摘　　要：目的使用实时直接分析-串联质谱,建立快速检测人血中的JWH-018、JWH-250和AM-2201的方法。方法用乙腈-甲醇(4:1)沉淀蛋白的方法对血样进行简单前处理,采用DART 12Dip-it自动进样系统,以正离子、MRM模式进行分析。结果血液中JWH-018、JWH-250、AM-2201可以得到有效检测,在0.02-5.00μg/m L线性关系良好,相关系数均大于0.99,检出限分别为0.016μg/m L,0.003μg/m L和0.017μg/m L,日内、日间RSD均小于15%。结论本文所建方法灵敏度高,准确性较好,方法省时省力,可用于实际案例血液中合成大麻素JWH-018、JWH-250、AM-2201的分析。Objective To establish a method for rapid detection of JWH-018, JWH-250 and AM-2201 in blood by direct analysis in real-time coupled with tandem mass spectrometry. Methods These samples were extracted by acetonitrile-methanol（4：1）, using DART 12Dip-it automatic sampling system. They were analyzed by positive ion and MRM mode. Results The detection limits of JWH-018, JWH-250 and AM-2201 were in good linearity in the range of 0.02-5.00μg/m L. The correlation coefficients were above 0.99 and the detection limits were 0.016μg/m L, 0.003μg/m L and 0.017μg/m L, respectively. The intra-day and inter-day RSD were less than 15%. Conclusion The method has the advantages of high sensitivity and good accuracy. The sample processing is simple and can be analyzed in short time. This method is suitable for the analysis of JWH-018, JWH-250 and AM-2201 in practical cases.
