Abstract:
We first report the pharmacokinetics of paeoniflorin ( PF), that is a main component of paeony roots, in dogs by HPLC analysis. The experimental results were shown that after i .v . of 11.25 mg/kg PF in 4 dogs, the curve of plasma concentrations versus times for PF was fitted well to a open 2 compartment model, the T1/2 (?) was 6.29?1.80min T1/2 ( ? ) was 133.41?84.89 min, VB was 0.54 ? 0.10 L/kg, andCL was 3.41 ? 1.01ml/min?kg-1 .The results also were shown that PF was rapidly removed from the blood by kidney and the accumulated recovery amounts of excretion was 36.85% and 79.33% of total i .v . doses during 20 min and 7h administrations respectively. The elimination of PF by liver was lower than by kidney, and the accumulated amount of PF in bile was only 3.77% within 7h after iv.
