荜澄茄等3种挥发油对乌头碱经皮渗透的影响

目的:研究荜澄茄、干姜、石菖蒲挥发油对乌头碱经皮渗透的影响。方法:采用改良Franz扩散池法,以HPLC法测定模型药物乌头碱的累积渗透量,考察不同浓度的荜澄茄、干姜、石菖蒲挥发油对乌头碱的促渗效果。结果:7%浓度的荜澄茄、干姜、石菖蒲挥发油与3%氮酮的渗透系数(×10-3cm/h)分别为:10.79、5.82、5.40、3.91,与无促渗剂的对照组比较,差异均具有显著性意义,促渗倍数分别为3.87、2.09、1.94、1.40倍,可见7%的3种挥发油促渗倍数均大于3%氮酮。结论:7%的荜澄茄、干姜、石菖蒲挥发油均能明显促进乌头碱的经皮渗透。

Effect of three volatile oils on percutaneous penetration of aconitine through mouse skin in vitro

Objective: To study the effect of volatile oil of Fructus Litseae(FL) ,Rhizoma Zingiberis(RZ) and Rhizoma Acori Talarinowii(RAT) on percutaneous penetration of aconitine through mouse skin in vitro.Methods :By using improved Franz diffusion cells,the effects of these 3 volatile oils on the percutaneous penetration of aconitine were observed and compared with azone,and the cumulative amount of aconitine was determined by HPLC.Results : The penetration coefficient of aconitine with 7%(v/v) volatile oil of FL,RZ and RAT and 3% azone were 10.79,5.82,5.40,3.91,respectively;Compared with the group without penetration enhancers,the differences were significannt;and the enhancement ratios were 3.87,2.09,1.94 and 1.40,respectively,which showed the enhancement ratios of 7% of the 3 volatile oils were higher than that of 3% azone.Conclusion :The 7% volatile oils of FL,RZ and RAT enhance the permeation of aconitine effectively.
