复方乙酰水杨酸片是一种常用的解热镇痛药,每片含乙酰水杨酸0.22g,非那西丁0.15g,咖啡因0.035g。卫生部药品标准对这3种成分采用化学反应方法进行鉴别,方法繁琐,费时,反应不明显。有报道用薄层色谱法同时鉴别去痛片中的4种成分,本实验采用薄层色谱法同时鉴别复方乙酰水杨酸片中的乙酸水杨酸、非那西丁和咖啡因3种成分,专一性强,斑点明显,操作简便,结果较为满意。
Compound acetylsalicylic acid tablets is a commonly used antipyretic analgesics, each containing acetylsalicylic acid 0.22g, phenacetin 0.15g, caffeine 0.035g. Ministry of Health drug standards for these three components using chemical reaction method identification, tedious method, time-consuming, the reaction was not obvious. There are reports using thin layer chromatography simultaneous identification of four components in painkillers, thin layer chromatography in this experiment simultaneous identification of compound acetylsalicylic acid tablets salicylic acid, phenacetin and caffeine three kinds of ingredients , Specificity, obvious spots, easy to operate, the result is more satisfied.
