摘要
目的针对滥用药物分析鉴定实践中亟待解决的问题,开展LC-MS/MS分析生物检材中吗啡类生物碱的应用研究。方法满足不同的鉴定需要,分别建立血液、尿液、唾液和头发等生物检材的样品前处理方法,确定同时分析海洛因、单乙酰吗啡、吗啡、可待因、乙酰可待因、二氢可待因酮和氢吗啡酮等吗啡类生物碱的LC-MS/MS方法。将方法应用于实际案例。结果所建立的方法对吗啡类生物碱分离良好。尿液稀释法、尿液提取法和头发中吗啡的最低检测限(LOD)分别为10ng/mL、0.01ng/mL和0.01ng/mg。结论所建立的方法简便、快速、特异性强、灵敏度高。目标物中加入二氢可待因酮和氢吗啡酮扩大了方法的实用范围。
Objective Liquid chromatography-tandem mass spectrometry（LC-MS/MS） was developed for the determination of opiates in biological samples according to the emerging problem in drugs abuse. Methods Opiates such as heroin, 6-acetylmorphine, morphine, codeine, acetyleodeine, hydroeodone and hydromorphone were isolated from human blood, urine, oral fluid and hair using a simple extraction and consequently analyzed using LC-MS/MS. The method was evaluated by real cases. Results The mobile phase give the optimum separation for opiates. The detection limit of morphine in urine with dilution and liquid-liquid extraction and in hair is 10ng/mL, 0.01 ng/mL and 0.01 ng/mg, respectively. Conclusion The method is simple and rapid, offering superior sensitivity and selectivity for opiates. The target compounds comprising hydrocodone and hydromorphone enlarge the applied area.
