Eugenia operculata Roxb. also known as Cleistocalyx operculatus Roxb., or Syzygium nervosum belongs to the myrtaceae family is a well known perennial tree, commonly known as tom heinou in Manipur, India. The purpose of this study was to elucidate the antioxidant capacities of E.operculata. The ethanol and aqueous extracts were used in the present study. The extracts were screened for the presence of phytochemical constituents. Antioxidant properties were determined by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and reducing power method.IC50 values of ethanol and aqueous extracts were found to be 52.96±0.94 and 41.73±0.4 for DPPH assay. Reducing assay reveals dose dependent reducing power. The extract showed potent antioxidant activity when compared with standard ascorbic acid and gallic acid. Total phenolic content for ethanol and aqueous extracts were found to be 58.6 and 88.1mg/gm GAE.The ethanol and aqueous extracts of E.operculta posses significant antioxidant activity.
