Abstract
Biochemical studies with a view to assess the nutritional potentials of Anisopus mannii were carried out by evaluating the proximate composition, mineral elements and anti- nutritional content of the plant. The results showed that the total oxalates, free cyanides, tannins and total cyanides were found to be present at 0.70±0.5, 6.50±0.41, 10.55±0.01 and 12.41±7.19%, respectively. However, concentration of phytate was very low (0.017±0.00%). Proximate compositions of the plant showed a rich source of cmde protein (8.40±0.17%), fats (8.67±0.63%), carbohydrates (72.57±0.68%) and total ash (10.36±0.22%). The plant was also found to contain the following essential minerals: potassium (1700 mg/lOO g), calcium (1280 mg/100 g), iron (156 mg/100 g), vanadium (102 mg/100 g), chromium (53.90 mg/100 g), zinc (0.874 mg/100 g), copper (1.43 mg/100 g) and manganese (36.60 mg/100 g). The results of this research indicated that Anisopus mannii has nutritional qualities that could provide the users with additional nutrients for enhanced curative process of ill health.
