To establish a method for the determination of the concentration of Jujuboside A (JuA) in rat plasma by liquid chromatography-mass/mass spectrometry (HPLC-MS/MS), and study its pharmacokinetics. The rats were intravenously (4 mg/kg) or oral (20 mg/kg) administrated JuA. Blood samples were drawn from the palpebra at different stages. The concentrations of JuA in the plasma were determined by the HPLC-MS/MS method. Chromatographic separation was carried out with a security guard Waters YMCTM ODS-AQ S-5 120A (2.0 ×100 mm) (Waters, USA). HPLC-MS/MS was performed on a triple-quadrupole mass spectrometry equipped with electrospray ionization (ESI) and negative multiple reaction monitoring (MRM). The mobile phase consisted of methanol-water-formic acid (50∶50∶0.1), delivered at the flow rate of 0.3 mL/min under 30℃. The method was linear over the concentration range of 40 ng/mL-4 000 ng/mL (r2=0.999 1). The relative standard deviations of the assay were less than 15.0%for the low, and the recovery of the method was more than 85 %. The pharmacokinetic parameters were as follows: Ke 0.28/h,t1/2 2.55 h,AUC0→t 2 839.89 h·ng/mL, AUC0→∞3 201.51 h·ng/mL in rat with intravenous administration, and Ke 0.51/h,t1/21.35 h,AUC0→t 206.02 h·ng/mL, AUC0→∞211.13 h·ng/mL in rat with oral administration. The bioavailability of JuA was 1.32%. The developed method was successfully applied to the estimation of the pharmacokinetic parameters of JuA.
