ABSTRACT

This research work aim at investigating the chemical constituents present in the Plukenetia conophora stem bark in order to ascertain its usefulness as a medicament and food supplement. The proximate analysis results: 51 % moisture, 3.24 % fat, 27.42 % fibre, 6.29 % protein, 4.26 % Ash and 7.79 % carbohydrate. The mineral analysis revealed the following: K, 5750 mg/kg, Na, 5040 mg/kg, Ca, 21750 mg/kg, Mg, 1658.75 mg/kg, Fe, 9460 mg/kg, Zn, 55.30 mg/kg, Mn, 68.50 mg/kg, Cu, 20.65 mg/kg. Vitamin composition results showed: Thiamine (B1) 0.21 μg/100g, riboflavin (B2) 0.15 μg/100g, niacin (B3), 0.27 μg/100g, cyanocobalamin (B12) , 0.14 μg/100g, ascorbic acid (C) 0.003 μg/100g, tocopherol (E), 0.79 μg/100g. The phytochemical screening and analysis shows; alkaloids, 2.890 mg/kg, saponins, 1.260 mg/kg, tannins, 0.340 mg/kg, and anthraquinones, 0.064 mg/kg. The study shows that Plukenetia conophorum stem barks could be a potential food supplement and useful source of drug formulation.
