复方阿斯匹林片是药房医院中最常用的一种药,也是一般分析检验机构中,经常收到的化验样品之一。复方阿斯匹林片的分析方法,在中国药典上虽有规定,但因采用重量法,故手续上极为麻烦,时间药品浪费亦多。我们参考苏联药典的分析方法,经试验结果,认为此中国方法要优越得多,现在把苏联药典上的方法,以及我们试用后的几点经验与体会,简单的介绍于下。一、苏联药典(第八版)方法1)阿斯匹林的测定:取本品二片,与少量的中性醇置乳钵中研磨,再以等量的中性醇,将其移入锥形瓶中,并用少量中性醇洗涤乳钵,使其容积为25ml,加酚(?)试液为指示剂,以 N/(10)NaOH 标准液滴定
Compound aspirin tablets are the most commonly used drugs in pharmacy hospitals, and they are also one of the routinely received laboratory samples in general analytical testing institutions. Although the analytical method of compound aspirin tablets is stipulated in the Chinese Pharmacopoeia, due to the weight method, the procedures are extremely troublesome and the time waste of drugs is also large. We refer to the analytical methods of the Soviet Pharmacopoeia. After the test results, we believe that this Chinese method is much superior. Now we briefly introduce the methods of the Soviet Pharmacopoeia and some experiences and experiences after our trial. First, the Soviet Pharmacopoeia (eighth edition) Method 1) Determination of aspirin: Take two tablets of this product, grind it with a small amount of neutral alcohol in a mortar and place it in the same amount of neutral alcohol. In a vial, wash the chyle with a small amount of neutral alcohol to a volume of 25 ml and add a phenol (?) test solution as an indicator, set in standard droplets of N/(10) NaOH.
