A RAPID METHOD OF DETERMINATION OF TRANS-RESVERATROL IN ROMANIAN COMMERCIAL WINES BY REVERSED-PHASE HPLC

Resveratrol (trans-3,5,4’-trihydroxystilbene) is a phytoalexin produced naturally by 72 different plant species especially grapevines, Japanese knotweed and pines in response to some exogenous factors such as UV radioation, chemical stress and fungal parasites. With the discovery of the „French para...
