透皮促进剂对天山雪莲巴布剂中3种有效成分经皮渗透的影响

目的:研究不同透皮促进剂对天山雪莲巴布剂中3种有效成分紫丁香苷、绿原酸及芦丁体外经皮渗透的影响,筛选有效的透皮吸收促进剂.方法:采用改良的Franz扩散池,以离体大鼠皮肤为透皮屏障,用高效液相色谱法测定透皮吸收促进剂对紫丁香苷、绿原酸及芦丁的透皮速率及累积透皮百分率等体外透皮吸收动力学参数的影响.对氮酮(azone)、丙二醇(PG)透皮吸收促进剂单独应用和合用的促渗效果进行考察.结果:7%氮酮为促进剂,天山雪莲巴布剂中紫丁香苷、绿原酸及芦丁3种有效成分的促透效果最好.结论:通过考察促进剂对天山雪莲巴布剂中紫丁香苷、绿原酸及芦丁的影响,为天山雪莲巴布剂的制备提供实验依据.

Effect of several penetration enhancers on transdermal absorption in vitro of syringin, chologenic acid and rutin in Xuelian cataplasm

Objective: To study the effects of different penetration enhancers on the transcutaneous permeability of of syringin, chologenic acid and rutin in Xuelian cataplasm in vitro and to determine the effective enhancer. Method: Using improved Franz type diffusion cell and excised big mouse skin in vitro as transdermal barrier, the kinetics parameters of syringin, chologenic acid and rutin in Xuelian cataplasm such as cumulative permeation quantity, permeation rate were determined by HPLC. The enhancement ability of azone (A zone), propylene glycol (PG) was investigated when used either uniquely or combinatively. Result: With the 7% azone, the syringin, chologenic acid and rutin in Xuelian cataplasm could penetrate through the skin of rats well. Conclusion: The selection of the best penetration enhancers provide reference for Xuelian cataplasm.
