HPLC法测定葡萄与葡萄酒中的花色素苷

Determination of anthocyanin in Granoir grape and wine with HPLC

利用甲醇和超声波提取酿酒葡萄‘Granoir’中的花色素苷,利用高效液相色谱分别测定了该葡萄及酒中的花色素苷。在测得的9种花色素苷中,均以二甲花翠素3-O-葡萄糖苷含量最高,分别占总成分的39.71%和69.55%,其次为二甲花翠素3-O-(6-O-对香豆酰)葡萄糖苷,构成了Granoir葡萄及葡萄酒中的主要呈色成分。

Anthocyanin in ＇Granoir＇ grape was extracted with methanol and ultrasonic, and the an- thocyanin in ＇ Granoir＇ grape and ＇ Granoir＇ wine was detected with HPLC. Among the 9 anthocya- nins, the content of malvidin 3 - O - glucoside was the highest in ＇ Granoir＇ grape and wine, and the respective contents were 39.71% and 69.55 % maryl） glucoside. These anthocyanins in ＇Granoir＇ , secondly was malvidin 3 - O - （6 -O - p - cou- grape and wine were main pigments
