用中国药典方法鉴别眠尔通时,当药品量少则难以进行,而且操作繁琐。笔者通过实验采用颜色反应进行鉴别,取得良好效果,现报告如下。1.试剂:(1)浓硫酸(AR)(2)邻苯二甲醛试液:取邻苯二甲醛(benzol-1,2-dialdehyde)0.25g,溶于5ml无水乙醇中即得。2.鉴别:取眠尔通片剂(含眠尔通约0.05g)研细,加无水乙醇2ml 溶解,取滤液10滴于水 When using the Chinese Pharmacopoeia to identify Mellon, when the amount of the drug is small, it is difficult to carry out, and the operation is cumbersome. The author through experiments using color reaction identification, achieved good results, are as follows. 1. Reagents: (1) concentrated sulfuric acid (AR) (2) o-phthalaldehyde test solution: Take phthaldehyde (benzol-1,2-dialdehyde) 0.25g, dissolved in 5ml of absolute ethanol that was. 2. Identification: take Mirectone tablets (including Mild about 0.05g) research fine, add anhydrous ethanol 2ml dissolved, take the filtrate 10 drops of water
