Influence of Seasonal Variation on Antioxidant and Total Phenol Activity of Red Propolis Extracts

Recently there has been a growing interest in the discovery of antioxidant substances for use in food and medicinal products, as substitutes for synthetic antioxidant substances. Propolis has been the object of pharmacological studies due to its biological activity amongst antioxidant properties. In this work, the seasonal influence on antioxidant activity and total phenol content of red propolis ethanolic extracts was evaluated, as well as the established correlation between them, the antioxidant capacity being evaluated by different methods (DPPH, H2O2 and total antioxidant activity). The results have demonstrated that the red propolis analyzed possesses antioxidant activity, as demonstrated by the methods used.
