The photo-stability and the structures of photo-oxidation products of aminophylline in aqueous solutions were investigated. When an aqueous solution of aminophylline was submitted to photo-oxidation in the presence of oxygen under daylight, aminophylline was decomposed to yield 1, 3-dimethylallantoin, N, N'-dimethyloxamide and ammonia as main products. It was found that photodegradation of theophylline in an aqueous aminophylline solution was closely related to that of ethylenediamine in the same solution.
