摘要: 研究地榆皂苷I在Caco-2细胞单层模型中的吸收机制。观察地榆皂苷I在Caco2细胞模型中的双向转运,考察时间、药物浓度、温度和抑制剂对地榆皂苷I吸收的影响。用HPLC检测药物浓度,计算其表观渗透系数(Papp)。结果显示,地榆皂苷I在Caco2细胞模型中,随时间和浓度的增加,药物吸收呈饱和趋势,且受温度和碘乙酰胺影响,但不受外排抑制剂维拉帕米和MK571的影响。结果表明,地榆皂苷I在Caco2细胞中的吸收主要是由载体介导的主动转运。

Abstract: To study the absorption of Ziyuglycoside I in human Caco2 cell monolayer model.Caco2 cellmonolayer model was applied to investigating the bidirectional transport of Ziyuglycoside I.The effects of time,drug concentration,temperature,and inhibitor on the absorption of Ziyuglycoside I were observed.Drug concentration was measured by HPLC and the apparent permeability coefficients (Papp) were calculated.Time and concentration saturation were observed for the absorptive transport of Ziyuglycoside I across Caco2 monolayers.The transport of Ziyuglycoside I was influenced by the change of temperature and the presence of iodoacetamide,but not Verapamil or MK571.The absorption and transport mechanismof Ziyuglycoside I in Caco2 cell monolayers are active transportation mediated by transporter.

Key words: Ziyuglycoside I, Caco2 cell monolayer model, active transport, HPLC, mediated
