伤湿止痛热熔压敏贴膏质量标准研究
Chinese Journal of Experimental Traditional Medical Formulae(2012)
Abstract
目的:建立伤湿止痛热熔压敏贴膏的质量控制方法。方法:采用薄层色谱法对伤湿止痛热熔压敏贴膏中颠茄流浸膏进行定性鉴别;采用高效液相色谱法对贴膏中马钱子碱和士的宁进行含量测定。结果:在薄层色谱中能检出颠茄流浸膏中硫酸阿托品的特征斑点;高效液相色谱法测定贴膏中马钱子碱和士的宁的含量,士的宁在0.53~53.0 mg.L-1线性关系良好(r=0.999 5),其平均回收率为95.57%,RSD 2.91%(n=6);马钱子碱在0.50~50.0 mg.L-1线性关系良好(r=0.999 5),其平均回收率为97.95%,RSD 1.43%(n=6)。结论:方法简便、专属性强、重复性好,可用于控制伤湿止痛热熔压敏贴膏的质量。
