Abstract: The mineral and proximate compositions were analyzed in wet and dry samples of Mangifera indica and Persea americana seeds using standard methods of analyses. These determinations were determined on dry extract basis. The results revealed: ash 9.05-9.68%, crude protein 5.65-6.63%, crude fat 5.68-8.28%, crude fibre 5.31-6.75%, carbohydrate 63.26-64.25% and energy 334.64-350.04 Kcal in dry samples while wet sample produced, ash 7.20-11.28%, crude protein 4.35-10.65%, crude fat 4.21-6.42%, crude fibre 4.38-8.30%, carbohydrate 33.92-40.15 and energy 216.17-255.78%. As expected moisture content was high in the wet than dry sample. The mean values showed that Mangifera indica seed was higher in moisture, crude protein and crude fibre while ash, crude fat, carbohydrate and energy were higher in Persea americana seeds. Mineral contents showed that Zn, Cu, Pb, Ca and Mg were more concentrated in the wet sample than in the dry sample of Mangifera indica, while in Persea amercana, Zn, Fe, Mn, Pb, Ca and Mg were better concentrated in the wet sample. However, Cd, Cr and Al were not detected in both seed samples. The results are compared to those of other common seeds and it is hoped that it would add to the existing nutritional data on fruits and seeds.
