Abstract

Objective: To develop a sensitive and reliable ultra performance liquid chromatography tandem mass spectrometry ( UPLC-MS / MS) method for simultaneous determination and pharmacokinetics of protocatechuic acid, kaempferol biotin glucoside and quercitrin in rat plasma, and study their pharmacokinetic characteristics in rats.

Methods: Three compounds were simultaneously determined by UPLC-MS / MS on Waters BEH C18( 50 mm × 2. 1 mm,1. 7 μm) column. The mobile phase was 0. 1% acetonitrile formic acid and0. 1% aqueous formic acid, and programmed in a linear gradient mode. The compounds were ionized in the electrospray ionization ion source of the mass spectrometer and detected in MRM mode.

Results: The t1 /2of protocatechuic acid,kaempferol biotin glucoside and quercitrin after intravenous injection were( 41. 9 ± 12. 3),( 71. 3 ± 56. 8) and( 90. 3 ± 74. 8) min. The Cmaxwere( 1. 7 ± 0. 7) μg / m L,( 2. 1 ± 0. 9) μg/m L,( 8. 7 ± 3. 7) μg/m L.

Conclusion: The established method is specific,rapid,accurate and sensitive,and is proved to meet the requirements of biological sample analyses,and is suitable for the concentration determination of protocatechuic acid, kaempferol biotin glucoside and quercitrin in rat plasma, three compounds are all best fitted to the two-compartment open pharmacokinetic model.
