Determination of Proximate and Mineral Elements Compositions in the Bark of Dacryodes edulis (G.Don) H.J. Lam

摘要

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.
