| 摘 要： | 目的 考察聚乙二醇400 (PEG400)对黄芩苷在大鼠体内药动学的影响.方法 将大鼠随机分为黄芩苷组和PEG400组,黄芩苷组大鼠单独灌胃给予黄芩苷,PEG400组的灌胃给予黄芩苷和PEG400混合物,于不同时间点取静脉血,用HPLC法检测血浆中的黄芩苷,绘制药时曲线,用DAS 2.0计算药动学参数.结果 黄芩苷的线性范围为0.3203 ～ 10.25 μg·mL-1,定量下限为0.3203 μg· mL-1,日内、日间RSD均＜10％,提取回收率＞85％,PEG400组的AUC0-t明显高于黄芩苷组.结论 PEG400可促进黄芩苷在大鼠体内的吸收.

| Abstract: | OBJECTIVE To ivestigate the effect of polyethylene glycol 400 (PEG400) on the pharmacokinetics of baicalin in rats.METHODS The rats were randomly divided into baicalin group and polyethylene glycol 400 group.Concentration of baicalin in plasma was contented at the different time by HPLC,the concentration-time curve was created,and pharmacokinetic parameters were calculated by DAS 2.0.RESULTS The linear range of baicalin was 0.3203-10.25 μg · mL-1,lower limit of quantification was 0.3203 μg·mL-1,RSD were less than 10％.Extraction recovery were ＞ 85％.AUC0-t from PEG 400 was significantly higher than that of the baicalin group.CONCLUSION PEG400 can enhance the bioavailability of baicalin in the rats. |
