报导了水杨醛脲素席夫碱──２－羟基苯甲醛缩二缩脲和２－异两基氧基苯甲醛缩脲的合成方法．利用元素分析、红外光谱、紫外光谱、氢核磁共振谱对所合成的化合物进行了表征．并对化合物进行了抑制超氧阴离子自由基的研究．
The synthesis of salicylaldehyde urea Schiff base ─ ─ 2-hydroxybenzaldehyde biuret and 2-heterobutyloxy benzaldehyde urea urea were reported. The synthesized compounds were characterized by elemental analysis, IR, UV and 1H NMR spectra. The compounds were also investigated for their inhibition of superoxide anion free radicals.
