dc.description.abstractEste artículo presenta la determinación de la capacidad antioxidante y contenido de polifenoles totales en dos extractos, acuoso y orgánico, de tallos de Stevia Rebaudiana variedad Morita II. La capacidad antioxidante se determinó a través de varios ensayos in vitro: el método 1,1-difenil-2-picril-hidrazilo (DPPH), el ensayo de decoloración ácido 2,2′-azino-bis-3-etilbenzotiazolin-6-sulfónico (ABTS), el ensayo de la Capacidad de reducción Férrica Antioxidante (FRAP) y polifenoles totales por el reactivo Folin-Ciocalteu. Los resultados se analizaron mediante correlación Person´s.  Este trabajo se realizó con el fin de darle un valor agregado al tallo de Stevia y potencializar su uso como fuente de compuestos antioxidantes. Los resultados indican que los extractos de los tallos de Stevia cultivados en Colombia poseen una mayor actividad inhibidora de radicales libres comparado con los reportes de la literatura en cuanto a hoja y tallo. Por lo tanto se puede concluir que los tallos son una fuente accesible de antioxidantes.spa
dc.description.abstractThis paper presents the determination of antioxidant capacity and total polyphenol content in both aqueous and organic extracts of Stevia Rebaudiana stems variety Morita II. The antioxidant capacity was determined through various in vitro assays: Method 2 1,1-diphenyl-picryl-hidrazyl (DPPH) assay, discoloration 2,2'-azino-bis-3-ethylbenzthiazoline-6- sulfonic acid (ABTS) assay, ferric ion reducing antioxidant power (FRAP), and total polyphenols by Folin-Ciocalteu. The results were analyzed by Person's correlation. This work was done in order to give added value to the stem of Stevia and their potential use as a source of antioxidant compounds. The results indicate that extracts of Stevia stems grown in Colombia have greater inhibitory activity of free radicals compared to reports in the literature regarding leaf and stem. Therefore it can be concluded that the stems are an accessible source of antioxidants.eng
