摘要
目的:山葛降脂分散片和葛根分散片中葛根素在大鼠体内药代动力学的对比研究。方法:以香草醛为内标物,利用HPLC测定大鼠血浆中葛根素的含量。结果:山葛降脂分散片的主要药动学参数:Tmax(3.000±0.371)h,Cmax(3.159±0.415)mg·L-1,AUC0→∞(19.593±3.168)mg·L-1·h-1,MRT0→∞(11.370±2.358)h;葛根分散片的主要药动学参数:Tmax(4.000±0.313)h,Cmax(2.784±0.398)mg·L-1,AUC0→∞(17.605±3.993)mg·L-1·h-1,MRT0→∞(8.678±1.625)h。结论:山楂叶和葛根提取物合用能使葛根素的吸收加快,浓度增大,消除减慢。房室模型拟合分析为二房室模型。
Objective: To comparative research puerarin of Shange lipid-lowering dispersible tablets and Gegen dispersible tablets in rats in vivo pharmacokinetics.Method: With vanillin as internal standard,HPLC was used to determine the contents of puerarin in rat plasma.Result: The main pharmacokinetic parameters of Shange lipid-lowering dispersible tablets: Tmax(3.000 ± 0.371) h,Cmax(3.159 ± 0.415) mg·L-1,AUC0→∞(19.593 ± 3.168) mg·L-1.h-1,MRT0→∞(11.370 ± 2.358) h;The main pharmacokinetic parameters of Gegen dispersible tablets: Tmax(4.000 ± 0.313) h,Cmax(2.784 ± 0.398) mg·L-1,AUC0→∞(17.605 ± 3.993) mg·L-1·h-1,MRT0→∞(8.678 ± 1.625) h.Conclusions:The extract of Hawthorn leaves and Pueraria combination can speed up the absorption of puerarin,the concentration increases and elimination of slow down.By the analysis of compartment model,it is two compartment model.
