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 H 2 O 2 , O 2 • ˉ, HOCl, ONOOˉ and ROO • . 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. Sabará peel (SFP) deactivated HOCl with IC 50 9.24 μg. mL −1 ; Paulista seed (PF) deactivated O 2 • ˉ with IC 50 16.15 μg. mL −1 ; Coroada seed (CFP) deactivated ONOOˉ with IC 50 3.84 μg. mL −1 ; the peel of CFP deactivated ONOOˉ with IC 50 5.88 μg. mL −1 ; the peel of SFP deactivated the ROO • at 918.16 μmol TE. g −1 ; and Sabará seed deactivated H 2 O 2 with 49.11% inhibition at a concentration of 125 μg. mL −1 of extract. These results demonstrate the high antioxidant potential of this fruit, indicating that it could be extremely beneficial to human health.
