The proximate composition (moisture, ash, crude fat, crude protein, fibre content, and carbohydrate), the mineral compositions (Na, K, P, Ca, Mg, Fe and Zn); and anti-nutrients (oxalate, phytate, hydrocyanic acid and tannin) were determined in Gnetum africanum (Afang) and Heinsia crinita (Atama). The percent crude protein, crude fat, moisture content, carbohydrate values (38.40%, 24.69%, 84.70% and 10 48%) of Heinsia crinita were significantly (p<0.05) higher than values obtained from Gnetum africanum (26.50%, 14.34%, 63.78% and 6.75%) respectively. The concentrations of mineral elements phosphorus, potassium, iron, magnesium and calcium were (1.25%, 1.64%, 3.05%, 2.39% and 2.22%) respectively in Heinsia crinita and (0.14%, 0.10%, 1.15% 0.92% and 0.45%) respectively. The values of mineral elements were significantly higher (p<0.05) higher in Heinsia crinita than Gnetum africanum. The percent hydrogen cyanide, phytate, oxalate, and tannin values (3.51%, 6.12%, 24.4% and 2.80%) of Gnetum africanum were significantly (p<0.05) higher than values obtained from Heinsia crinita (1.20%, 3.51%, 10.12% and 0.78%) respectively The results showed that Heinsia crinita had more nutritive values than Gnetum africanum which are needed for a variety of cellular functions in humans, and which could reduce the problem of protein energy malnutrition (PEM).
