In this study we investigate the antioxidant, anti-inflammatory, and antidiabetic activities of ethanolic leaves extracts of three selected varieties of Phoenyx dactylifera L. namely: “Ghars”, “Deglet Nour” and “Hamraya”. The assessment of the antioxidant potential of crude leaves extracts, using superoxide anions inhibition, DPPH and total antioxidant activity essays, was carried out. Furthermore, the anti-inflammatory properties of the extracts were determined by measuring the inhibition of nitric oxide (NO) production. Moreover, the antidiabetic effect was evaluated by inhibition of α-amylase enzymes. The total phenolic content measured by Folin-ciocalteu method was as well conducted. The raw leaves extracts of the selected varieties was found to contain a high content of total phenolic content (342.45 mg GAE/gDW for GE) and therefore exhibited a higher antioxidant activity and inhibitory effect of radicals scavenging activity against DPPH and superoxide anion (IC50 = 7.44 μg/mL and 39.11 μg/mL respectively). The three varieties exhibited significant inhibition nitric oxide using in-vitro assay (IC50 = 240.28 μg/mL for GE). The extracts also displayed high inhibition actions against α-amylase enzymes. The results suggest that the leaves of the three selected varieties of Phoenyx dactylifera can be considered as a good source of natural antioxidant and anti-inflammation drugs as well as potent antidiabetic medicine.
