我们开发了一种灵敏和特异性的检测方法,用于同时测量生物体液中的可卡因、可卡因乙烯及其六种代谢产物和脱水爱贡碱甲酯(一种热解产物)。该测定涉及固相萃取柱含有一个共聚键合相分离可卡因分析物,衍生与N,O-双(三甲基甲硅烷基)三氟乙酰胺和10 g/L的三甲基氯硅烷,和测量与气相色谱-质谱法操作在选择离子监测模式。分析物的检测器响应在3.1-1000 μ g/L的浓度范围内呈线性。可卡因、芽子碱甲酯和苯甲酰芽子碱的检测限约为1 μ g/L,其余分析物的检测限为3-6 μ g/L。提取和测定过程中可卡因的水解和脱水乙酰胆碱甲酯的伪影形成<1%。根据生物体液和测量时间的不同,钴及其衍生物在血浆、唾液和尿液中的比例不同。每种生物流体都提供了关于可卡因在人类受试者中的处置的独特信息。
We developed a sensitive and specific assay for the simultaneous measurement of cocaine, cocaethylene, six of their metabolites, and anhydroecgonine methyl ester, a pyrolysis product, in biological fluids. The assay involves solid-phase extraction columns containing a copolymeric bonded phase for isolation of cocaine analytes, derivatization with N,O-bis(trimethylsilyl)trifluoroacetamide and 10 g/L trimethylchlorosilane, and measurement with gas chromatography-mass spectrometry operating in the selected-ion monitoring mode. Detector responses for analytes were linear over a concentration range of 3.1-1000 micrograms/L. The limits of detection were approximately 1 microgram/L for cocaine, ecgonine methyl ester, and benzoylecgonine and 3-6 micrograms/L for the remaining analytes. Hydrolysis of cocaine and artifact formation of anhydroecogonine methyl ester during extraction and assay was < 1%. Cocaine and its derivatives appear in different proportions in plasma, saliva, and urine according to the biological fluid and time of measurement. Each biological fluid provides unique information on the disposition of cocaine in human subjects.
