摘　　要：为制备血脂干预型复合苹果汁,以具有降血脂功效的多酚单体为依据,通过主成分分析法及聚类分析法评价20个苹果品种的10种多酚单体及果汁的理化特性,筛选出多酚单体含量高及果汁品质评价好的2个苹果品种。结果表明:1)20个苹果品种中多酚单体的含量存在较大差异,其中阿克苏和秦冠含有的绿原酸含量居前2位,儿茶素、表儿茶素和根皮苷含量也居前列;2)以具有血脂干预功效的多酚单体成分绿原酸、表儿茶素、儿茶素和根皮苷为主要成分,对10种多酚单体进行主成分及聚类分析,结合果汁品质评价,确定阿克苏和秦冠是血脂干预型且果汁品质较好的2个苹果品种。In order to prepare the blood lipid interfering compound apple juice,10 kinds of polyphenols and basic physicochemical indexes of 20 apple samples were analyzed and evaluated by principal component analysis(PCA)and cluster analysis(CA).Then,based on the polyphenolic monomer with hypolipidemic effect,two kinds of apple varieties with high blood-fat reducing efficacy and high fruit juice quality were selected.The results showed that the contents of polyphenolic monomers in 20 apple varieties were quite different.The contents of chlorogenic acid of Aksu and Qinguanwas were the top two,and the contents of catechin,epicatechin,and phlorizinwere also among the top.Additionally,10 polyphenolic monomers were analyzed by principal component and cluster analysis with chlorogenic acid,epicatechin,catechins and chloroalin as the main component of polyphenol monomers with the effect of blood lipid intervention.Combined with fruit juice quality evaluation,Akesu and Qinguan were identified as 2 apple varieties with high blood lipid intervention and good juice quality.
