Abstract: A high throughput screening method based on ultra performance liquid chromatogramphy-triple quadrupole composite linear ion trap mass spectrometry(UPLC-Q-TRAP/MS)was developed for the simultaneous and rapid confirmation of 49 common hypnotic and sedutive drugs. The pre-treatment method was based on solid-supported liquid liquid extraction(SLE). Waters C18 chromatographic column(2.1 mm×50 mm, 1.7 μm)was selected, with 0.1%(V/V)formic acid,5 mmoL/L ammonium acetate aqueous solution and methanol as mobile phases for gradient elution. The calibration curves showed good linearity in the range of 0.1~200.0 ng/mL,with correlation coefficients(R²)greater than 0.99 for all 49 analytes. The limits of highest detection and highest quantification of the 49 compounds were 0.1 ng/mL and 0.5 ng/mL, respectively. At spiked levels of 50、100、200 ng/mL, recoveries, intra-day precisions, and inter-day precisions of the 49 compounds were 65.9%~109.0%, 2.0%~17.6%, and 2.0%~16.3%, respectively. The established method is suitable for screening and testing these compounds in biological samples.- DOI:10.3969/j.issn.1000-1565.2023.02.008超高效液相色谱-三重四极杆串联质谱法检测全血中常见安眠镇静类药物方雅莉¹,马骥²(1.广东医科大学 科研平台服务管理中心,广东 东莞 523000;2.东莞市公安局 物证鉴定中心,广东 东莞 523000)摘 要:建立了超高效液相色谱-三重四极杆复合线性离子阱质谱快速筛查确证全血中49种安眠镇静类药物. 样品前处理采用固相支撑液液萃取法. 色谱条件:色谱柱为Waters C18(2.1 mm×50 mm,1.7 μm),以5 mmol/L乙酸铵-(体积分数为0.1%)甲酸水溶液(A),甲醇(B)为流动相,进行梯度洗脱. 在0.1~200.0 ng/mL内,49种常见药物展现出良好的线性关系(R²>0.99),最高检出限为0.1 ng/mL;最高定量限为0.5 ng/mL;全血基质中50、100、200 ng/mL 3个加标水平下回收率为65.9%~109.0%,日内精密度为2.0%~17.6%、日间精密度为2.0%~16.3%. 该方法可应用于生物检材中49种常见安眠镇静物质的检测.关键词:安眠镇静类药物;超高效液相色谱串联质谱;全血中图分类号:O657.7 文献标志码:A 文章编号:1000-1565(2023)02-0163-08Determination of common hypnotic and sedutive drugs in whole blood by UPLC-MS/MSFANG Yali¹, MA Ji²(1.
