VIT, Patricia et al. Czech honey categorized according to their antioxidant activity. Acta bioquím. clín. latinoam. [online]. 2008, vol.42, n.2, pp.237-244. ISSN 0325-2957.

The bioactivity of honey has been used in traditional and modern apitherapy. The botanical origin of honey causes variations in this product's active principles and color, from almost colorless whitish to dark brown in the amber scale. The total antioxidant activity (TAA) of 50 honeys sent to the service of Chemical Analysis of the Institute of Apicultural Investigations in Dol, Czech Republic, was evaluated by the method of the radical cation ABTS·+. The following variations of AAT (µmols Trolox equivalent) were found for 22 floral honeys (60.12-287.55), 15 honeydew honeys (53.71-280.04) and 13 mixed honeys (43.55-290.35). The TAA did not vary significantly according to the botanical origin but was directly proportional to color and content of flavonoids and polyphenols. A classification of honey according to its low, medium and high TAA is suggested.
