Proximate, mineral, vitamins and phytochemical compositions of nine accessions of Piper nigrum leaves and fruits were investigated in order to assess their nutritional value. The result showed that all the nutritional traits of the leaves and fruits of these accessions varied significantly (P<0.01). the result of the proximate composition showed that the leaves contained protein (17.46 -20.30%), ash (10.30-12.94%), carbohydrate (42,32-46.17%), fat (3.59-4.04%), fibre (10.64-13.62%) and energy (273.68-295.67 kcal/100g) while the fruits contained protein (8.44 -9.18%), carbohydrate (51.37-53.74%), fate (12.77-15.05%), fibre (5.13.5.50% and energy (361.65 -384.18 kcal/100g). Elemental analysis r e- vealed that the calcium and magnesium content of the accession was high while zinc and iron was moderate. These a c- cessions of Piper nigrum were high in vitamin C but had low levels of thiamine, riboflavin and niacin while it was o b- served that higher phytochemicals occurred in the fruits than in the leaves.
