不同年份及产区红葡萄酒花色苷组成分析

Composition of anthocyanins of red wines from different years and regions

【目的】分析花色苷与葡萄酒年份及产区的关系,为葡萄酒感官品鉴提供依据。【方法】以二甲花翠素-3-O-葡萄糖苷为标准样品,利用高效液相色谱分析法,对来自不同产区的45款不同年份酿制的红葡萄酒的花色苷组成及其质量浓度进行测定分析。【结果】在45种不同年份酿制且来自不同产区的红葡萄酒中,共测定出花翠素-3-O-葡萄糖苷、花青素-3-O-葡萄糖苷、3′-甲花翠素-3-O-葡萄糖苷、甲基花青素-3-O-葡萄糖苷、二甲花翠素-3-O-葡萄糖苷、甲基花青素-3-O-(6-O-乙酰)葡萄糖苷、二甲花翠素-3-O-(6-O-乙酰)葡萄糖苷、甲基花青素-3-O-(6-O-对香豆酰)葡萄糖苷、二甲花翠素-3-O-(6-O-对香豆酰)葡萄糖苷等9种花色苷,其中二甲花翠素-3-O-葡萄糖苷和二甲花翠素-3-O-(6-O-乙酰)葡萄糖苷为主要单体花色苷,分别占总花色苷的50%和15%,是葡萄酒的主要2种呈色物质。葡萄酒花色苷与其年份和产区有一定的相关性。【结论】不同酒样单体花色苷组成及质量浓度存在显著差异,其与酒样的生产年份、葡萄品种、产区均有一定相关性。

【Objective】The relationship between anthocyanins with years and regions was investigated to provide basis for sensory taste.【Method】This experiment analyzed the composition and content of anthocyanins of 45 red wines from different regions and years by HPLC,with dimethyl delphinidin-3-O-glycosidase as standard sample.【Result】Nine anthocyanins including delphinidin 3-O-glucoside,anthocyanins-3-O-glucoside,3′-a delphinidin 3-O-glucoside,methyl anthocyanins-3-O-glucoside,dimethyl delphinidin 3-Oglucoside,methyl anthocyanins-3-O-（6-O-acetyl）glucoside,dimethyl delphinidin 3-O-（6-O-acetyl）glucoside,methyl anthocyanins-3-O-（6-O-of coumaric acid）glucoside,and dimethyl delphinidin 3-O-（6-O-of coumaric acid）glucoside were detected in 45 wines.Dimethy delphinidin 3-O-glucoside and dimethyl delphinidi3-O-（6-O-acetyl）glucoside were the main species with ratios of 50% and 15%,respectively.The composition and content of anthocyanins of different wines were effected partly by years and regions.【Conclusion】There were significant differences in composition and content of anthocyanins of different wines,which were are effected by years,grape varieties and regions.
