摘要:芦丁是一种来源很广的黄酮醇苷化合物,存在于槐树中,尤以槐米、果实中含量最为丰富。芦丁具有抗菌、抗炎、镇痛、抗病毒、抗过敏、抗氧化、降低毛细管通透性和抑制醛糖还原酶等多方面的药理活性。临床用于防治脑出血、高血压、视网膜出血、紫癜和急性出血性肾炎。本实验的目的是通过运用高效液相色谱技术,研究口服芦丁后小鼠肝脏器官内药代动力学变化规律。本实验是先运用高效液相色谱法测定不同浓度芦丁标准品的峰值,在通过将芦丁标准品溶液放入离体小鼠肝脏中模拟芦丁代谢实验,最后使小鼠口服芦丁标准品溶液,检测不同时间段小鼠肝脏内芦丁的药代动力学变化规律,研究其药代动力学参数,比较离体实验和体内实验的异同,为今后芦丁在临床用药方面提供参考。69054

Drug distribution studies in mice liver after oral administration of rutin
Abstract:Rutin is a kind of source is very wide flavonol glycosides compounds, exists in the locust trees, especially in the fruit of sophora japonica, the most abundant in content. Rutin has antibacterial, anti-inflammatory, analgesia, antivirus, allergy, oxidation resistance, reduce capillary permeability and pharmacological inhibition of aldose reductase activity. Clinical used in the prevention and treatment of cerebral hemorrhage, hypertension, retinal hemorrhage, purpura, and acute hemorrhagic nephritis. The purpose of this experiment is by using high performance liquid chromatography (HPLC) technique, research within liver organs in mice after oral rutin pharmacokinetic change rule. This experiment is to first use of high performance liquid chromatography determination of different concentration rutin standard peak, through the rutin standard solution in vitro experiment simulation of rutin in mice liver metabolism, and finally make oral rutin standard solution in mice, testing different times the pharmacokinetic change rule of rutin in the liver of mice, study its pharmacokinetic parameters, compare similarities and differences of in vivo and in vitro experiments, for the future rutin provide references of clinical medication.

前言
芦丁,又名芸香甙、维生素 P[1]、紫槲皮甙 、路丁、路丁粉、路通、络通、紫皮甙等,为浅黄色针状结晶(水),味微苦,熔点为177-178 ℃,略溶于水,能溶于热水及乙醇[2-3],遇光易变质,需在阴凉处保存,是一种来源很广的黄酮类化合物。芦丁来源于芸香叶、冬青科毛冬青、木樨科连翘、豆科槐角以及烟草叶、枣、杏、橙皮、番茄等植物中[4]。芦丁是豆科植物槐的花蕾(槐米)果实、金丝桃科植物红旱莲全草,芸香科植物芸香全草挥发油及蓼科植物荞麦籽苗中的主要充分。芦丁是一种维生素类药物,具有很多药理作用,如毛细血管的通透性降低时,芦丁可以增强毛细血管的脆性,使毛细血管恢复到正常,芦丁在临床医学上主要用于抗炎、抗病毒、防治高血压、脑溢血、糖尿病、视网膜出血、紫癜、抗老化和防辐射等,其治疗慢性支气管炎总有效率为84.4%,治脑血管病有效率为87.8%以及治视网膜水肿和出血有效率为88% 。文献综述 口服芦丁后小鼠肝内的药物分布研究:http://www.751com.cn/yixue/lunwen_77795.html
