摘要: 建立了同时测定葡萄酒中没食子酸、原儿茶酸、丁香酸、p-香豆酸、咖啡酸、绿原酸和阿魏酸等7种生物活性酚酸的反相高效液相色谱电化学分析新方法,并测定了5种国产不同品牌的葡萄酒.采用HypersilODS色谱柱(250mm×4.0mm,5.0μm),流动相为甲醇-4%醋酸,梯度洗脱,流速为0.8mL/min,工作电压为0.7V,柱温为30℃.实验结果表明,电化学法的检出限比紫外法的检出限低4~600倍.

Abstract: A rapid, sensitive and accurate reverse phase HPLC-ECD method for simultaneous determination of seven kinds of bioactive phenolic acids(gallic acid, protocatechuic acid, syringic acid, p-coumaric acid, caffeic acid, chlorogenic acid, ferulic acid) in five different types of wine was developed. The separation was performed on Hypersil ODS column(250 mm×4.0 mm, 5.0 μm) by gradient elution. The mobile phase consisted of CH-3OH-4%HAc. The flow rate was 0.8 mL/min. The working potential was 0.7 V and column temperature was 30 ℃. The experimental results showed that the seven kinds of phenolic acids were separated satisfactorily. The detection limit of phenolic acids with ECD was 4-600 times greater than those obtained with UV detection.

Key words: HPLC, Electrochemical detection, Wine, Phenolic acid
