芍药甙的药代动力学研究

THE STUDIES ON PHARMACOKINETICS OF PAEONIFLORIN

芍药是白芍的主要成份,狗iv芍药甙11.25mg/kg后,血药浓度曲线符合二室模型。动力学参数:T_(1/2)(α)为6.29±1.80min,T_(1/2)(β)为133.41±84.89min,VB为0.54±0.10L/kg,CL为3.41±1.01ml/kg·min^(-1)。本品静注后迅速以原型出现于尿中,前20min和7h尿中累积排泄量占静注量分别为36.85%和79.33%,7h胆汁中累积排泄量占静注量为3.77%

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 (α) was 6.29± 1.80min T1/2 ( β ) was 133.41±84.89 min, VB was 0.54 ± 0.10 L/kg, and CL was 3.41 ± 1.01ml/min·kg-1 . The results also were shown that PF was rapidly removed from the ...
