Abstract

ESPINOSA MANRIQUE, Wilfred E; GARZON SALCEDO, Luis C. A  and  MEDINA VARGAS, Oscar J. Validation of an analytical method for quantification of total polyphenols in microwave-assisted extraction processes for the Colombian species Vaccinium meridionale. Rev. colomb. cienc. quim. farm. [online]. 2016, vol.45, n.1, pp.109-126. ISSN 0034-7418.  https://doi.org/10.15446/rcciquifa.v45n1.58023.

In this work, we show the development and validation of an analytical method for quantification of total polyphenols with Folin-Ciocalteu reagent (F-C) in microwave-assisted extraction processes for Colombian species Vaccinium meridionale. Experimental results of selectivity, linearity, repeatability and accuracy evidence that the methodology proposed is reliable to evaluate the effect of the extraction conditions over the quantity of polyphenols removed.
