建立了高效液相色谱测定白酒中安赛蜜、糖精钠的方法。采用在沸水浴条件下,将白酒样品50.0 g用旋转蒸发仪减压蒸发至近干后用水定容至10 mL,进液相色谱分析;用AQ-C18色谱柱（250×4.6 mm）,以0.02 mol/L的乙酸铵-甲醇（90∶10）为流动相,二极管阵列检测器在波长220 nm进行检测。结果表明,该方法的检出限低至安赛蜜0.014 mg/kg,糖精钠0.019 mg/kg,被测样品加标回收率：安赛蜜为97.5%,糖精钠102.0%。

A HPLC method for simultaneous separation and determination of acesulfame-K and saccharin sodium in liquor had been developed.Under boiling water bath conditions,vacuum evaporation of 50.0 g liquor samples was carried out to almost dry by rotary evaporation instrument and then constant volume to 10 mL by use of water for HPLC analysis,an AQ-C18 column（250×4.6 mm） was used with 0.02 mol/L NH4Ac-methanol（90∶10） as eluent,then detected at 230 nm through a photo-diode array detector.The detection limits of acesulfame-K and saccharin sodium were 0.014 mg/kg and 0.019mg/kg respectively,and their recovery rate were 97.5 and 102.0 % respectively.
