Abstract:
Objective:To study the transdermal absorption in vitro of sinapine thiocyanate,tetrahydropalmatine and asarinin in Xiaochuan ointment so as to offer reference for its clinical application.Methods:A Franz diffusion cells method with isolated rat skins was carried out to study the percutaneous rate of sinapine thiocyanate,tetrahydropalmatine and asarinin determined by LC-MS/MS.Results:With the increase of administration dosage,the cumulative penetration of sinapine thiocyanate,tetrahydropalmatine and asarinin showed few changes.The results showed that the transdermal behavior of sinapine thiocyanate fit to a Higuchi equation,and that of tetrahydropalmatine and asarinin fit zero-order process.The penetration rate of tetrahydropalmatine and asarinin respectively was 0.362×10-1 and 0.330×10-2 μg·cm-2·h-1.Conclusion:Xiaochuan ointment exhibits transdermal penetration and absorption properties,which provides evidence for its transdermal administration.
