中文摘要:

      目的 探究赤霞珠葡萄酒酚类物质的产区差异性。方法 利用高效液相色谱法分析新疆天山北麓产区、焉耆盆地产区与山东半岛产区赤霞珠葡萄酒中酚类物质组成与含量, 结合多元统计方法进行评价。结果 新疆天山北麓产区、焉耆盆地产区与山东半岛产区赤霞珠葡萄酒的酚类物质含量差异较大, 其中新疆两产区的原花青素B1、儿茶素、表儿茶素、对香豆酸、总黄烷醇类、总黄酮醇类、总类黄酮及总酚含量显著高于山东半岛产区(P<0.05), 焉耆盆地产区芦丁、槲皮苷、白藜芦醇含量显著高于山东半岛产区(P<0.05)。基于酚类物质的聚类分析结果显示, 当欧氏距离超过15时, 山东半岛产区样品聚为一类, 新疆两个产区葡萄酒样品聚在一起; 基于酚类物质的Fisher判别分析能区分山东半岛产区样品, 对新疆两个产区个别样品有误判, 回代检验与交叉验证合计正确率分别为91.30%和86.96%。结论 新疆天山北麓、焉耆盆地与山东半岛产区赤霞珠葡萄酒酚类物质具有明显的产地差异性。

英文摘要:

      Objective To explore the differences of phenolic compounds in Cabernet Sauvignon wines producing areas. Methods The composition and content of phenols in Cabernet Sauvignon wines from the Northern Foot of Tianshan Mountain, Yanqi Basin and Shandong Peninsula were analyzed by high performance liquid chromatography, and evaluated combined with multivariate statistical methods. Results The content of phenolic compounds in Cabernet Sauvignon wine from the Northern Foot of Tianshan Mountain, Yanqi Basin and Shandong Peninsula were different. The content of proanthocyanidin B1, catechin, epicatechin, para-coumaric acid, total flavanols, total flavone alcohols, total flavonoids and total phenols in Cabernet Sauvignon wines from 2 producing areas of Xinjiang were significantly higher than those from Shandong Peninsula producing area (P<0.05), while the content of rutin, quercetin and resveratrol in wines from Yanqi Basin were significantly higher than those from Shandong Peninsula (P<0.05). The results of cluster analysis based on phenolics showed that the samples from Shandong Peninsula were grouped into one group, and the samples from 2 producing areas of Xinjiang were grouped together when the Euclidean distance exceeded 15. The samples from Shandong Peninsula producing area could be identified by Fisher discriminant analysis based on phenolic compounds, but the individual samples from 2 producing areas in Xinjiang were misjudged. The accuracy of return test and cross verification of discriminant analysis were 91.30% and 86.96%, respectively. Conclusion There are obvious original differences in phenolic compounds of Cabernet Sauvignon wines between the northern foot of Tianshan Mountain, Yanqi Basin and Shandong Peninsula.
