摘要: 本研究建立了用HPLC同时测定葡萄酒中没食子酸、(+)-儿茶素等10种单体酚的方法。色谱条件为:Hibar RT Lichrospher反相C18柱,流动相A为水:乙酸(98:2),流动相B为乙腈,梯度洗脱,流速为1.0ml/min,检测波长为280nm。在该色谱条件下各个单体酚在30min内得到了良好的分离,各物质的含量与峰面积呈良好的线性关系,且回收率较高,重复性好,且具有定量准确、快速等特点。结果表明,三种葡萄酒均被检测到了这10种单体酚,且它们在红葡萄酒中的含量显著高于白葡萄酒。

Abstract: A new method for simultaneous determination of 10 mono- phenols in wines with HPLC was studied. Chromatographic separation was performed by Hibar RT Lichrospher RP- C18 precolumn. A gradient elution consisting of solvent A (water: acetic acid, 98:2, V/V) and solvent B (acetonitrile) was applied with flow rate at 1.0 ml/min and detection wavelength at 280 nm。Under the chromatographic conditions, the calibrations, curves are linear with r >0.999 and recoveries of several mono- phenols >80 %. The results showed that 10 mono- phenols are found in three wines and the contents of several mono- phenols in red wines are higher than those in white wines.
