摘　　要：目的研究毛冬青皂苷(ilexsaponin A1)静脉给药后在大鼠体内的药物动力学特性。方法大鼠尾静脉注射给予毛冬青皂苷ilexsaponin A1(30 mg/kg),用HPLC法测定血药浓度,采用DAS2.0软件分析其药代动力学参数。结果大鼠静脉给药后,ilexsaponin A1在体内呈二室模型分布,主要药代动力学参数为:t1/2(α)=3.542min,t1/(2β)=17.636 min,CL=0.02 L.min-1.kg-1,AUC(0→)t=1096 mg.min.L-1,tmax=5 min,Cmax=52.972 mg.L-1。结论该法可用于大鼠血浆中ilexsaponin A1的检测及其体内药物动力学研究;静脉给药后,ilexsaponin A1在大鼠体内分布和消除迅速。Objective To investigate the pharmacokinetic characteristics of ilexsaponin A1 in rats after intravenous injection.Methods The HPLC was applied to determine the plasma concentration of ilexsaponin A1 in rats after intravenous injection of ilexsaponin A1（30mg/kg）,and the pharmacokinetic parameters were calculated by DAS2.0 software.Results After intravenous injection of ilexsaponin A1 into the rats,the blood plasma concentration-time profiles of ilexsaponin A1 were fitted to the two-compartment model.The pharrnacokinetic parameters of ilexsaponin A1 activities were as follows： t1/2（α）=3.542 min,t1/2（β）=17.636 min,CL=0.02 L·min-1·kg-1,AUC（0→t）=1096 mg·min·L-1,tmax=5 min,and Cmax=52.972 mg·L-1.Conclusion The established HPLC method is appropriate for the determination and pharmacokinetic study of ilexsaponin A1 in rat plasma.After intravenous injection,ilexsaponin A1 is distributed and eliminated quickly in rats.
