RESUMO
Objective To investigate the effects of volatile oils of Rhizoma Acori Tatarinowii (RAT), Semen Myristicae (SM) and Pericarpium Citri Reticulatae (PCR) on percutaneous penetration of total alkali of Shortstalk Monkshood Root through mouse skin in vitro. Methods By using an improved Franz diffusion cells, the effects of these 3 kinds of volatile oil on the percutaneous penetration of total alkali of Shortstalk Monkshood Root were observed and compared with Azone, and the cumulative amount of Bullatine A was determined by HPLC. Results 7% (v/v) volatile oil RTA and SM, 5% (v/v) volatile oil of PCR and 3% (v/v) Azone were best concentration, the penetration coefficient were 5.88, 6.91, 5.30, 5.75, respectively. Compared with the group without penetration enhencers, the enhancement ratios were 1.09,1.28, 0.98, 1.06, respectively. Conclusion The volatile oil of RAT and SM enhance penetration of total alkali of Shortstalk Monkshood Root. The volatile oil of PCR cannot enhance penetration.
RESUMO
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.
