Abstract— The aim of this study is to contribute to a better valorization of the mucilaginous food plants (MFPs) by the content determination in essential minerals, also to evaluate the nutritive contributions from the consumption.
Thus different edible parts constituted of leaves, fruits, flowers, calyx and kernels of nine mucilaginous food plants of Ivorian flora have been analyzed. It’s about I. gabonensis, I. wombolu, C. olitorius, the varieties tomi and koto of A. esculentus, B. buonopozense, A. digitata, M. arboreus and B. mannii. The analysis of the macroelements (K, P, S, Ca and Na) gave the following contents: potassium (0.73±0.02-4.53±0.03 g/100g DM), Phosphorus (0.40±0.03-1.70±0.04 g/100g DM), sulphur (0.1±0.04-0.75±0.03 g/100g DM), Calcium (0.06±0.01-4.54±0.06 g /100g DM) and sodium (0.06±0.01 and 0.32±0.02 g /100g DM). The plants provided the microelements (Mg, Fe, Cu, Mn and Zn) contents following: magnesium (0.15±0.01-1.36±0.25 g/100g DM), Iron (6.73×10-3±2.84-55.94×10-3±6.96 g/100g DM), copper (4.96×10-3±2.07-54.04×10-3±4.63 g/100g DM). The kernels of I. wombolu and the leaves of M. arboreus provided 7.38×10-3±6.79 and 27.67×10-3±28.9 g/100g DM respectively in Zinc. The daily quantities of mucilaginous food plants consumed are consisted between 0.1 g/day and 0.7 g/day. This consumption provided to Ivorian adult of 70 kg the daily contributions estimated following: potassium (1.5-27.70 mg/day), calcium (0.1-31.80 mg/day), magnesium (1.1-25.5 mg/day), iron (0.12-1.18 mg/day). The leaves of M. arboreus provided the best daily contributions (0.19 mg/day) in Zinc. The leaves and the flowers among the parts investigated gave on the whole, the biggest daily contributions. They contributed for the majority of minerals, between 1% and 4% of the organism needs.
