Effect of three volatile oils on percutaneous penetration of aconitine through mouse skin in vitro / 中华中医药杂志

ABSTRACT

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.
