Resumo: In Brazil, popular knowledge about medicinal plants is the reason for several investigations involving various plant species. Among the studies conducted with plant extracts, there is a special interest in antioxidant activity, which acts by inhibiting and/or decreasing the effects triggered by free radicals and oxidizing compounds. From this perspective, the present work evaluated the antioxidant action of ethanolic extracts species: Pereiro (Aspidosperma pyrifolium Mart), Juazeiro (Ziziphus joazeiro Mart), Catingueira (Caesalpinia pyramidalis Tui), Black Jurema (Mimosa tenuiflora Willd) and Ameixa Selvagem (Ximenia americana L.) natives to the Alto Oeste Potiguar region of Rio Grande do Norte. The leaves and stems were collected at Barro Vermelho site, in São Francisco do Oeste (RN), to obtain the extracts. They were then subjected to antioxidant activity tests using the DPPH free radical. All samples analyzed showed a good percentage of antioxidant activity in their different concentrations, highlighting the EEFA, which had the highest percentage of antioxidant activity at the lowest concentration. Thus, it is suggested that from these data, these species may have medicinal purpose as popular knowledge.

Entre los estudios realizados con extractos vegetables, hay un interés especial en la actividad antioxidante, que actúa inhibiendo y/o disminuyendo los efectos desencadenados por los radicales libres y los compuestos oxidantes. Así, este trabajo evaluó la acción antioxidante de los extractos etanólicos de las especies: Pereiro (Aspidosperma pyrifolium Mart), Juazeiro (Ziziphus joazeiro Mart), Catingueira (Caesalpinia pyramidalis Tui), Jurema Preta (Mimosa tenuiflora Willd) y Ameixa Selvagem (Ximenia americana L.) nativas de la región del Alto Oeste Potiguar de Rio Grande do Norte. Las hojas y tallos fueron recolectados en el sitio de Barro Vermelho, ciudad de São Francisco do Oeste (RN), para obtener los extractos. Luego fueron sometidos a pruebas de actividad antioxidante utilizando el radical libre DPPH. Todas las muestras analizadas mostraron un buen porcentaje de actividad antioxidante en sus diferentes concentraciones, destacando el EEFA, que tenía el mayor porcentaje de actividad antioxidante en la concentración más baja. Por lo tanto, se sugiere que a partir de estos datos, estas especies pueden tener fines medicinales como afirma el conocimiento popular.No Brasil o conhecimento popular acerca das plantas com ações medicinais é motivo para diversas investigações envolvendo variadas espécies vegetais. Dentre os estudos realizados com extratos de plantas, há um interesse especial na atividade antioxidante, que atua inibindo e/ou diminuindo os efeitos desencadeados pelos radicais livres e compostos oxidantes. Diante dessa perspectiva, o presente trabalho avaliou a ação antioxidante de extratos etanólicos das espécies: Pereiro (Aspidosperma pyrifolium Mart), Juazeiro (Ziziphus joazeiro Mart), Catingueira (Caesalpinia pyramidalis Tui), Jurema Preta (Mimosa tenuiflora Willd) e Ameixa Selvagem (Ximenia americana L.) nativas da região do Alto Oeste Potiguar, no Rio Grande do Norte. A coleta das folhas e caules foi realizada no sítio Barro Vermelho, município de São Francisco do Oeste (RN), para obtenção dos extratos. Em seguida, eles foram submetidos a testes de atividade antioxidante utilizando o radical livre DPPH. Todas as amostras analisadas demonstraram uma boa porcentagem de atividade antioxidante em suas diferentes concentrações, destacando-se o EEFA, que teve o maior percentual de atividade antioxidante na menor concentração. Assim, sugere-se que a partir desses dados, essas espécies podem apresentar finalidade medicinal conforme conhecimento popular.Research, Society and Development2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/157810.33448/rsd-v9i1.1578Research, Society and Development; Vol. 9 No. 1; e48911578Research, Society and Development; Vol. 9 Núm. 1; e48911578Research, Society and Development; v. 9 n. 1; e489115782525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/1578/1433Copyright (c) 2019 Pamela Rayssa Diogenes Fernandes, Ayla Márcia Cordeiro Bizerrainfo:eu-repo/semantics/openAccessFernandes, Pamela Rayssa DiogenesBizerra, Ayla Márcia Cordeiro2020-08-19T03:04:08Zoai:ojs.pkp.sfu.ca:article/1578Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:32.936394Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
