通过红外光谱和核磁共振氢谱分析了三种不同来源木质素的结构,发现针叶材木质素中含有大量的愈创木基丙烷结构,而没有紫丁香基丙烷结构的存在;阔叶材木质素和草本木质素中既有愈创木基丙烷结构也有紫丁香基丙烷结构。
Abstract：The structure of lignins from three different sourses was analyzed by IR and 1H-NMR,the result showed that abundant guaiacylpropane units and no syringylpropane units were found in the lignin structure of pine,besides both guaiacylpropane and syringylpropane units were found in the lignin structure of cornstalk and birch,which could explain the different effects in molecular level.
