15 wines from Sicily (Italy), obtained in the provinces of Palermo, Trapani, Agrigento, Catania, coming from winemaking of Vitis vinifera L. cvs Nero d'Avola, Merlot, Cabernet Sauvignon, Cabernet franc, Sangiovese, Syrah, Alicante Bouschet, during vintages 2000, 2001, 2002, have been analysed for the main stilbenic compounds. The occurrence of piceatannol (trans-3,3',4,5'-tetrahydroxy-stilbene) has been recorded for the first time in the wine (average value 0.18 mg/l, ranging from not detectable to 0.45 mg/l). The compound is claimed to have powerful biological activities, by preventing some diseases, since it is an inhibitor of protein-tyrosine chinase and 5 alpha-reductase, an antileukaemic, antioxidant and radical scavenger agent. Trans-resveratrol ranged from 0.14 mg/l to 1.45 mg/l (average value 0.71 mg/l), while cis-resveratrol ranged from 0.06 mg/l to 16 mg/l (average value 0.28 mg/l). Under quality-oriented cultural practices in the vineyard and under a mild enological technology, a higher level of stilbenic compounds occurred
