摘要: 目的:基于大鼠离体外翻肠囊模型探讨豆腐果苷在不同肠段的吸收情况。方法:建立豆腐果苷及其代谢产物高效液相色谱同时检测方法。在不同肠段(十二指肠、空肠、回肠、结肠)的外翻肠囊模型中加入含豆腐果苷的Krebs-Ringer液,不同时间点(5,10,15,30,45,60,75,90 min)取样并测定囊内药物浓度,比较四个肠段对豆腐果苷的吸收情况。结果:所建立的高效液相色谱法成功应用于豆腐果苷及其代谢产物同时检测。豆腐果苷及其代谢产物吸收迅速并呈明显的时间依赖性,十二指肠段的吸收与代谢情况均高于其他肠段。结论:十二指肠肠段是豆腐果苷分肠段吸收与代谢的主要部位,这是豆腐果苷肠段代谢研究的首次报道。

Abstract: AIM: To investigate the absorption of helicid in different segments of intestine based on rat everted intestine sac model.  METHODS: To establish a high-performance liquid chromatography method for simultaneous determination of helicid and its metabolite. Krebs-ringer solution containing helicid was added to everted intestine sacs of different segments (duodenum, Jejunum, ileum and colon). Drug concentration in sacs was determined at different time points (5, 10, 15, 30, 45, 60, 75, 90 min). Adsorptions of helicid in four intestinal segments were compared. RESULTS: This high-performance liquid chromatography was successfully applied to the simultaneous determination of helicid and its metabolite. Absorption of helicid was rapid and time-dependent. The absorption and metabolism of helicid in duodenum segment were higher than these in other segments. CONCLUSION: The duodenum segment is the main site of segmental absorption and metabolism of helicid. This is the first report on intestinal segment metabolism of helicid.

Key words: helicid, everted intestinal sac model, absorption, metabolism
