Validation of an analytical method using UPLC-MS/MS to quantify four bioactive components in rat plasma and its application to pharmacokinetic study of traditional and dispensing granules decoction of Ziziphi Spinosae Semen.
A rapid and sensitive UPLC-MS/MS method was established for the simultaneous quantification of 6'''-feruloylspinosin, spinosin, jujuboside A, and jujuboside B in rat plasma after the oral administration of traditional and dispensing granules (DG) decoction of Ziziphi Spinosae Semen (ZSS). The four components were separated using 0.1% formic acid and acetonitrile as a mobile phase by gradient elution at a flow rate of 0.3 mL/min equipped with a C18 column (2.1 × 50 mm, 1.7 μm particle size, Acquity BEH C18 ). The mass spectrometer was operated under multiple reaction monitoring mode. ⋯ MRT0-t of jujuboside B was significantly increased. No significant variation was observed for the pharmacokinetic parameters of spinosin. The results could provide a scientific basis for the clinical application of traditional and DG decoction of ZSS.
