In this paper, using high performance liquid chromatography (HPLC), trans resveratrol and trans piceid contents in different style wines (red,white,fresh,aged) from three typical grape regions in China(Hebei Huailai, Ningxia Qingtongxia,Xinjiang Changji) were determined. The role of grape varieties, grape regions and aging practice played in resveratrol contents in wines were discussed. The results showed that total resveratrol content in merlot red wine from Ningxia Qingtongxia was the highest(6.79mg/L). The resveratrol contents in merlot wines were higher than those in Cabernet Sauvignon.The resveratrol contents in all the red wine was much higher than in white wines. There was no significant difference in total resveratrol concentrations between fresh wines and aged wines, while trans-piceid contents increased and trans-resveratrol contents decreased during aging process.
