<abstract xmlns="http://www.w3.org/1999/xhtml">The apple (Malus domestica Borkh.) possesses a number of health-promoting properties. The main beneficial effects of apple fruits on human health are associated with the antioxidant properties of components synthesising in apple fruits during their growth and development. Phenolic compounds and flavonoids are such components that contribute significantly to the antioxidant capacity of fruits, thus enhancing their health properties. The purpose of this study is to compare the antioxidant properties (namely antioxidant capacity, ascorbic acid, total phenolic and flavonoid contents) of the ‘Idared’ and ‘Braeburn’ apple cultivars, grown under optimal growing conditions in the Goražde area. Ascorbic acid contents were estimated using the 2.6-dichlorophenolindophenol titration method, whereas total phenolics were determined using the Folin-Ciocalteu method. Furthermore, total flavonoids were determined using the aluminium chloride colorimetric assay, whereas the ferric reducing/antioxidant power assay was used to determine the total antioxidant capacity of the apple fruits examined. The average values of the ascorbic acid, the total phenolic and flavonoids contents, and the total antioxidant capacity of the ‘Idared’ apples under consideration were 8.09 mg 100 g−1, 34.56 mg gallic acid equivalents 100 g−1, 12.62 mg catechin equivalents 100 g−1 and 323.28 μmol Fe2+ 100 g−1of fresh weight, respectively. The average values of the total phenolic and flavonoids contents, as well as the antioxidant capacity of the ‘Braeburn’ apples examined were as follows: 8.89 mg 100 g−1, 33.4 mg gallic acid equivalents 100 g−1, 13.56 mg catechin equivalents 100 g−1 and 367.01 μmol Fe2+ 100 g−1 of fresh weight, respectively. The analyses performed indicate that the differences recorded in the parameter values between the apple cultivars ‘Idared’ and ‘Braeburn’ were statistically non-significant. A correlation data analysis confirmed that phenolic compounds are the carriers of the antioxidant activity of apples.</abstract>
