Background : Resveratrol is the stillbenoid material made by the stress factors from the plants like grape, blueberry and Polygonum cuspidatum and it has useful pharmacological activity such as anti-cancer and longevity effect. Although grapevine contains less resveratrol compared to Polygonum cuspidatum, it is expected that a large amount of resveratrol can be obtained using by-products from the processing because grapes are one of the crops grown and processed considerably in south Korea. Methods and Results : As the result of the analysis of resveratrol content in grape extract using high-performance liquid chromatography (HPLC), it was showed that the amount of the resveratrol was 46.8~47.8 mg(about 4.7~4.8%) per 1 g of grape extract. The method used for purifying resveratrol from grape extract was a column chromatography and adsorption resin was used in packing the column. The content of resveratrol in the eluate obtained by column chromatography was analyzed by HPLC. Then the solid content obtained by freeze-drying was analyzed to get the purity and the collect rate of the resveratrol by measuring the weight. The result showed that the purity of the resveratrol in eluate obtained by column chromatography was measured to 15.2~18.1% and collect rate was up to 95%. Conclusion : From the above results, we have isolated resveratrol which is more pure than the conventional from grape extract and assumed that it is helpful to produce functional material at a low cost by using this isolation method.
