Abstract:
Aims To establish a UPLC-MS method for quantifying protocatechuie acid,kaempferol-3-O-β-D-glucoside and quercitrin and to investigate the pharma-cokinetics of three indix components in flower of Poly-gonumorientale L.in rat plasma.Methods The anal-ysis was achieved by BEH C18 column (2.1 mm ×100 mm,1.7 μm)with a mobile phase composed of 0.1%formic acid using step gradient elution.A TQD tandem mass spectrometry equipped with electrospray ionization source was used as detector and operated by selected ion recording(SIR)mode.Results In the selected linear range,calibration curves of the three markers components showed good linearity.Extraction recovery rate,precision,accuracy and stability reached the de-termination request.The parameters of Tmax (h ) in three index components were 0.46 ±0.1,0.79 ±0.33 and 2.63 ±4.6,respectively;Cmax (μg·L -1 )in three index components were 463.8 ±207.81,18.53 ±7.82 and 137.38 ±71.09,respectively.Conclusion The fully validated UPLC-MS method has been successfully applied to the pharmacokinetic study of the three index components in flower of Polygonumorientale L.in rat plasma.
