Objective: In the present investigation, phytochemical screening was performed, the in vitro antioxidant and photoprotective activity of Tabebuia serratifolia bark extracts was determined. Methods: The bark extracts were obtained by maceration technique using acetone and ethanol as solvents. Standard chemical staining and/or precipitation tests were used for preliminary phytochemical analysis. Antioxidant activity was evaluated through the 2,2'-diphenyl-1-picrylhydrazyl (DPPH) assay. The photoprotective effect was established by the Mansur spectrophotometric method. Results:Phytochemical analysis showed that the extracts possess alkaloids, flavonoids, phenolic compounds, quinones, coumarins, triterpenes and steroids. The total content of phenolic compounds and flavonoids for the acetone extract (TSA) was 71.54 mg gallic acid equivalents/g extract and 8.80 mg quercetin equivalents/g extract, respectively, while for the ethanol extract (TSE) it was 65.70 mg gallic acid equivalents/g extract and 8.19 mg quercetin equivalents/g extract. The mean inhibitory concentration (CI50) value of the extracts was 80.91 μg/mL for TSA and 84.25 μg/mL for TSE. The extracts had an average sun protection factor, for TSA it was 12.92 and for TSE it was 7.67. Conclusion: The results showed that Tabebuia serratifolia extracts possess a great variety of chemical compounds with antioxidant and photoprotective activity.

Objetivo: En la presente investigación se realizó el tamizaje fitoquímico, se determinó la actividad antioxidante y fotoprotectora in vitro de los extractos de la corteza de Tabebuia serratifolia. Métodos: Los extractos de la corteza fueron obtenidos mediante la técnica de maceración usando como solventes acetona y etanol. Para el análisis fitoquímico preliminar se utilizaron pruebas químicas estándar de coloración y/o precipitación. La actividad antioxidante se evaluó a través del ensayo de 2,2´-difenil-1-picrilhidrazilo (DPPH). El efecto fotoprotector se estableció por el método espectrofotométrico de Mansur. Resultados: El análisis fitoquímico demostró que los extractos poseen alcaloides, flavonoides, compuestos fenólicos, quinonas, cumarinas, triterpenos y esteroides. El contenido total de compuestos fenólicos y flavonoides para el extracto de acetona (TSA) fue de 71,54 mg equivalentes de ácido gálico/g de extracto y 8,80 mg equivalentes de quercetina/g de extracto, respectivamente, mientras que para el extracto de etanol (TSE) fue de 65,70 mg de equivalente de ácido gálico/g de extracto y 8,19 mg de equivalente de quercetina/g de extracto. El valor de la concentración inhibitoria media (CI50) de los extractos fue de 80,91 μg/mL para TSA y de 84,25 μg/mL para TSE. Los extractos tuvieron un factor de protección solar medio, para TSA fue de 12,92 y para TSE de 7,67. Conclusión: Los resultados evidenciaron que los extractos de Tabebuia serratifolia poseen gran variedad de compuestos químicos con actividad antioxidante y fotoprotectora.

Objetivo: Na presente investigação, foi determinado o rastreio fitoquímico, a atividade antioxidante e fotoprotectora in vitro dos extractos da casca de Tabebuia serratifolia. Métodos: Os extractos da casca foram obtidos por técnica de maceração utilizando acetona e etanol como solventes. Foram utilizados testes de coloração química padrão e/ou testes de precipitação para a análise fitoquímica preliminar. A atividade antioxidante foi avaliada pelo ensaio de 2,2'-difenil-1-picrilhidrazil (DPPH). O efeito fotoprotector foi estabelecido pelo método espetrofotométrico de Mansur. Resultados: A análise fitoquímica mostrou que os extractos possuem alcalóides, flavonóides, compostos fenólicos, quinonas, cumarinas, triterpenos e esteróides. O teor total de compostos fenólicos e flavonóides para o extrato de acetona (TSA) foi de 71.54 mg de equivalente de ácido gálico/g de extrato e 8.80 mg de equivalente de quercetina/g de extrato, respetivamente, enquanto que para o extrato de etanol (TSE) foi de 65.70 mg de equivalente de ácido gálico/g de extrato e 8.19 mg de equivalente de quercetina/g de extrato. O valor da concentração inibitória média (CI50) dos extractos foi de 80.91 μg/mL para o TSA e 84.25 μg/mL para o TSE. Os extractos apresentaram um fator de proteção solar médio de 12.92 para o TSA e de 7.67 para o TSE. Conclusão: Os resultados mostraram que os extractos de Tabebuia serratifolia possuem uma variedade de compostos químicos com atividade antioxidante e fotoprotectora.
