摘要
本研究对水青树(Tetracentron Sinense Oliv.)木材的各化学组分及全糖进行了全面的分析,测定了其磨木木质素的组成和官能团含量,并对其进行了结构分析。从而推得水青树木材磨木木质素的化学经验式为:C_9H_(7.76)O_(3.04)[(酚羟基的氧)_(0.26)(醇羟基的氧)_(0.85)(羰基的氧)_(0.11)(苯基烃基醚的氧)_(0.85)(二烃基醚的氧)_(0.93)(羧基的氧)_(0.04)](OCH_3)_(1.11);实验结果证明,水青树木材的各化学组分交错于针阔叶材之间,尤其是木质素的含量和组成都具有典型针叶材的特征。
In this paper, the chemical composition and the total sugar content of Tetracentron sinense Oliv. are analyzed, the chemical composition and function groups, of the Mill Wood Lignin (MWL) are determined, and then, the structure of the MWL is discussed. Therefore, the chemical formula of the MWL of Tetracentron sinense is defined as C_9H_(7.76)O_(3.04) (OCH_3)_(1.11).The results show that the chemical components of Tetracentron sinense interlace between broadleaf tree and conifer species. Especially, the composition and content of lignin show obvious characteristic of typical conifer species.
