Abstract:目的:以丙烯酸酯和热熔胶为基质制备止痛活血(延胡索、川乌、白芍、三七等)压敏胶贴片来考察不同压敏胶基质对中药有效成分体外释放率的影响.方法:采用Permcell扩散池进行体外释放实验,用HPLC测定不同类型基质对止痛活血类中药中延胡索乙索、乌头碱、芍药苷、人参皂苷Rg_1等4种有效成分在接收液中累积浓度变化.结果:丙烯酸酯压敏胶(含羧基官能团)对生物碱类成分释放的影响较大,KT-A型热熔胶中有效成分释放速率与分子量呈一定相关性,2501 s型热熔胶贴片中4种成分的12 h累积释放率比较均衡(30%-43%).结论:有效成分的分子量越小释放速率越快,压敏胶的类型和组成明显影响中药有效成分的体外释放行为.
