RESUMO -(Plantas medicinais usadas pelas populações indígenas Kaiowá e Guarani na Reserva de Caarapó, Mato Grosso do Sul, Brasil). Estudo etnobotânico realizado com a população indígena Kaiowá/Guarani na Reserva de Caarapó (Mato Grosso do Sul, Brasil) mostrou que 34 espécies vegetais, distribuídas em 22 famílias, têm propriedades medicinais e são utilizadas para o tratamento de diversas patologias. As informações obtidas foram: nome local em Português e em Guarani, indicações terapêuticas, preparação e a parte da planta utilizada. As principais plantas medicinais são usadas pela população indígena no tratamento de gripes e resfriados, dores abdominais, febres, reumatismos e para o tratamento de feridas.

ABSTRACT -(Medicinal plants used by the Kaiowá and Guarani indigenous populations in the CaarapóReserve, Mato Grosso do Sul, Brazil). This ethnobotanical survey carried out with the Kaiowá and Guarani populations in the Caarapó Reserve (Mato Grosso do Sul, Brazil) showed that 34 plant species of 22 families with medicinal properties, are used for treating diverse pathologies. Local names in Portuguese and Guarani are provided, along with therapeutic indications, modes of preparation, and a description of the plant parts used. These folk-medicine plants have been mostly used for the treatment of influenza, abdominal pain, fever and rheumatism, and for wound healing.
RESUMO: O objetivo do presente trabalho foi realizar um levantamento etnofarmacológico das principais espécies vegetais comercializadas no Mercado Municipal de Campo Grande (MS).essencialmente de plantas medicinais para os cuidados básicos de saúde (Akerele, 1992). Ainda hoje nas regiões mais pobres do Brasil e até mesmo nas grandes cidades, plantas medicinais são comercializadas em feiras livres, mercados populares e encontradas em quintais residenciais
ABSTRACT: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 (IC 50 <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.
