AB: Six non-conventional leafy vegetables consumed largely by the rural populace of Nigeria were analysed for mineral composition. Mineral contents appeared to be dependent on the type of vegetables. Amaranthus spinosus and Adansonia digitata leaves contained the highest level of Fe (38.4 mg/100 g and 30.6 mg/100 g dry weight, respectively). These values were low compared with those for common Nigerian vegetables but higher than those for other food sources. All the vegetables contained high levels of Ca compared with common vegetables. Microelement content of the leaves varied appreciably. Zn content was highest in Moringa oleifera, Adansonia digitata and Cassia tora leaves (25.5, 22.4 and 20.9 mg/100 g dry weight, respectively) while Mn content was comparatively higher in Colocasia esculenta. The concentrations of the minerals in the vegetables per serving portion are presented and these values indicate that the local vegetables could be valuable and important contributors in the diets of the rural and urban people of Nigeria. Mean daily intakes of P, Mg, Ca, Fe, Cu and Zn were lower than recommended dietary allowances (RDA). However, Mn daily intake did not differ from the RDA value.
