title: Comparative pharmacokinetics study after oral administration of geniposide in normal rats and adjuvant-induced arthritis rats by UPLC-MS/MS.
abstract: A simple and rapid ultra-performance liquid chromatography-electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) method for quantitative analysis of geniposide (GE) in rat plasma was developed, validated and applied to determine the level of GE in rat plasma after oral administration of GE in adjuvant-induced arthritis (AA) and normal rats. The investigation showed that there were significant differences in the groups between the normal rat and AA rat in pharmacokinetics parameters, such as the area under the time versus drug concentration curve (AUC(0-∞)) (3.77 ± 0.68 versus 2.27 ± 0.42, p < 0.05), the apparent volume of distribution (V) (140.41 ± 2.07 versus 136.51 ± 1.03, p < 0.05), the mean residence time (MRT) (3.98 ± 0.90 versus 3.80 ± 0.50, p < 0.05) and the clearance from the total body (CL) (16.10 ± 2.87 versus 26.44 ± 4.94, p < 0.05). The results indicated that AA could alter the pharmacokinetics of the drug and these experimental findings could be useful for the further study of the clinical applications of GE.
