Characterization of Wines by Trans-Resveratrol Concentration: A Case Study of Romanian Varieties
The goal of this study was to determine the trans-resveratrol concentration in wine. A set of
70 wine samples from Romania, produced according to the appellation of origin system,
were analyzed by reverse-phase high performance liquid chromatography. White wines
were found to have markedly lower concentrations of trans-resveratrol in comparison with
red wines. The values were between 0.025 to 10.23 mg/L for red wine and from 0.074 to
2.572 mg/L for white wine. Red wine is a good dietary source of resveratrol.
