摘要:

建立一种新型、快速测定葡萄酒中多种单体酚的超高效液色谱方法。采用Waters BEH C18色谱柱(2.1 mm×50 mm,1.7 μm);色谱条件:流动相A为1%乙酸溶液,流动相B为乙腈;流速为0.2 mL/min;检测波长为210~400 nm;梯度洗脱15 min。方法精密度(n=6)实验的17 种酚类物质的平均相对标准偏差为0.25%~0.66%,对葡萄酒进行加标回收率实验的17 种酚类物质回收率范围为85.10%~102.33%。该方法简单省时、精确可靠、重复性好,非常适用于葡萄酒中酚类物质的定性与定量分析。

Abstract:

The aim of study was to develop a novel method using ultra-performance liquid chromatography (UPLC) to rapidly
determine monophenols in wine. The UPLC system equipped with C18 BEH analytical column (2.1 mm × 50 mm, 1.7 μm)
was kept at 30 ℃ by column oven, utilizing A 1% acetic acid and B acetonitrile mobile phase in the gradient elution mode
within 15 min. The flow rate was 0.2 mL/min. A diode array detector (DAD) was used to monitor signals at 210?400 nm.
The method precision (n = 6) for 17 compounds expressed as RSD was 0.25%?0.66% and average recovery rates of spiked
wine samples were 85.10%?102.33%. The new method was simple, time-saving, accurate, reliable and prefect reproducible.
Therefore, it is a promising method for the identification and quantitation of phenolic compounds in wine.
