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.
