Abstract:
Objective To establish a HPLC method for the determnation of serum concentration of isoimperatorin in rats and study pharmacokinetic characteristic of isoimperatorin in rat after drug admiaistraction. Method The concentrations of isoimperatorin in rats were determined after drug administration and the pharmacokinetic parameters of isoimperatorin were estimated by DAS2.0 computer program. Result The concentration-time profiles were fitted with open two compartment model system. The main pharmacokinetic parameters were as follows:Tmax =(1.6?0.000)h, Cmax =(15.842?0.35)mg/L, AUC0-t=(80.761?10.03)mg/(L?h), AUC0-∞=(89.45?9.34)mg/(L?h), t1/2=(5.101?0.24)h. Conclusion The method is appropriate for the determination and pharmacokinetic study of isoimperatorin in rats after drug administration.
