preparation to improve the aroma, taste, appearance with less attention on the nutrient and anti-nutrient content. This study investigated the proximate, vitamins, minerals and anti-nutrients profile of Beilschmiedia manni seed and Combretum racemosum leaf. Proximate composition, vitamins, mineral analysis and anti-nutrient profile were determined using standard procedures. The proximate analysis revealed that C. racemosum contained high crude protein (19.18%), crude fat (22.20%) and energy value (449.11 kJ) but low carbohydrate (43.15%) compared to B. mannii with the high carbohydrate (64.25%) content. Phytochemical screening revealed the presence of active phytochemicals in both samples. Thiamine, riboflavin and niacin were significantly (p < 0.05) high in B. mannii compared to C. racemosum. The level of macro minerals in B. mannii seeds and C. racemosum leaves was in the order of K > Ph > Na > Mg > Ca. Beilschmiedia mannii seeds and C. racemosum leaves respectively contained 45.00 mg/100 g and 163.00 mg/100 g oxalate, 70.00 mg/100 g and 113.00 mg/100 g phytate, 58.00 mg/100 g and 209.00 mg/100 g of tannin. This study has revealed that B. mannii seeds and C. racemosum leaves are potential sources of essential nutrients, phytochemicals and could play important role in food enrichment, formulation of dietary supplements and in disease managements.
