摘      要：Objective:To simultaneously investigate the pharmacokinetics of gentiopicroside,sweroside,and swertiamarin,which are constituents of Gentianella acuta,by developing and validating a simple,sensitive,and fast ultra-high-performance liquid chromatography–tandem mass spectrometry *** and Methods:Blood samples were collected from the forward limb veins of six beagle dogs following oral gavage with ***,the whole plant extract(39.90 mg/kg).Plasma samples were processed using liquid–liquid *** analytes and paeoniflorin(internal standard[IS])were separated using an Acquity?UPLC ethylene bridged hybrid amide column(2.1 mm×100 mm,1.7μm)with isocratic elution using a mobile phase consisting of acetonitrile and 0.1%formic acid in water(80:20,v/v)at a flow rate of 0.4 mL/*** was performed using multiple reaction monitoring of the fragmentation transitions at m/z 401.1→179.0,403.1→195.0,419.1→179.0,and 525.2→449.1 for gentiopicroside,sweroside,swertiamarin,and the IS,***:The linearity of the analytical response was good and the calibration curves were linear over concentration ranges of 1.20–192.0,0.40–159.0,and 0.20–209.3 ng/mL for gentiopicroside,sweroside,and swertiamarin,*** extraction recovery was in the range of 84.72%–91.34%,84.58%–93.43%,and 82.75%–91.37%for gentiopicroside,sweroside,and swertiamarin,***:The method was successfully used to evaluate the pharmacokinetic parameters of gentiopicroside,sweroside,and swertiamarin in beagle dogs.
