Mineral Composition of Some Selected Vegetables Sold in Mile 3 Market, Port Harcourt Rivers State Nigeria
Abstract
Five green leafy vegetables (Water leaf, Pumpkn leaf, Scent Leaf and Bitter leaf) commonly consumed in Port Harcourt, Rivers State Nigeria, were purchased from Mile 3 market and analysed for mineral composition. The presence of Na, Zn, K, Fe, Mg and Ca were analysed using Atomic Absorption Spectrophotometry, Versenate EDTA complexometric method, and by Flame Photometery. The mean values obtained for Na ranged from 8.686±0.343 to 10.540±0.378 mg/Kg, Zn ranged from 0.438±0.069 to 0.863±0.064 mg/Kg, K ranged from 3.928±0.692 to 11.943±0.635 mg/Kg, Fe ranged from 1.250±0.231 to 5.546±0.307 mg/Kg, Mg ranged from 5.111±0.447 to 8.739±0.489 mg/Kg and Ca ranged from 6.019±0.367 to 10.910±0.344 mg/Kg. Each of the leafy vegetables investigated contained mineral constituents which were different when compared with other vegetables. Green leafy vegetables are a good source of macro/micro nutrients.
