Trans -Resveratrol Concentration in Wines Produced in Greece

A direct injection-HPLC method, based on existing methods, slightly modified, was used to analyse commercially available wines in the Greek market for their trans -resveratrol content. Red wines produced from French, or French and Greek cultivars were found to have relatively higher amounts of trans -resveratrol compared with those produced exclusively from native Vitis vinifera cultivars. However, the wines produced from the original Greek Vitis vinifera cultivars, Kotsifali and Mantilaria, appeared to contain important amounts of trans -resveratrol. White wines were found to have markedly lower concentrations of this stilbene in comparison with red wines.
