The utility of high-performance liquid chromatography-mass spectrometry using electrospray (ESI) and sonic spray (SSI) ionization for the characterization of nonvolatile phenolic compounds is tested using the special Hungarian wine Tokaj aszu of 1983 vintage. Besides caffeic-, ferrulic-, chlorogenic-, and 3,4-dimethoxycinnamic acids; 3,4-dimethoxycinnamoyl-, ferruloyl-, and galloyl-glucose; gentisic acid-beta-D-glucoside; theogallin; and resveratrol-3-O-beta-D-glucoside, 26 flavonoids can be identified. It is shown that because of its higher sensitivity, SSI is a more powerful tool for characterization and monitoring of nonvolatile phenolic compounds than ESI.
采用1983年份的匈牙利特色葡萄酒托卡伊阿苏,测试了使用电喷雾(ESI)和超声喷雾(SSI)电离的高效液相色谱 - 质谱联用技术对非挥发性酚类化合物进行表征的效用。除了咖啡酸、阿魏酸、绿原酸和3,4 - 二甲氧基肉桂酸;3,4 - 二甲氧基肉桂酰基、阿魏酰基和没食子酰基葡萄糖;龙胆酸 - β - D - 葡萄糖苷;表儿茶素没食子酸酯;以及白藜芦醇 - 3 - O - β - D - 葡萄糖苷外,还可鉴定出26种黄酮类化合物。结果表明,由于具有更高的灵敏度,与电喷雾电离相比,超声喷雾电离是表征和监测非挥发性酚类化合物更强大的工具。
