摘要: 介绍了一种用SEP-PAK固相萃取技术和HPLC同时检验尿液中的苯并二氮类药物硝基安定, 氯硝基安定和氟硝基安定的方法。使用的反相色谱柱为YMC A-303 C18, 以乙腈-0.01M醋酸铵(45:55, v/v)为流动相, 紫外检测波长为254 nm。各药物的回收率均大于80%; 日内和日间测定的变异系数为1~5%, 是一种精密、灵敏的方法。

Abstract: An efficient method of SEP-PKA solid-phase extraction and reversed-phase, isocratic high-performance liquid chromatographic method for the simultaneous quantitation of nitrazepam, clonazepam and flunitrazepam in human urine is presented. The recoveries with SEP-PAK C18 cartridgeswere excellent for all these drugs. The drugs were separated on a reversed-phase YMC A-303 C18 co-lumn with acetonitrile-0.01 mol/L ammonium acetate (45:55, v/v) as the mobile phase. The detectionwas performed at 254 nm. Within-day and day-to-day precision were about 1~5%. The method is sensitive and reproducible and can be used in clinical and experimental toxicokinetic studies.
