Abstract

LILLO, A et al. Cuantificación espectrofotométrica de compuestos fenólicos y actividad antioxidante en distintos berries nativos del Cono Sur de América. RIA. Rev. investig. agropecu. [online]. 2016, vol.42, n.2, pp.168-174. ISSN 1669-2314.

The objective of this work was to identify different types of phenols in ethanol extracts of some berries native to the Southern Cone of South America and blueberry by spectrophotometric methods and their relationship to antioxidant activity. For this analysis of Total Phenols, Total Flavones and Flavonols, Total Proanthocyanidins, Total Anthocyanins, Total Phenolic Acids, Total Tannins and antioxidant activity by the method of DPPH+ and ABTS•+, in extracts of Ugni molinae, Aristotelia chilensis, Berberis darwinii, Luma apiculata and Vaccinium corymbosum. The berry that had the highest concentration of Total Phenols, Total Anthocyanins and Total Proanthocyanidins was A. chilensis, being also, the highest antioxidant power. While V. corymbosum was the lowest concentration of Total Phenols, Total Flavones and Flavonols, and Total Tannins, with antioxidant activity well below berries native to the Southern Cone. The berries have analyzed variations in the content of different phenols studied.

Keywords : Flavonoids; Antioxidant activity; Tannins.
