摘　　要：目的　采用同位素示踪技术探讨不同促渗方法对丹芪益心贴中丹参酮ⅡA的经皮渗透速率的影响。方法　以3 H标记丹参酮ⅡA为指标 ,根据丹参酮ⅡA粪便排泄分数测定贴膏中丹参酮ⅡA的在体小鼠的透皮速率。结果　促渗剂能显著提高贴膏中丹参酮ⅡA经皮渗透速率 ;硝酸甘油预处理加促渗剂渗透速率明显高于单用促渗剂。结论　丹参酮ⅡA氚标记后用于透皮吸收实验研究是可行的 。Objective It is to discuss the influence of differen t enhancing osmosi s methods on TanshinoneⅡA percutaneous absorption rate in DANQIYIXINTIE through using radioisotope tracer technique.Methods Using 3H TanshinoneⅡA as the index, TanshinoneⅡA per cutaneous absorpti on rate in strapping of rat in vitro was tested based on TanshinoneⅡA stool exc retion fraction.Result Enhancing osmosis agent could significantly enhance Tanshin oneⅡA percuta neous absorbtion rate in strapping. The absorption rate of nitroglycerin pretrea tment plus enhancing osmosis agent was obviously higher than that of enhancing o smosis agent only.Conclusion It is a suitable method that TanshinoneⅡA marked by 3H is used in pe rcutaneous absorption empirical study. Enhancing osmosis agent plus low does of nitroglycerin pretreatment on skin can strengthen TanshinoneⅡA percutaneous abs orption rate.
