Abstract

Determination of proximate, mineral ele ments compositions, total antioxidant capacity and total phenolic contents of the bark of Dacryodes edulis (G. Don) H.J. L am was carried out. Proximate study revealed that the bark is adequate in nutrients and minerals. Macro nutrient like protein Carbohydrates was determined with a content level of 58 ±0.16mg/kg. Other macro nutrients were also relatively high in content level.While crude Protein had a content level of 61.7 3±0.11mg/kg, crude Lipid had a content level of 48.56±0.20mg/kg. Proximate analysis for crude Fibre, Vitamin C, Ash, a nd Moisture also revealed their contents levels to be 61.66±0.92mg /kg, 24.01±0.16mg/kg, 52.37±0.38mg/kg and 14.56±0.1 mg/kg, respectively. The existence of essential minerals and thei r contents levels analysed showed that Dacryodes edulis contains sodium (Na; 7.20±0.04) mg/kg, potassium (K; 2.57±0. 25) mg/kg and Iron (Fe; 17.76±0.02) mg/kg, calcium (C ; 83.24±0.89)mg/kg, Zinc (Zn; 3.65±0.08)mg/kg, and manganese (M n; 241.28±) mg/kg, respectively, values range that are n on-lethal, therapeutic and idea for the maintenance of good health except for Manganese that was on the very high side. Dacryod esedulisbark was found to be also very rich in anti-oxidan ts and phenols, with total anti-oxidant capacity of 103.0 2±0.62mgVce and phenol (total) content of 112.95±0.56GAE100-1re spectively.
