摘要
目的:研究委陵菜黄酮在SD大鼠小肠内的吸收行为。方法:应用缚管翻转肠囊法,考察委陵菜黄酮在高、中、低3个浓度下在大鼠小肠内的吸收行为。结果:在一定浓度范围内,随着委陵菜黄酮溶液浓度的升高,委陵菜黄酮在小肠内的转运量也增加,表明委陵菜黄酮的转运具有浓度依赖性。结论:委陵菜黄酮在大鼠小肠内的吸收过程符合一级消除动力学模型,符合被动转运的特征。
Objective: To study the absorption of potentilla flavone in isolated rat small intestine. Methods: Everted-gut technique was utilized to study the absorption properties of potentilla flavone at three different concentration range (high range, middle range and low range). Results: The absorption of potentilla flavone increased according to their concentration in a definite concentration range, as well as a eoncentration-depent. Conclution: The pharmacokinetics of gut absorption studies showes the absorption of potentilla flavone fits to linear absorption model and the passive transport features.
