Resumo: | The purpose of this study was to screen the antioxidant activity of medicinal plant extracts from the Brazilian cerrado, through other methods than the total phenolic content and its correlation with the antioxidant activity. Ethanolic extracts of ten species were evaluated through three antioxidant assays, in vitro, including 2,2-diphenyl-1-picrylhydrazyl (DPPH), total antioxidant activity and reducing power; and by using the Folin-Ciocalteu method the total phenolic content was determined. Ethanolic extracts of Stryphnodendron obovatum, Cecropia pachystachya and Duguetia furfuraceae showed strong antioxidant activity (IC50<5 µg mL-1) in the DPPH free radical scavenging assay; the species Vernonia phosphorea, Hymenaea stignocarpa and Jacaranda ulei may also be highlighted. These results were confirmed in the assays of total antioxidant capacity and reducing power. The extracts of S. obovatum and V. phosphorea showed an abundant phenolic content; therefore, the phenolic content may play a role in the antioxidant activity. These two species, traditionally used in Brazil, showed great power in these assay systems and may be a promising source for the development of natural antioxidants and future candidates for phytochemical and pharmacological studies in related diseases. |
