摘　　要：建立了减肥食品中违禁药物芬氟拉明、安非拉酮和马吲哚的定性和定量分析方法。样品用氯仿提取,HP 5MS毛细管色谱柱分离,扫描方式(scan)定性确证,选择离子方式(SIM)定量。结果表明,减肥食品中芬氟拉明、安非拉酮、马吲哚能在气相色谱 质谱联用仪上同时得到分析,与NIST98谱库比较,匹配度均在90%以上,说明该方法适用于减肥食品中这3种药物的确证分析和定量分析。A gas chromatography-mass spectrometry (GC/MS) analytical method for three anorectics drugs, fenfluramine, diethylpropion and mazindol, illegally adulterated in slimming foods has been developed. They can be simultaneously identified and quantified. The samples were extracted with chloroform, and then separated by GC with an HP-5MS GC capillary column. The temperature programming was started at 70 ℃. The temperature was held at this temperature for 2 min and then increased at 10　(℃/min) to 280 ℃. The completely separated peaks were identified by MS with a quadrupole mass filter and quantitated in selected ion monitoring mode. Compared with the NIST98 library, the matching qualities of the drugs in foods were all over 90%. The calibration curves of the drugs were excellent with correlation coefficients between (0.999 1) and (0.999 9), and relative standard deviations between 1.6% and 2.2%. The recoveries were between 96.0% and 102.4%. The results demonstrated that this method is suitable for the identification and quantitation of these anorectics drugs in slimming foods.
