Abstract
Se analizó el Contenido Total de Fenólicos (TPC), y la Capacidad Antioxidante Total (TAC) de cuarenta y cinco muestras de miel de abejas de diferentes regiones de Bolivia, correspondientes a los siguientes eco-sistemas: Bosque Seco Interandino, Bosque Boliviano-Tucumán, Chaco, Pre-Puna, Yungas y Bosque Amazónico subandino. Se emplearon los ensayos ABTS y FRAP para establecer la TAC. El TPC, contenido total de fenólicos se obtuvo aplicando el ensayo de Folin Ciocalteu. La mayor actividad antioxidante total del FRAP fue de 247,54 - 690,68 μmol ET / 100g, correspondiente a la región de Chaco. La región de los bosques secos interandinos presentó el TAC más alto (32,49 - 57,44 μmol ET / 100 g) según el método ABTS. La región con mayor contenido de Fenólicos Totales es la región de Chaco (115.04 - 190.56 mg EAG / 100g). También se estableció una correlación importante entre el método FRAP y el contenido total de fenólicos (r = 0,69), lo que indica la influencia de estos compuestos sobre la actividad antioxidante de la miel.
Forty-five samples of Bolivian bee honey proceeding from the following eco-regions: Inter-Andean Dry Forest, Bolivian-Tucuman Forest, Chaco, Pre-Puna, Yungas, and sub-Andean Amazon Forest, were analyzed with respect to antioxidant properties and the Total Phenol Contents. The ABTS and FRAP methods were employed to establish the antioxidant indexes. The total phenolics content was achieved by applying the Folin Ciocalteu method. The FRAP highest total antioxidant activity was 247.54 - 690.68 μmol ET / 100g, corresponding to the Chaco region. The region of the inter-Andean dry forests showed the highest TAC (32.49 - 57.44 μmol ET / 100 g) by the ABTS method. The region with the highest total ash content was the Chaco region (115.04 - 190.56 mg EAG / 100g). An important correlation was also established between the FRAP method and the Total Phenol Content (r = 0.69), which indicates the influence of these compounds on the antioxidant activity of honey.
