摘要: 目的 建立GC-MS同时测定血液中苯海索、氯丙嗪和氯氮平的方法。 方法 血液中加入内标SKF525A,在pH>10条件下用V(苯)﹕V(乙酸乙酯)=1﹕1提取,用GC-MS全扫描法进行定性检测;以地西泮-d5为内标,样品在pH>10条件下用V(苯)∶V(乙酸乙酯)=1∶1提取,用GC-MS选择离子监测方法进行定量检测。 结果 苯海索、氯丙嗪和氯氮平在20~10 000 ng/mL范围内呈线性关系,最小检测限分别为0.3、0.3和0.7 ng/mL(信噪比≥3),方法回收率为79.9%~85.5%,日内、日间精密度均小于5.1%。 结论 本方法可同时分析血液中苯海索、氯丙嗪和氯氮平,方法灵敏度高、快速、操作简便,适用于苯海索、氯丙嗪和氯氮平的血药浓度监测和急性中毒案件的检测。

Abstract: Objective To develop a method to measure trihexyphenidyl, chlorpromazine and clozapine in human blood with GC-MS. Methods The specimens were alkalized(pH>10) and extracted with V(benzene)∶V(ethyl acetate)=1∶1, and qualitatively analyzed using GC-MS-Full Scan with internal standard SKF525A. The specimens were alkalized(pH>10) and extracted with V(benzene)∶V(ethyl acetate)=1∶1, and quantitatively analyzed using GC-MS-SIM with internal standard diazepam-d5. Results The lowest detection limits of trihexyphenidyl, chlorpromazine and clozapine were 0.3, 0.3 and 0.7 ng/mL(S/N≥3) respectively. The calibration curve in 20-10 000 ng/mL showed a good linear distribution. The recovery rate was 79.9% to 85.5%. The RSDs of intraday and interday were less than 5.1%. Conclusion The established method was simple, sensitive and accurate for simultaneous determination of trihexyphenidyl, chlorpromazine and clozapine in human blood, and can be applied in forensic toxicological cases.
