Abstract: Jabuticaba has a high concentration of phenolic compounds, which have a significant antioxidant capacity. Methodologies have been developed to evaluate the ability of plant extracts to fight free radicals such as H2O2, O-2(center dot)-, HOCl, ONOO- and ROO center dot. Thus, the capacity of deactivation of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in peel and seed extracts of five varieties of jabuticaba was evaluated. Sabara peel (SFP) deactivated HOCl with IC50 9.24g. mL(-1); Paulista seed (PF) deactivated O-2(center dot)- with IC50 16.15g. mL(-1); Coroada seed (CFP) deactivated ONOO- with IC50 3.84g. mL(-1); the peel of CFP deactivated ONOO- with IC50 5.88g. mL(-1); the peel of SFP deactivated the ROO center dot at 918.16mol TE. g(-1); and Sabara seed deactivated H2O2 with 49.11% inhibition at a concentration of 125g. mL(-1) of extract. These results demonstrate the high antioxidant potential of this fruit, indicating that it could be extremely beneficial to human health
