Several polyphenols have been tested in grape berries from Spain. The flavonoid content is important because of the pharmacological properties of these compounds, whereas resveratrol has been proved to be an antifungal, antiinflammatory and an anticarcinogenic compound. A reversed-phase HPLC method has been developed and applied to determine resveratrol, quercetine, quercitrine and rutine content in several grape berries samples in a single analysis. Covering the grapes with a preservative paper yields a healthier product, but one which has a lower polyphenol content than unprotected grapes.
几种多酚类物质已在西班牙的葡萄浆果中进行了测试。由于这些化合物的药理特性，类黄酮含量很重要，而白藜芦醇已被证明是一种抗真菌、抗炎和抗癌化合物。已开发出一种反相高效液相色谱法，并应用于在一次分析中测定多个葡萄浆果样品中的白藜芦醇、槲皮素、槲皮苷和芦丁含量。用防腐纸覆盖葡萄会得到更健康的产品，但该产品的多酚含量低于未受保护的葡萄。
