摘要:

建立大鼠血浆中异绿原酸BLC-MS/MS测定方法,研究大鼠口服异绿原酸B后的血浆药代动力学特征。血浆样品中加入内标白藜芦醇后经甲醇沉淀蛋白。HPLC分离采用Zorbax SB-C18 (3.5 μm, 2.1 mm×100 mm),流动相为含0.1%甲酸的甲醇,流速为0.2 mL/min。质谱检测采用电喷雾离子源,负离子选择反应监测(SRM)模式检测m/z515.3→352.9 (异绿原酸B)m/z227.1→143.1(白藜芦醇,内标)。标准曲线在5–2500 ng/mL范围内线性良好(r2 = 0.9982), 日内、日间精密度(RSD)小于12.46%,准确度在±5.80%范围内,血浆样品稳定性好。该方法已成功应用于大鼠血浆异绿原B的药代动力学研究。结果表明,5–20 mg/kg剂量范围内,异绿原酸B在大鼠体内呈非线性的药代动力学特征。

Abstract:

Asensitive LC-ESI-MS/MS method for determination of isochlorogenic acid B in rat plasma was developed and validated in the present study. Plasma samples were prepared by a simple protein precipitation with methanol containing resveratrol as internal standard (IS). The chromatographic separation was performed on a Zorbax SB-C18 column (3.5 μm, 2.1 mm×100 mm, Agilent, USA) at a flow rate of 0.2 mL/min using methanol/water containing 0.1% formic acid (v/v) as mobile phase. The detectionwas performed on a triple quadrupole tandem mass spectrometer equipped with Electronic Spray Ion by selected reaction monitoring (SRM) of the transitions at m/z 515.3→352.9 for isochlorogenic acid B and m/z 227.1→143.1 for IS, respectively. The calibration curve of the method was linear over the range of 5–2500 ng/mL (r2 = 0.9982). The intra- and inter-day precisions (R.S.D.%) were less than 12.46%, and the accuracy (R.E.%) was within ±5.80%. Isochlorogenic acid B was sufficiently stable under all relevant analytical conditions. The validated method was successfully applied to the plasma pharmacokinetic studies of isochlorogenic acid B in rats. It was found that isochlorogenic acid B had non-linear pharmacokinetic characteristics in rats within the dosage ranges from 5 to 20 mg/kg.
