摘要: 建立HPLC-MS/MS法测定大鼠血浆和组织样品中芍药苷和芍药内酯苷, 研究白芍总苷在大鼠体内的药代动力学和组织分布特征。采用固相萃取法进行样品处理, 色谱柱为C18, 流动相为乙腈-0.05%甲酸溶液 (20:80, v/v), ESI, 负离子多反应监测模式。方法学验证结果均符合要求。白芍总苷灌胃给与大鼠后, 主要成分芍药苷和芍药内酯苷迅速吸收并达到峰值, 二者具有相似的药动学特征, 在组织中分布广泛, 并可透过血脑屏障。

Abstract:

A simple, sensitive and specific high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method combined with solid phase extraction has been developed and validated for the simultaneous quantification of paeoniflorin and albiflorin in rats plasma and tissue homogenate after administration of total glycosides of paeony (TGP). Chromatographic separation was achieved on a C18column (150 mm×4.6 mm, 5 μm) with mobile phase consisted of acetonitrile0.05% formic acid aqueous (20: 80, v/v) at a flow rate of 0.5 mL/min. The analytes were detected with triple-quadrupole mass spectrometer using turbo ion spray with negative ionization in the multiple reaction-monitoring (MRM) modes. The results of method validationconformed to the requirements for the determination of biological samples. This method was successfully applied to the pharmacokinetics and tissue distribution study of TGP in rats. The results showed that paeoniflorin and albiflorin were absorbed and reached peak value quickly, and had the similar pharmacokinetic characteristics. Both of them underwent a rapid and wide distribution in the tissues throughout the whole body, among which stomach was the main distribution tissue. Moreover, they had the ability to cross the blood-brain barrier.
