【摘要】 以福建闽东山区主栽的7种树莓果实为材料，测定了其可溶性蛋白、总糖、还原糖、维生素E、类黄酮、花色苷、鞣花酸、水杨酸含量及SOD酶活性，并运用主成分分析法对树莓果实的功能成分进行了综合评价。结果表明：不同品种树莓果实的功能营养成分存在显著差异，其中，黑钻秋炫的游离水杨酸、还原糖及总糖含量最高，黑钻秋韵的SOD酶活性最高，自由的花色苷和鞣花酸含量最高。在主成分分析中，选取了前3个主成分，累计方差贡献率达到87.807%，综合得分排名从高到低依次为黑钻秋炫、仙女、柳林、黑钻秋韵、妮丝、自由、掌叶覆盆子，这对福建闽东山区不同类型产品加工利用所需树莓品种的选育具有一定的参考价值。更多还原

【Abstract】 Seven kinds of raspberry fruits in east Fujian mountainous area were used as materials. The contents of soluble protein, total sugar, reducing sugar, vitamin E, flavonoids, anthocyanins, ellagic acid, salicylic acid and superoxide dismutase(SOD) activity were measured, and the functional components of raspberry fruits were comprehensively evaluated by principal component analysis. The results showed that there were significant differences in the functional nutritional components among different varieties of raspberries, among which the contents of free salicylic acid, reducing sugar and total sugar in Heizuanqiuxuan were the highest, the SOD activity in Heizuanqiuyun was the highest, and the contents of anthocyanins and ellagic acid in Ziyou were the highest. In the principal component analysis, the first three principal components were selected,and the cumulative variance contribution rate reached 87.807%. The comprehensive ranking compliance of seven raspberry fruits from high to low was Heizuanqiuxuan, Xiannv, Liulin, Heizuanqiuyun, Nisi, Ziyou and Rubus chingii Hu. This study has a certain reference value for the variety selection of raspberry fruits for processing and utilizing different types of products in the mountainous areas of eastern Fujian.更多还原
