建立了黄酒中葡萄糖、果糖、异麦芽糖、异麦芽三糖、麦芽糖、潘糖、麦芽三糖共7种糖类的高效阴离子交换色谱分离-积分脉冲安培检测的方法。以氢氧化钠和醋酸钠为淋洗液进行梯度洗脱，CarboPacTM 10阴离子交换柱进行分离。该方法可在26 min内实现黄酒中7种糖类的定量分析，在0.5~50 mg／L浓度范围内线性关系良好，样品定量限为0.1 g／L，加标回收率为76.5％~108.4％，精密度（ RSD）为3.02％~8.23％。将该法用于不同厂家不同批次的绍兴加饭酒中各种糖类含量的检测，基于所得的检测结果，利用中位数法构建了标准指纹图谱，并采用夹角余弦法评价了各个样品与标准指纹图谱之间的相似度。结果初步显示，不同厂家加饭酒之间的相似度差别较大，该法可作为区别不同厂家酒的依据之一。

An analytical method for the determination of glucose,fructose,isomaltose,isomal-totriose,maltose,panose and maltotriose was developed by high performance anion exchange chromatography coupled with integrated pulsed amperometric detection. The analysis was per-formed on a CarboPacTM10 column with gradient elution of NaOH-NaOAc as mobile phases. The seven sugars were well separated in less than 26 min and showed good linear correlation coeffi-cients between 0. 5 and 50 mg/L. The detection limits( LODs)were 0. 1 g/L. The recoveries ranged from 76. 5% to 108. 4% at different spiked levels. The relative standard deviations were between 3. 02% and 8. 23%. The established method was applied in determining the seven sugars in different batches of Shaoxing Jiafan rice wines from different manufacturers. The standard fingerprints were established by median values using the obtained results. Similarities of the fin-gerprints of the samples to the standard were calculated by using angle cosine. The results showed that the similarities of wines from different manufacturers were significantly different, so the method could be used for the identification of rice wines from different manufacturers.
