Abstract:

This study was carried out to evaluate the nutritional composition of leaves of Mallotus oppositifolius, Sterculia trangacantha, Chrysophyllum delevoyi, Dialium guineense. Leaves were collected from their natural habitat in Ado Ekiti. The result obtained from the study revealed that the samples contained a considerable amount of proximate constituents (Moisture, Fat, Crude fibre, Ash, Protein and Carbohydrate), anti-nutrient (phytates, oxalates saponins, tannins), minerals (Na, Ca, Mg, Zn, Fe), vitamins (A, and C) in varying proportion. The result on proximate composition showed that Chrysophyllum delevoyi had the highest values of protein (22.35%), fat (5.63%) and moisture content (10.38%). Mallotus oppositifolius recorded the highest value of fibre (6.28%), while Dialium guineese had the highest values of carbohydrate (60.44%) and Ash (10.10%). Chrysophyllum delevoyi had the highest value of Mg (122.80). Mallotus oppositifolius had the highest values of Fe (35.08) and Ca (2011.00) mg/100g. Sterculia trangacantha had the highest values of Na (72.27 mg) and Zn (20.28 mg). Mallotus oppositifolius had the highest value of vitamin A (0.69), while Chrysophyllum delevoyi had the highest value of vitamin C (18.35) μg/g. Mallotus oppositifolius had the highest values of oxalates (87.22 mg), tannins (1221.00 mg) and saponins (22.35 mg), while Chrysophyllum delevoyi had the highest values of phytates (64.33mg). From this study, it can be concluded that consumption of these tree species in several forms, either as food or as condiments to supplement minerals, vitamins, protein in the human diet, especially among the rural dwellers with low income, might help to reduce malnutrition rates in our society.
