摘要:

目的 建立液相色谱-串联质谱(LC-MS/MS)定量检测血浆紫杉醇的方法,并进行基本分析性能验证。方法 采用 LC-MS/MS定量检测血浆样本中的紫杉醇含量。色谱系统使用超高压液相色谱,流速为0.3 mL/min,质谱采用多反应监测(MRM)模式进行定量。紫杉醇及其氘代内标(PTX-D5)的离子对分别为876.4>308.2和881.5>313.2。参照美国食品与药品监督管理局(FDA)的生物分析方法验证导则标准对建立的LC-MS/MS进行线性、检出限、精密度和准确度等基本性能验证。结果 LC-MS/MS检测血浆紫杉醇的线性范围为10~1 000 ng/mL,定量检出限为10 ng/mL,批内、批间变异系数(CV)分别为≤4.2%和≤8.9%,准确度为88.7%~104.0%。结论 建立的LC-MS/MS基本性能符合评价标准,能够灵敏且准确地检测血浆紫杉醇含量。

Abstract:

Objective To establish a liquid chromatography-tandem mass spectrometry(LC-MS/MS)for the quantitative determination of plasma paclitaxel,and to evaluate its performance. Methods Plasma paclitaxel was determined quantitatively by LC-MS/MS. High performance liquid chromatography was used. The flow speed was 0.3 mL/min. Multiple reaction monitoring (MRM) was used for quantitative determination. The ion pairs of paclitaxel and PTX-D5 were 876.4>308.2 and 881.5>313.2,respectively. According to U.S. Food and Drug Administration (FDA) guideline about bioanalytical method validation,the general analytical performance validation was performed for linearity,detection limit,precision and accuracy. Results The linearity was 10-1 000 ng/mL. The detection limit was 10 ng/mL. Within-run and between-run coefficients of variation (CV) were ≤4.2% and ≤8.9%,respectively. The accuracy was 88.7%-104.0%. Conclusions The performance of established LC-MS/MS meets evaluation standards,and the assay is accurate and precise for the determination of paclitaxel.
