title: In vitro antioxidant activity of species collected in Paraná.
abstract: Hydroalcoholic extracts of 10 medicinally used species collected from the area covered by a reservoir due to a dam built for the Salto Caxias Hydro-electric power plant in the State of Paraná, Southern Brazil, and Casearia sylvestris, were investigated for their potential antioxidant activity against DPPH (1,1-diphenyl-2-picrylhydrazyl) free radicals and by the phosphomolybdenum method. The extract of Bauhinia microstachya was found to be the most potent in both models.
