1、平胃散中苍术素在大鼠体内药代动力学探究 李古月1,2刘佳鑫1,2才谦31.中国医科大学附属第一医院,辽宁沈阳110000;2.中国医科大学药学院,辽宁沈阳110000;3.辽宁中医药大学药学院,辽宁大连116600[摘要]目的研究平胃散中苍术素在大鼠血浆及组织中分布特征。方法建立大鼠血浆中苍术素的HPLC测定方法,考查大鼠口服平胃散混悬液0.17,0.33,0.5,1.0,2.0,3.0,4.0,6.0,8.0,12,24h后血药浓度变化和2,3,8h后大鼠体内组织分布情况,采用DAS2.0数据处理软件计算药代动力学参数。结果大鼠口服平胃散混悬液后,苍术素在大鼠体内的达峰时间T
2、max为2.5h,最大浓度Cmax为1.765mg/L,半衰期t1/2z为5.723h,AUC11.789mg/L·h,且在6h左右时第2次达峰,出现双峰现象。大鼠口服平胃散混悬液后2,3,8h的药物组织分布由高到低的顺序大致是胃>小肠、脾>肝、肺、心>肾、大肠。结论该方法灵敏、快速、准确,可用于大鼠血浆中苍术素浓度的测定。[关键词]平胃散;苍术素;药代动力学;组织分布;高效液相色谱13[中图分类号]R285[文献标识码]A[文章编号]1673-7210(2014)03(b)-0019-04DeterminationofAtractylodinofPingweiPowderinr
