    per liter (average content was 3057 mg gallic acid/L) and total anthocyanin contents ranged from 73.4 to 791.2 mg/L (average content was 403.4 mg/L). Determined values of antioxidant activity were within the interval 54.8-86.8% (average value was 74.5%) and the values of wine colour density varied between 0.944 and 4.592 (average value was 2.317). The statistical evaluation of the obtained results confirmed only weak linear correlation between total polyphenol content and total anthocyanin content, however strong linear correlations between total anthocyanin content and antioxidant activity, resp. wine colour density were observed. Our results also confirmed very highly significant linear relationship between wine colour density and total polyphenol content, resp. antioxidant activity and between antioxidant activity and total phenolic content.
