Anthocyanins in Cabernet Sauvignon grapes and wines were elucidated by HPLC-MS/MS. Major anthocyanins in Cabernet Sauvignon grape extract are malvidin 3-O-glucoside and malvidin 3-O-acetylglucoside. In matured wine, anthocyanins are transformed to anthocyanin-vinyl derivatives, ethyl bridged anthocyanin-flavanol adducts, and anthocyanin-flavanol adducts. The major anthocyanin pigments are malvidin 3-O-glucoside-pyruvate, malvidin 3-O-acetylglucoside-pyruvate, malvidin 3-O-coumaroylglucoside-pyruvate, malvidin 3-O-glucoside-4-vinylphenol, malvidin 3-O-acetylglucoside-4-vinylphenol, and malvidin 3-O-coumaroylglucoside-4-vinylphenol. The presence of syringetin 3-O-glucoside and syringetin 3-O-acetylglucoside has been established for the first time in grape and wine.
采用高效液相色谱-串联质谱法（HPLC-MS/MS）对赤霞珠葡萄及葡萄酒中的花色苷进行了鉴定。赤霞珠葡萄提取物中的主要花色苷为矢车菊素-3-O-葡萄糖苷和矢车菊素-3-O-乙酰葡萄糖苷。在成熟葡萄酒中，花色苷会转化为花色苷-乙烯基衍生物、乙基桥连花色苷-黄烷醇加合物以及花色苷-黄烷醇加合物。主要的花色苷色素为矢车菊素-3-O-葡萄糖苷-丙酮酸、矢车菊素-3-O-乙酰葡萄糖苷-丙酮酸、矢车菊素-3-O-香豆酰葡萄糖苷-丙酮酸、矢车菊素-3-O-葡萄糖苷-4-乙烯基苯酚、矢车菊素-3-O-乙酰葡萄糖苷-4-乙烯基苯酚以及矢车菊素-3-O-香豆酰葡萄糖苷-4-乙烯基苯酚。首次在葡萄和葡萄酒中鉴定出了丁香亭-3-O-葡萄糖苷和丁香亭-3-O-乙酰葡萄糖苷的存在。
