从抗稻瘟病水稻品种(oryzae cav.)叶片中分离得到两种天然的脲类衍生物:乙基-4-(邻硝基苯基)-3-硫代脲酸酯(1)和乙基-4-(邻硝基苯基)-3-脲酸酯。它们的波谱分析数据已经测定。生物活性研究表明化合物1具有特殊的生物活性。
Two natural derivatives of urea were isolated from the leaves of an oryzae cav. Blastocyst: ethyl-4- (o-nitrophenyl) -3-thioureaslate (1) and ethyl -4- (o-nitrophenyl) -3-urea. Their spectral analysis data have been determined. Biological activity studies show that Compound 1 has a special biological activity.
