Chemical Evaluation of the Proximate, Minerals, Vitamins and Phytochemical Analysis of Danielle Oliveri Stem Bark
Daniellia oliveri stem bark (DSP) is one of potential medicinal plants loaded with several bioactive chemicals/phytochemicals, vitamins, vitamins and other nutrients. In view of these potential, it can serve as an alternative to antibiotics, thus bridging the gap between food safety and livestock production. Hence, the present study was carried out to evaluate the proximate, minerals, vitamins and phytochemical composition of DSP. Proximate analysis of DSP revealed the presence of moisture (6.25 ± 1.00 %), dry matter (93.75 ± 0.21%), crude protein (6.07 ± 0.45%), ether extract (1.03 ± 0.65%), ash (9.11 ± 0.33%), carbohydrate (21.09 ± 0.25%) and energy (488.73 ± 11.2 KJ/100g). Calcium, phosphorus, potassium, sodium, iron, zinc, magnesium, selenium and manganese were the minerals present at (71.33 mg/100g), (45.08 mg/100g), (8.17 mg/100g), (25.11 mg/100g), (3.57 mg/100g), (10.22 mg/100g), (20.93 mg/100g), (1.45 mg/100g) and (1.33 mg/100g) respectively. Vitamin analysis showed that it contained β-carotene (1.97 mg/100g), thiamine (0.74 mg/100g), riboflavin (0.42 mg/100g), niacin (0.30 mg/100g), pyridoxine (0.22 mg/100g), cyanocobalamin (0.18mg/100g), ascorbic acid (6.84 mg/100g), calciferol (0.13 mg/100g) and phytonadione (0.10 mg/100g). Phytochemical screening showed that DPS is abundant in flavonoids (9.44%) followed by alkaloids (6.83%), hydrolysable tannins (4.57 %), phenol (3.46 %), terpenoids (2.11%), saponins (2.10 %), phytates (1.88 %), condensed tannin (1.17 %), oxalates (1.03 %) and steroids (0.97 %). It was concluded DSP contain substances with numerous therapeutic potentials capable of treating various ailments and ensuring normal physiological functions of the body.
