The phenolic composition and the antioxidant capacity of Serbian red wines

Abstract

The aim of this study was to determine the phenolic composition and free radi- cal scavenging activityof some Serbian commercially red wines by using DPPH assays. The wines of red grape varieties and different vintage were analysed in June 2012. Standard spectrophotometric methods of the analysis for general wine components were used for the preliminary control of the selected wines. Anthocyanins in the wine were measured by the HPLC method. Among the red wines tested, “Medvedja krv” and “Vranac” contained the highest total phenolic content with 3080±101 and 2850±93 mg/l, respectively. All analyzed red wines exerted remarkable antioxidant activities. In all cases,malvidin-3-glucoside was a predominant anthocyanin.According to the obtained results, the red wines from Serbia could be a good dietary source of polyphenols.
