HPLC Analysis of Resveratrol and Piceid during the Development of Grape Berries

Resveratrol(Res) and piceid(PD) in grape berries were determined by using high performance liquid chromatography(HPLC),combining with the C₁₈ solid extraction.The result showed that the contents of Res in Carbernet Gernischet and Rkatsiteli existed obvious difference during the development of grapes berries.The contents of Res and PD were high in Carbernet Gernischet grapes berries,while the content of Res was low and the content PD kept decreasing during the development of Rkatsiteli grapes berries.
