Objective To study the effects of different penetration enhancers on the transdermal penetration of Miao medicine named Diploclisia affinis. Methods Improved Franz diffusion cell was adopted as the apparatus for in vitro mouse' skin permeation. The kinetic parameters of percutaneous absorption, such as penetration rate, enhancing rate (ER), and lag time (Tlag) were determined by high performance liquid chromatography. Azone, oleic acid (OA) and borneol were investigated for percutaneous absorption effects. Results The penetration rates of the medicine with 3% azone, OA and borneol added were respectively (214.1872±13.5690), (227.5544±9.8490), and (168.1187±21.5640) μg/(cm2·h), and the ER was 1.61, 1.71, and 1.26 compared with the penetration rate of that with nothing added. The Tlag was 2.1081, 1.8256, and 2.9655 hours. Conclusion All the penetration enhancers can increase significantly the absorption of Miao medicine named Diploclisia affinis, especially 3% OA is the best, but 3% borneol may make the Tlag longer.
