%X Background: This study evaluates the radical-scavenging activity of five plants used as food and medicines in the northeastern region of Brazil. Materials and Methods: Spectrophotometric analysis of the plants¡ä ethanol extracts was carried out. The antioxidant activity was determined by the DPPH (2,2-diphenyl-1 picrylhydrazyl) test. The antioxidant capacity was measured using ascorbic acid as a positive control. Results: All tested plant extracts showed an antioxidant activity, but the highest activity was observed with the extracts of Momordica charantia and Eugenia jambolana. Conclusions: Therefore, these species must be studied as a putative source of products for use in the prevention and treatment of diseases in which oxidants or free radicals are implicated.
