Resveratrol is a polyphenolic compound belongs to the stilbene family which has two phenolic rings. It is a natural compound found in red grapes, peanuts, pistachios, fruits such as blackberries or raspberries, plants like Yucca, fescues, hellebore, trees such as eucalyptus and fir and in chocolate. The biologically active form of resveratrol is its trans isomer [1]. Two forms of trans resveratrol are found in natural sources, free trans-resveratrol and a glycoside form of it, polydatin (Fig. 1) Determination of trans-resveratrol forms in red grape drinks of the market can be applied as a method for fraud detection in grape juice drinks. So, in this study a coacervative extraction method [2] was optimized for extraction of free trans resveratrol and polydatin from grape juice drinks followed by its determination by gradient HPLC. Response surface methodology was applied for the optimization process.
