摘　　要：以两个品种(富士和国光)的苹果不同部位的多酚含量比较为目的,用3种不同溶剂(70%的甲醇、乙醇和丙酮)分别进行提取,对两个品种的果皮部位和果皮加肉部位进行多酚类物质的粗提取,通过福林酚法测定其含量。结果显示:3种不同溶剂的提取结果均表现为富士苹果的多酚含量显著高于国光苹果(P<0.05)。且两个品种均表现为果皮组的多酚含量高于果皮加果肉组。由此可见,富士苹果较国光苹果在多酚含量上占有优势,且多酚类物质在果实的果皮中含量较高。The purpose was to compare the polyphenol content from the different parts of the two cultivars（ Fuji and Ralls）. The two parts（ peel, fresh with peel） were respectively extracted by methanol, ethanol and acetone（ 70 %）. The polyphenol content was measured by Folin-Ciocalteu method. The results showed that the Fuji apple polyphenol content was significantly higher than Ralls（ P〈0.05）. The two cultivars showed polyphenol content of the skin was higher than the fresh with peel. Thus, the polyphenol content of Fuji has an advantage than the Ralls, and apple polyphenol is mainly distributed in the skin.
