摘要:

建立大鼠血浆中杨芽黄素的高效液相色谱串联质谱定量分析方法,考察大鼠灌胃给药后,杨芽黄素在其体内的药动学特征。血浆样品经乙腈试剂沉淀蛋白后,取上清液5 μL进样分析。珊瑚菜内酯作为内标物质,采用高效液相色谱串联质谱分析方法,检测大鼠血浆中杨芽黄素的浓度。选择色谱柱为Zorbax Eclipse Plus C18柱(2.1 mm×50 mm, 1.8 μm),流动相为乙腈-0.1%甲酸水溶液(体积比60:40)梯度洗脱;采用电喷雾离子源,在正离子模式下的选择性反应离子监测m/z 268.8→225.9 (杨芽黄素)和m/z 300.9→233.0 (内标杨芽黄素)。杨芽黄素在0.5~200.0 ng/mL范围内线性关系良好;日间、日内精密度相对标准偏差为3.28%~13.12%,准确度相对误差-6.38%~7.60%;基质效应为98.43%~103.57%;提取回收率为93.36%~96.31%。经方法学完整验证,该分析方法可用于大鼠血浆中杨芽黄素的测定及其药动学评价研究。

Abstract:

The aim was to develop a method using high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) for the quantitative analysis of tectochrysin in rat plasma and evaluate the pharmacokinetics of tectochrysin in rats after intragastric administration. First, plasma samples were precipitated using acetonitrile reagent, and a 5 μL supernatant was injected into system for analysis. Phellopterin was used as the internal standard to monitor the concentrations of tectochrysin in rat plasma via HPLC-MS/MS. Zorbax Eclipse Plus C18 column (2.1 mm × 50 mm, 1.8 μm) was used, and the mobile phase was composed of an aqueous solution (60:40, V/V) of 0.1% acetonitrile and formic acid (isocratic elution). Electrospray ionization was used in the positive ion mode, and selected reaction monitoring was performed at mass-to-charge ratio (m/z) 268.8→225.9 (tectochrysin) and m/z 300.9→233.0 (internal standard). The calibration curve was linear in the range of 0.5~200 ng/mL. The relative standard deviation of inter and intraday precisions was 3.28%~13.12%, and relative error of accuracy was -6.38%~7.60%. Matrix effect was 98.43%~103.57%, and extraction recovery rate was 93.36%~96.31%. The assay was found to be useful for determining the concentration and evaluating the pharmacokinetics of tectochrysin in rat plasma.
