In the present study, a rapid, selective, and sensitive liquid chromatography-tandem mass spectrometry(LC-MS/MS) method was developed and validated to simultaneously determinate the plasma contents of 5 major constituents of TRQ, including chlorogenic acid(CHA), caffeic acid(CFA), baicalin(BA), ursodeoxycholic acid(UDCA) and chenodeoxycholic acid(CDCA) in rats after intravenous administration of TRQ. Chromatographic separation was performed on an Agilent Zorbax SB-C_(18) column(3.5 μm, 100 mm × 2.1 mm), with acetonitrile and 0.1% aqueous formic acid as mobile phase at a flow rate of 0.3 m L·min^(^(-1)). The calibration curves were linear over the ranges of 27.0–13 333.0 ng·m L^(-1) for CFA, 30.0–14 933.0 ng·m L^(-1) for CHA, 50.0–50 333.0 ng·m L^(-1) for BA, 550.0–55 000.0 ng·m L^(-1) for UDCA, and 480.0–48 000.0 ng·m L^(-1) for CDCA, respectively. Intra- and inter-day precisions(relative standard deviations, RSDs) were from 3.11% to 14.08%. The extraction recoveries were greater than 71% and accuracy(relative recovery) was from 89% to 137% for all analytes, except endogenous bile acids. This validated method was successfully applied to the first pharmacokinetic study of CFA, CHA, BA, UDCA and CDCA in rat plasma after intravenous administration of TRQ.展开更多

By combining the DAD spectrum and the accurate mass measurement of ESI-TOF/MS, twelve components in Tanreqing injection were identified. This study contributes to clarifying the nature of Tanreqing injection, and provides an effective and reliable process for the comprehensive and systematic characterization of complex traditional Chinese medicine preparations.展开更多
