Abstract: 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.
