In vitro antioxidant potential of different solvent extracts of Naregamia alata

Total phenolics, tannins, flavonoids and the antioxidative properties of the traditionally used medicinal plant Naregamia alata Wight. & Arn. were assessed. The hot water extract contained higher levels of total phenolics, tannins and flavonoids. The extracts were subjected to assess their potential antioxidant activities using various in vitro systems such as DPPH•, ABTS•+, FRAP, β-carotene linoleic acid bleaching system, phosphomolybdenum reduction and Fe2+ chelation. It is concluded that N. alata may serve as a potential source of natural antioxidants capable of offering protection against free-radical mediated damages.Colegio de Farmacéuticos de la Provincia de Buenos Aire
