vitro and in vivo antioxidant potential of hydromethanolic extract of Phoenix dactylijera fruits

The present study was aimed at investigating the antioxidant activities of the hydromethanolic extract of Phoenix dactylifera (HEPD) fruit (Arecaceae). The antioxidant activities of extract have been evaluated by using a range of in vitro assays and in vivo hepatoprotective model. In case of in vitro studies the IC50 values were found to be 160, 1400, 1115, 1050 μg/ml in DPPH, nitric oxide, superoxide, hydroxyl radical scavenging assays, respectively. In case of in vivo studies the levels of liver enzymatic, non-enzymatic systems [serum glutamate oxalo-acetate transaminases (SGOT), serum glutamate pyruvate transaminases (SGPT), alkaline phosphatase (ALP), total bilirubin, total protein, catalas
