中文摘要：

【目的】研究环维黄杨星D醇质体的体外经皮渗透特性。【方法】分别制备环维黄杨星D醇质体、普通脂质体、过饱和水溶液及35.5%（质量分数）乙醇溶液,采用体外经皮渗透法比较各制剂的体外经皮渗透性。【结果】醇质体可明显提高药物的稳态透皮速率,其增渗比为8.85,促渗效果优于普通脂质体和35.5%乙醇溶液。12 h皮肤中药物滞留量的顺序依次为35.5%乙醇溶液〉普通脂质体〉醇质体。【结论】与普通脂质体比较,醇质体可明显提高环维黄杨星D稳态透皮速率,有利于药物发挥全身作用。

英文摘要：

Objective To investigate the in-vitro transdermal permeability of cyclovirobuxine D ethosomes.Methods Ethosomes,liposomes,saturated aqueous solution and 35.5% saturated alcohol solution of cyclovirobuxine D were prepared.The in-vitro transdermal permeability of different kinds of preparations of cyclovirobuxine D was studied by in-vitro permeation experiments.Results Cyclovirobuxine D ethosomes enhanced transdermal flux rate of cyclovirobuxine D and the enhancement ratio was 8.85,superior to liposomes and saturate alcohol.The dermatic hold-up amount of cyclovirobuxine D in 35.5% saturated alcohol solution,liposomes and ethosomes was in a decreasing sequence.Conclusion Compared with the liposomes,the ethosomes can enhance the transdermal flux rate of cyclovirobuxine D,which could increase the systematic action of the drug.
