磺胺类药物的系統鑑別法在药学刊物和書籍上已介紹过很多,归納起来,常見的可分成三类:(1) 磺胺药物經一定方法处理后在显微鏡下观察結晶形狀;(2) 磺胺药物处理成溶液后,加入試液,使溶液呈現一定顏色或产生沉淀、渾濁或放出气体;(3) 將磺胺药物加热,使呈显一定顏色和放出气体。在以上三类方法所包括的許多方法中:多数方法不够明显或不易辨別;有个別方法較好者,但需要有一定的設备和技术条件。为此,作者曾試用几种普通試剂鑑別常用的七种磺胺类药物,結果較为滿意。現將方法介紹如下。
Systematic identification of sulfa drugs in pharmaceutical journals and books have been introduced a lot, summed up, the common can be divided into three categories: (1) sulfa drugs after treatment by a certain method to observe the crystalline shape under the microscope; (2 ) Sulfa drug treatment into solution, adding test solution, the solution showed a certain color or precipitation, turbid or emit gas; (3) the sulfa drug heating, so as to show a certain color and emit gas. Among the many methods covered by the above three methods, most methods are not obvious or easy to discern. Individual methods are better but require certain equipment and technical conditions. To this end, the author has tried several common reagents to identify commonly used seven sulfonamides, the results are more satisfactory. Now the method described below.
