EVALUATION OF ANTI OXIDANT ACTIVITY OF ETHANOLIC ROOT EXTRACT OF ALBIZIA LEBBECK (L.) BENTH

Abstract

Albizia lebbeck (L.) Benth belonging to the family Fabaceae is a medicinal plant associated with diverse biological activities like antimicrobial, analgesic, anti-inflammatory, anti diarrhoeal, immunomodulatory, anti-arthritic, anti-ashmatic, anticonvulsant nootropic etc. reported by various researchers. In the presented study ethanolic root extract of the plant was evaluated for its in-vitro anti-oxidant potential by DPPH free radical scavenging activity, Nitric oxide scavenging activity, Hydrogen peroxide scavenging activity and reducing power assay taking ascorbic acid as the standard. The extract exhibited antioxidant activity possessing IC50 values (H2O2 Scavenging Activity), 345.94(Nitric Oxide Scavenging Activity), 945.76 (DPPH Free Radical Scavenging Activity). In ferric reducing assay the absorbance were found to increase with increase in concentration of the extract revealing reducing power.
