| 摘 要： | 采用紫外光谱、红外光谱、核磁共振波谱、凝胶渗透色谱和有机元素分析对从马尾松正常木与应压木中提取的纤维素酶酶解木素的结构进行比较研究。结果表明:马尾松正常木与应压木木素的芳香环结构主要以愈创木基为主,有少量的对羟基苯基;都含有较多的脂肪族羟基;与正常木木素相比,应压木木素含有较多的对羟基苯基单元和酚羟基,其中缩合酚羟基和对羟基酚羟基较多,还含有少量的紫丁香基酚羟基;应压木木素中的甲氧基、羧基、β-O-4键、β-5键,β-β键和β-1键较少;正常木与应压木木素的经验式分别为C9H7.27O1.53(OH)0p.H19(OH)1A.118(OCH3)1.23和C9H7.28O1.54(OH)0p.H20(OH)1A.117(OCH3)1.13。 |

| Abstract: | The cellulolase lignin structures of normal and compression wood of Masson Pine ( Pinus massoniana) were studied comparatively by UV,FTIR,NMR,GPC and elemental analysis. The results showed that the aromatic skeletals of lignin in normal and compression wood mainly consisted by guaiacylpropane and some p-hydroxyphenylpropane units. They had a large number of aliphatic hydroxyl. Compared with the lignin of normal wood,the contents of p-hydroxyphenypropane units and phenolic hydroxyl groups were higher in the ... |
