Abstract

The proximate, mineral and amino acid compositions of two different seeds belonging to different families; Brachystegia eurycoma harms and Pipper guineense schum and thonn were investigated. The proximate analysis revealed the values of carbohydrate, fat, crude protein, crude fibre, ash and moisture contents present to be 53.57%, 4.49%, 8.75%, 17.20%, 5% and 10.60%; 46.57%, 17.30%, 9.33%, 4.20%, 9.90% and 12.70% respectively. Minerals present are Ca (0.64), Na (0.09), K (0.25), Fe (0.111), Mg (0.05) and Mn (0.066) for Brachystegia eurycoma harms and Ca (0.42), K (0.81), Na (0.32), Ph (0.25), Zn (0.081), Mg (0.04) and Mn(0.098) in ppm. The anti-nutrient constituents of both seeds revealed the presence of tannins, phytate and cyanide at relatively low concentrations. Phytochemical screening also analysed for the seeds were all positive except glycosides and anthraquinones which are negative in Brachystegia eurycoma harms and Pipper guineense schum and thonn respectively. This shows that both seeds have therapeutic roles in living organisms. The amino acid (AA) analysis revealed that AA was more concentrated in B. eurycoma harms with the total value of 42.28g/100g than 38.78g/100g of P. guineense schum and thonn. The former also exceeded the later in total EAA by difference of 4.67g/100g. The P-PER and pI both seeds were 2.59; 2.54 and 2.61; 2.18, while the limiting AA was Met + Cys (0.40) and Ile (0.28) for B. eurycoma harms and P. Guineense schum and thonn respectively.
