Resumo: | ABSTRACT: The use of plants for medicinal purposes has accompanied humans since the first centuries, their use for a long time represented the only source of medicinal material. Native to the Caatinga biome, Tabebuia caraíba is popularly used for its expectorant and antipyretic action. Thus, the present work aims to analyze the phytochemical extract composition of the species, as well as its antioxidant activity (DPPH and ABTS methods). It was possible to obtain data on the chemical characteristics of three parts (branches, leaves and trunk) of the species, with the presence of flavonoids, catechins, anthocyanidins, triterpenoids, steroids, phenols, tannins and leucoanthocinidines. In the anthocyanins analysis, the leaves obtained the highest result, 5.040 mg/100g of the evaluated sample. The tannins quantification showed a higher result for leaves, with 1506 ppm. In capturing the DPPH radical, a better capacity was obtained for the aqueous extract of the bark, with an IC50 of 112.50 ppm. For the ABTS radical capture methodology, the bark extract in ethanol reached the result of 739.64 µM trolox/g, a high value compared to other studies that used this methodology. The use of two methodologies proved to be effective when none of the hexane extracts showed activity for the DPPH methodology, whereas for the ABTS methodology, it was possible to detect the activity. The tests performed showed important results for the development of studies in the research area in question. KEYWORDS: Medicinal plants, antioxidants, anthocyanins. |

Nativa do bioma Caatinga, a Tabebuia caraíba é popularmente utilizada por sua ação expectorante e antitérmica. Assim, o presente trabalho tem o objetivo de analisar a composição fitoquímica de extratos da espécie, bem como sua atividade antioxidante (métodos DPPH e ABTS). Foi possível obter dados sobre as características químicas de três partes (galhos, folhas e tronco) da espécie, sendo observada a presença de flavonoides, catequinas, antocianidinas, triterpenóides, esteroide, fenóis, taninos, leucoantocinidinas em seus extratos. Na análise de antocianinas, as folhas obtiveram o maior resultado, 5,040 mg/100g da amostra avaliada. Já na quantificação de taninos, observou-se maior resultado para folhas, com um teor de 1506 ppm. Na captura do radical DPPH, obteve-se melhor capacidade para o extrato aquoso da casca, com CI50 de 112,50 ppm. Para captura de radical ABTS, o extrato da casca em etanol alcançou o resultado de 739,64 µM trolox/g, um valor alto comparado a outros trabalhos que utilizaram esta metodologia. O uso de duas metodologias se mostrou eficaz quando, nenhum extrato hexânico apresentou atividade para a metodologia de DPPH, já para a metodologia de ABTS, foi possível detectar atividade desses mesmos extratos. Os testes realizados apresentaram resultados importantes para desenvolvimento dos estudos na área de pesquisa em questão.
