摘要 目的: 研究甘草提取物对祖师麻主要活性成分瑞香素大鼠体内药代动力学特征参数的影响,探索其配伍用药的合理性。 方法 :大鼠分别灌胃给药瑞香素和含有同等剂量瑞香素的甘草提取物,LC-MS分析测定血浆中瑞香素浓度,经DAS 2.1.1程序处理数据。 结果 :甘草提取物能够减小瑞香素t1/2,tmax和Ke,增加Ka和AUC0-∞ 。 结论 :甘草能促进祖师麻中瑞香素的口服吸收,减慢其消除,提高其生物利用度。 Objective : To research the influence of glycyrrhiza extract on the pharmacokinetics characteristic parameters of daphnetin, which was aimed to explore the rationality of concert application of drugs. Method : The rats received intragastric administration of daphnetin and glycyrrhiza extract containing the same daphnetin respectively. The blood concentration of daphnetin was assayed by LC-MS. The data was processed by program DAS2. 1. 1. Result : Glycyrrhiza extract can reduce the t1/2, tmax and Ke of daphnetin, while increased the Ka and AUC0~ ∞. Conclusion : Glycyrrhiza extract promoted the oral absorption of daphnetin, slowed down the elimination and increased the biological availability.
