The Antidiabetic, Antioxidant properties in vitro of Moringa oleifera Flowers extracts grown in Sahara of Algeria

Moringa oleifera Flowers extracts grown in Algerian Sahara were evaluated antidiabetic and antioxidant activity by means using divers established in vitro systems, such as α-Amylase inhibitory assay, DPPH radical scavenging assay, Phosphomolybdenum assay (PM) and Ferric reducing power assay (FRAP). Moreover, the total content of phenols, flavonoids and tannins from (MFCE) and various fractions was measured using colorimetric methods. Results demonstrated that TPC varied between 95,50  0,42 and 10, 49  0,053 mg GAE/g WE, while TFC was between 17,00  0, 011 and 2,47  0,014 mg GAE/g WE, In this study TTC ranged between 2,96 0,016 and 1,30 0, 014 mg GAE/g WE. All capacities of DPPH radical scavenging, Phosphomolybdenum (PM) and Ferric reducing power (FRAP) were found best in (MFEF) (IC50= 0,159± 0,004mg/ml, AEAC = 42.37 ± 0.28 mM and AEAC =104.05±0.41 mM respectively). Add to this (MFEF) showed the highest α-amylase inhibitory activity (I= 38,92 %).
