| 摘 要： | 目的 研究甘草酸及其代谢产物甘草次酸对芍药中主要活性成分芍药苷在大鼠体内药动学特征的影响，探索芍药与甘草配伍用药的合理性。方法 大鼠单独ig给予芍药苷或分别与甘草酸、甘草次酸联合用药，于不同时间点采集血样，LC-MS测定芍药苷血药浓度，建立药物浓度-时间曲线，采用DAS2.1.1软件计算、分析药动学参数。结果 甘草酸能减小芍药苷Cmax、tmax，降低芍药苷AUC；甘草次酸能增加芍药苷Cmax、tmax，显著提高芍药苷AUC。结论 甘草提高芍药苷生物利用度可能与甘草酸的代谢产物甘草次酸的作用相关。

| Abstract: | Objective To explore the potential effects of glycyrrhizic acid and its active metabolite glycyrrhetinic acid on the in vivo pharmacokinetic parameters of paeoniflorin in rats, and to investigate the rationality of the compatibility of Paeonia lactiflora and Glycyrrhizae Radix et Rhizome. Methods After the ig administration of paeoniflorin alone or with glycyrrhizic acid and glycyrrhetinic acid respectively, blood samples were collected at different time points and assayed by LC-MS, and the plasma concentration-time profiles of paeoniflorin were established. The pharmacokinetic parameters were calculated and analyzed with DAS2.1.1 software. Results Glycyrrhizic acid could reduce the Cmax, tmax, and AUC of paeoniflorin, while glycyrrhetinic acid could increase the parameters. Conclusion Glycyrrhizae Radix et Rhizome could increase the bioavailability of paeoniflorin through the activity of glycyrrhetinic acid which is the active metabolite of glycyrrhizic acid. |
