Abstract:- The phytochemical and biochemical compositions of African walnut (Tetracarpidum conophorum) were determined for two samples of the variety-the boiled and mashed wet nuts, and the dried powdered nuts. Results of phytochemical analysis revealed the presence of the following expressed as percentage. For the mashed wet nuts: Saponins (8.37±0.1); flavonoids (3.20 ±0.2); phenols (1.90±0.1), tannins (0.51±0.0) and alkaloids (0.41±0.1). For the dried and powdered variety, the results are- Saponins (5.03±0.2); flavonoids (2.70 ±0.1), tannins (0.45±0.1), phenols (1.51±0.1) and alkaloids (0.350±0.1). Proximate compositional analysis expressed as percentage shows the following results: moisture (45.01±0.1)WM,(2.88±0.02)DP; Crude fat (13.81±0.01) WM, (32.21±0.01) DP; Crude protein (18.75±0.01) WM, (13.72±0.02 ) DP;CHO (18.43±0.1) WM,(46.38±0.2) DP; Crude fiber (1.95±02) WM,(1.72±0.02 ) DP; Ash (1.91±0.01) WM,(3.11±0.01) DP, FE( 273.01±0.1) WM, (530.29±0.02) DP. The values of the vitamins are expressed in mg/ml as shownbelow:VitaminA is expressed in µg/ml(1283.33±1.18)DP, (285.60±0.2)WM;Vit.C (14.80±0.02)DP,(17.57±0.01)WM;riboflavin (0.12±0.02)DP,(0.12±0.02)WM;Thiamine(B1) (0.20±0.01)DP,(0.12±0.01)WM; Niacin(2.81±0.01)DP,(2.91±0.01).The mineral composition of the nut is very outstanding and not significantly affected by the processing methods. The values of the minerals are shown as follows: Mg (0.36±0.01) DP.,(0.31±0.01)WM; Ca (2.10±0.2)DP, (1.88±0.1)WM; P(0.35±0.01)DP, (0.36±0.01)WM and others. The phytochemical and nutrient compositions of this tropical nut are expository and depicts the role of the seeds in nutrition and health.
