利用电喷雾液质联用法快速检验血中佐匹克隆。少量血液样品采用乙腈沉淀蛋白后直接取上清液进样,使用Allure PFP Propyl(5μm,100mm×2.1mm)柱,流动相:乙腈:10mmol/L 乙酸铵-0.1%甲酸缓冲液=70:30进行分离,经电喷雾离子源正离子化后通过三重四级杆质谱多反应监测(MRM)对佐匹克隆(m/z 389.3/345.4和m/z 389.3/245.2)进行定性分析。被害人血中检出佐匹克隆成分。液质联用法检验血中佐匹克隆快速、准确、简单,可用于案件中检测血中佐匹克隆成分。

Zopiclone, one kind of new generation of sedative-hypnotic of the cyclopyrrolone compounds, has different chemical structures and different pharmacological function from that of the first and second generations of the hypnagogue like barbitals and benzodiazepines. Recently, in a robbery case, the suspects utilized the zopiclone to anesthetize the victims. In our laboratory, the blood sample of the victim was treated with acetonitrile to precipitate the proteins and the supernatant was separated through an Allure PFP Propyl column (5μm, 100mm×2.1mm) with the mobile phase containing acetonitrile (diluted to 70% by the buffer of 10mmol/L ammonium acetate mixed with 0.1% formic acid). The AB Sciex 4000Qtrap mass spectrometer equipped with an electro-spraying ionization source was used to detect two ion combinations of m/z 389.3/345.4 and m/z 389.3/245.2 by multiple reaction monitoring (MRM) for qualitative analysis of zopiclone. Finally, zopiclone was detected in the blood of the victims.
