摘要

目的:研究丹黄凝胶体外释药特性和体外经皮渗透性。方法:采用改良Franz扩散池

以大黄酚、小檗碱为评价指标

运用动力学模型描述指标成分在体外的释药规律和经皮渗透规律。结果:大黄酚以零级动力释放模型拟合优度最好

小檗碱以Ritger-Peppas模型拟合优度最好;大黄酚和小檗碱在体外皮肤均以一级动力学渗透吸收;大黄酚、小檗碱体外释药特性与经皮渗透性的相关方程分别为Y=0.468 7X+4.972 2（r=0.966 4）

Y=0.666 9X+2.487 4（r=0.974 0）

体外释放速率均>体外经皮速率。结论:大黄酚、小檗碱体外释药特性与经皮渗透性存在较好线性相关性。

Abstract

Objective:To study on characteristics of in vitro release and transdermal penetration of Danhuang gel.Method:Modified Franz diffusion cell was used

with berberine and chrysophanol as indexes

in vitro drug release and percutaneous penetration laws of index components were described by kinetic model.Result:Release of chrysophanol could be fitted best by zero-power kinetics model

but berberine by Ritger-Peppas model;Penetration of chrysophanol and berberine in vitro skin were best by fitting for one-power kinetics model;Relevant linear equation of in vitro release and transdermal penetration for chrysophanol could be described as Y=0.468 7X+4.972 2（r=0.966 4）

berberine as Y=0.666 9X+2.487 4（r=0.974 0）

and in vitro release rate was higher than in vitro transdermal rate of two index components in Danhuang gel.Conclusion:In vitro release and transdermal penetration of berberine and chrysophanol had a good linear correlation.
