QUINO, Marco L  and  ALVARADO, Juan A. Antioxidant capacity, total content in phenols of bee honey harvested in different regions of Bolivia. Rev. Bol. Quim [online]. 2017, vol.34, n.3, pp.65-71. ISSN 0250-5460.

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.
