建立了一种快速多滤过型净化柱(MPFC)-QuEChERS结合气相色谱-串联质谱(GC-MS/MS)检测血液中,γ,-羟基丁酸(GHB)的新方法。通过考察样品前处理条件与仪器条件对检测结果的影响,确定了最优实验条件:0.1 mL血液样品中加入GHB-D,6,作为内标,以乙酸乙酯为萃取剂,上清液过MPFC-QuEChERS净化柱后挥干,经N,O-双三甲基硅烷基三氟乙酰胺(BSTFA)衍生化,在多反应监测(MRM)模式下分析。结果表明,血液中GHB在0 ~ 1 000 ng/mL质量浓度范围内线性关系良好,相关系数(,r,2,)为0.995 1,检出限和定量下限分别为0.2、0.5 ng/mL,日间和日内相对标准偏差(RSD)均小于15%,回收率为80.1% ~ 84.7%,基质效应为87.4% ~ 94.4%。该方法由传统液液萃取法改进优化,稳定性好、灵敏度高,能够快速有效测定实际案件血液样品中的GHB含量。
A new method was developed for the determination of ,γ,-hydroxybutyric acid(GHB) in human blood by gas chromatography-tandem mass spectrometry(GC-MS/MS) with a kind of purification column(MPFC-QuEChERS).Effects of sample pretreatment conditions and analytical instrument conditions on the test results were investigated in the round,and the optimal experimental conditions were determined. First of all,GHB-D,6, was spiked into 0.1 mL blood sample as the internal standard,and then the analyte was extracted using ethyl acetate efficiently.After that,the supernatant was allowed to flow through the MPFC-QuEChERS purification column and evaporated to dryness.Finally,the dried residue was derivated with trifluoroacetamide(BSTFA) and analyzed in multi-reaction monitoring(MRM) mode.Experimental results showed that there were linear relationships for the spiked human blood samples in the range of 0-1 000 ng/mL(,r,2 ,>, 0.995 1).The limits of detection(LOD) and limits of quantitation(LOQ) of the method were 0.2 ng/mL and 0.5 ng/mL,respectively.The inter-day relative standard deviations(RSD) and intra-day RSD were both less than 15%.An extraction recovery of 80.1%-84.7% was obtained for the spiked human blood samples.The matrix effect ranged from 87.4% to 94.4%.The results indicated that the developed method was improved and optimized by traditional liquid-liquid extraction method,it could be applied to the rapid and effective determination of GHB in human blood samples of actual cases with its good stability and high sensitivity.
