%X Oroxylum indicum is a medicinal plant species known in Gujarat by the common name Syonakh. The free radical scavenging potential of the Oroxylum indicum was studied by using different antioxidant models of screening.  In-vitro antioxidant activity of petroleum ether, ethyl acetate and n-butanol extract of stem and root bark of Oroxylum indicum was determined by ABTS radical cation decolorization assay, Scavenging of nitric oxide radical, Reduction of ferric ions by ortho- phenanthroline colour method, inhibition of lipid peroxide formation. Ascorbic acid was used as standard and positive control for both the analysis. All the analysis was made with the use of UV-Visible Spectrophotometer (Systronics 117, Japan). The n-butanol extracts of stem and root bark of Oroxylum indicum shown very significant scavenging activity as compared to standard. Hence, it is suggested that Oroxylum indicum showed significant antioxidant activity.
