The intension of the present study was to evaluate the in vitro antioxidant activity of extracts of Saraca asoca bark. The ethanol and aqueous extracts of Saraca asoca bark were screened for in vitro antioxidant potential using models viz, 1,1-diphenly-2-picryl hydrazine (DPPH), 2,2’-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation scavenging activity, ferric reducing antioxidant power (FRAP) assay and nitric oxide free radical scavenging activity (NOS) reducing power ability using standard procedures. The extracts of Saraca asoca bark exhibited strong antioxidant activity with DPPH, ABTS, FRAP and NOS assays. The radical scavenging effect was found to increase with increasing concentrations. The IC50 values of ethanolic and aqueous extracts of in all models viz, DPPH, ABTS, FRAP and NOS were found to be 80.09 µg/ml, 38.76 µg/ml, 63.73μg/ml, 9.94 µg/ml and 73.6 µg/ml, 77.15 µg/ml, 51.12μg/ml, 24.86 µg/ml, respectively. The results show that there was an increase in the reducing power of the plant extract as the concentration of the extract increases. It can be accomplished that the extracts of Saraca asoca bark is a potential source of natural antioxidants.
