UNICIENCIA55912019-04-23T03:34:19Z Comparison of total phenolic compounds and antioxidant activity of four brands of infusions of Hibiscus sabdariffa (Malvaceae) marketed in Costa Rica Análisis comparativo de compuestos fenólicos totales y actividad antioxidante de cuatro marcas de tisanas de Hibiscus sabdariffa (Malvaceae) comercializadas en Costa Rica Agüero, Melissa Segura, Cindy Parra, Jonathan Hibiscus sabdariffa Roselle tisanes anthocyanins phenolic compounds antioxidant. Hibiscus sabdariffa rosa de Jamaica tisanas antocianinas compuestos fenólicos antioxidante. Consumption of Roselle (Hibiscus sabdariffa) infusion is widespread in Costa Rica due to its known cardioprotective effects associated with the presence of phenolic compounds, mainly consisting of anthocyanins. This paper established the differences in the phenolic compounds profile and their corresponding antiradical activity amongst different distributors of Hibiscus sabdariffa infusion in Costa Rica. Tannins, flavonoids and anthocyanins were identified qualitatively. The total quantity of phenolic compounds was calculated using the Folin-Ciocalteu methodology and the antioxidant activity was quantified using the DPPH method. Results show all samples contained phenolic compounds, including anthocyanins. However, there are significant differences in the content of phenolic compounds and their corresponding antiradical activity amongst the different manufacturers of infusions. Therefore, we can conclude that the phenolic compound profile of infusions in this study varies according to each manufacturer. Las tisanas de rosa de Jamaica (Hibiscus sabdariffa) son consumidas en Costa Rica por su conocido efecto cardioprotector asociado a la presencia de compuestos fenólicos, principalmente antocianinas. Este trabajo estableció diferencias en el perfil de compuestos fenólicos y su actividad anti-radical entre diferentes comercializadores de tisanas de Hibiscus sabdariffa en Costa Rica. Se identificaron cualitativamente taninos, flavonoides y antocianinas. Se cuantificó la cantidad total de compuestos fenólicos por el método de Folin-Ciocalteu y se cuantificó la actividad antioxidante con el método de DPPH. Todas las marcas comerciales demostraron presencia de compuestos fenólicos, incluyendo antocianinas; sin embargo, se encontraron diferencias significativas en el contenido de compuestos fenólicos y actividad anti-radical, entre los diferentes productores de tisanas. Por ello, se concluye que en el mercado costarricense, el perfil en compuestos fenólicos de las tisanas en estudio varía de acuerdo con el productor.
