摘要: 目的:建立检测麝香酮在灌胃人工麝香大鼠体内的血药浓度的分析方法,用于人工麝香的药动学研究。方法:血浆样品以乙醚液-液萃取法进行前处理,采用超高效液相色谱与串联四级杆飞行时间质谱仪联用技术(UPLC/Q-TOFMS)进行分析。 ACQUITY UPLC BEH C18色谱柱(2.1 mm×100 mm,1.7 μm),柱温 35 ℃,流动相为乙腈:水(均含0.1%的甲酸85∶15),流速 0.2 mL/min。使用APCI离子源,正离子模式下采集数据。结果:麝香酮血浆浓度在 0.0756~3.78 μg/mL 范围内线性关系良好(R=0.9980),最低检测限为 0.05 μg/mL。高、中、低三种浓度的准确度和精密度均符合生物样品检测要求(RE<10%,RSD<15%),平均绝对回收率均>81%。结论:本实验所建立的方法稳定可靠,专属性强,灵敏度较高,测定方便快速,适用于人工麝香中麝香酮的临床前血药浓度分析。

Abstract: AIM: To develop a method for the determination of muscone in plasma of the rat administered by artificial-musk. METHODS: Sample was prepared by liquid-liquid extraction,which was chromatographed on ACQUITY UPLC/Q-TOFMS with a ACQUITY UPLC BEH C18(2.1 mm×100 mm,1.7 μm)column at 35 ℃. The mobile phase was 85% acetonitrile with 0.1% formic acid-15% 0.1%FA at the flow rate of 0.2 mL/min. APCI ion source was used and data was collected at positive ion mode. RESULTS: A good linear relationship was obtained between the peak area ratio of muscone(R=0.9980) and the concentration of muscone over the range of 0.0756 to 3.78 μg/mL. The limit of quantitation was 0.05 μg/mL. Accuracy and precision of all concentrations meet the biological sample testing requirements(RE<10%,RSD<15%). Average absolute recovery was bigger than 81%. CONCLUSION: The method was reliable, stable, special and suitable for the study of preclinical pharmacokinetics of artificial-musk.
