氨茶碱[C_2H_8N_2(C_7H_8N_4O_2)_2·2H_2O]为茶碱与乙二胺的复盐。中国药典1985年版中氨茶碱片溶出度测定采用紫外分光光度法,而无水茶碱的含量测定采用银量法。我们曾试验用测溶出度的方法进行氨茶碱片中无水茶碱的含量测定,发现结果总是偏高。经分析无水茶碱与乙二胺的紫外光谱,发现系乙二胺在最
Aminophylline [C_2H_8N_2 (C_7H_8N_4O_2) _2 · 2H_2O] is a double salt of theophylline and ethylenediamine. Chinese Pharmacopoeia 1985 edition of aminophylline tablets dissolution assay using UV spectrophotometry, and anhydrous theophylline content measured by the amount of silver method. We have tested the method of dissolution test for determination of anhydrous theophylline aminophylline tablets and found that the results are always high. After analysis of anhydrous theophylline and ethylenediamine UV spectrum, Department of ethylenediamine found in the most
