Nutrient potentials of two lesser known leafy vegetables (Vitex doniana L. and Sesamum indicum L.)

Two lesser known vegetables, Vitex doniana L. and Sesamum indicum L. consumed by the rural dwellers in Savannah region of Nigeria were subjected to chemical analyses in an effort to determine their nutrient potentials. Results showed that V. doniana and S. indicum contained (g/100 g dry weight) moisture (8.04, 10.26), crude protein (8.75, 18.37), crude fiber (15.58, 11.75), crude fat (5.10, 6.14), ash (7.92, 11.04) and carbohydrate (70.20, 54.21), respectively. Ascorbic acid contents (mg/100 g) of the vegetables were 24.60 and 53.80 while nutritive values (Kcal/g) were 361.70 and 345.55, respectively. Both vegetables were also good sources of calcium (3.36, 2.00 g/100 g), potassium (1.13, 2.04 g/100 g) and iron (0.12, 0.67 mg/kg). Copper, chromium, nickel and zinc were found in trace amount for S. indicum whereas these elements were present below the detection limit for V. doniana leaves. The levels of anti -nutrients in the leaves were found lower than the permissible limits and could not have any adverse nutritional effect on human. Thus, the vegetables could complement the conventional ones in enhancing food security and sustainable livelihood.
