Free Radical Scavenging Potency of Five Date Varieties at Different Stages by Using DPPH Assay
Samples of date fruit was collected from Khairpur Mir’s district and examined for antioxidant activity, for this purpose extract was prepared in different diluents like Methanol+Water (50:50), methanol and water by using DPPH assay. It was observed from data that all the extract have impressive antioxidant ability against free radicals. Among them solution have more ability to ramp the free radicals. From data, it was concluded that Gajar Wari is more active as it possess lowest IC50 value (20.022 µg/mL in Methanol) then rest of other date varieties at final stage in solution as well as Aseel variety also possesses lowest IC50 value (18.33 µg/mL), there for have more ability against free radicals in methanol at second stage.
