Composition in Mineral Elements of the Traditional Vegetables Leaves of Cuervea isangiensis (de wild.) N.hallé in Congo-Brazzaville

In this study, the proximate composition and physicochemical analyses were carried out on the vegetables-leaves of Cuervea isangiensis (De Wild.) N. Hallé. The results showed that the rate of mineral elements depends on the place of harvest, so for the harvested samples : locality 1 ( forest 1): Magnesium 104 ± 0,00 mg/ 100g; Phosphor 725,50 ± 39, 50 mg / 100g; Potassium 970 ± 0,00mg/ 100g; Iron 11, 53 ± 0,03mg/ 100g ; Calcium 2,21 ± 0,00 mg/ 100g; for the locality 2 ( forest 2): Magnesium 164,50 ± 2,50 mg/ 100g; Phosphor 1093 ± 79 mg/ 100g; Potassium 820 ± 0,00mg/100g ; Iron 11,34± 0,03 mg/ 100g; Calcium3,06 ± 0,00mg/100g. In conclusion, these values compared fluently to those of the 10 vegetables-leaves clear soups show the leaves of Cuervea isangiensis (De Wild.) N. Hallé are rich particularly in minerals Potassium, Phosphor, Magnesium and Iron. These leaves present a big interest on the nutritional plan in the struggle against the deficiencies in micronutrients.
