Resveratrol, existing in two isomeric trans- and cis-forms, is a phytoalexin that has pharmacological activities, like anticancer and anti-cardiovascular diseases as well as life-span increasing properties. Grapes are good sources for resveratrol introduction in the human diet not only directly, but also through its products: wine. In the present work, traps-resveratrol determination and the separation of resveratrol isomers were investigated by the use of micro-high performance liquid chromatography. The analysis conditions were optimized. The baseline separation of trans- and cis-resveratrol was obtained. Further, a traps-resveratrol determination of some grapes growing in Shacheng, Huailai, Hebei province, China was carried out with our analytical method. The concentrations were 6.77 +/- 0.12 and 3.95 +/- 0.18 (mu g/g fresh weight) for merlot and cabernet sauvignon grapes, respectively.
