ABSTRACT

The general objective of this work is to determine the nutritive and antioxidant properties of the leaf powders of Apium graveolens, Adansonia digitata, Talinum Triangulare and Moringa oleifera for their use in the treatment of chronic diseases. The plant material used in this work consists of leaves of Apium graveolens, Adansonia digitata and Moringa oleifera. The analyzes focused on the moisture content, dry matter, ash content, crude protein content, total sugar content, reducing sugar content, lipid content, determination of the fiber content raw materials, the dosage of minerals (sodium, potassium, phosphorus, iron, magnesium, calcium and zinc), the content of carotenoids, the content of beta-carotene, lycopenes and vitamin A. Phenolic compounds, flavonoids and tannins were extracted and quantified. The antioxidant activity of leaf powders was also evaluated. The results showed that the leaf powders contain contents varying from 21.2 to 28.6 mg/100 g of dry matter. Among the leaf powders studied, the greatest antioxidant activity was found in Adansonia digitata leaf powder (89.3 µg/ml) with the lowest effective concentration (IC50) being 3.4 µg/ml.
