摘　　要：目的建立同时、快速测定饮料中葵子麝香、佳乐麝香、二甲苯麝香和麝香酮4种人造麝香的气相色谱质谱联用分析方法。方法以芒果汁、乌龙茶、咖啡、草莓奶等不同基质的饮料为原料,样品选用正己烷进行提取,采用气相色谱-质谱联用(GC/MS)外标法进行定性定量分析。结果葵子麝香、佳乐麝香、二甲苯麝香和麝香酮4种人造麝香在0.1~1.0μg/m L浓度范围内线性良好,相关系数为0.9999~1.0000。空白样品添加水平分别为20、200、400μg/kg时,回收率在81.3%~97.5%之间,相对标准偏差在2.5%~7.5%之间,以上4种人造麝香的方法检出下限均可达5.0μg/kg。结论本方法简单、快速、准确,可满足饮料中4种人造麝香的同时检测及确证需求。Objective A rapid analytical method was developed for the determination of 4 kinds of artificial musk (musk ambrette, galaxolide abbalide, musk xylene, and ketone musk) in beverages by gas chromatography-mass spectrometry (GC/MS). Methods Totally 4 artificial musk residues were extracted from the samples(mango juice, tea, coffee, strawberry milk and other beverages different substrates) with Hexane, and then detected by GC/MS with external standard method. Results The linearity was obtained among 0.1~1.0μg/mL with correlation coefficients above 0.9999. The recoveries of all artificial musk were in the range from 81.3% to 97.5% at the spiked levels of 20, 200, and 400 μg/kg in beverages, and the relative standard deviations (RSDs) were between 2.5%~7.5%. The limits of detections (LODs) of the 4 kinds of musk were 5.0 μg/kg. Conclusion The method is simple, rapid and accurate, and suitable for the simultaneous analysis and evidence of 4 artificial musk in beverages.
