桢楠阴沉木与现代木木材化学成分与表面颜色研究

研究桢楠阴沉木与现代木木材化学成分与表面颜色差异，为进一步研究桢楠阴沉木的形成机理提供理论依据。结果显示，阴沉木形成过程中，半纤维素的特征峰减小最为明显，表明在桢楠阴沉木形成过程中半纤维素发生降解的程度最大。与现代木相比较，桢楠阴沉木 L* 值下降了 24.83%，亮度偏暗，a* 值为-10.0，颜色偏绿，色差与色调差异明显。桢楠阴沉木的形成伴随着木材化学成分的变化。This study investigated the differences in chemical compositions and surface color between Phoebe zhennan buried wood and modern wood, aiming to provide a theoretical basis for further research on the formation mechanism of Phoebe zhennan buried wood. The results showed that the characteristic peaks of hemicellulose decreased most significantly during the formation of buried wood, indicating that hemicellulose underwent the highest degree of degradation during its formation. Compared with modern wood, the L* value of Phoebe zhennan buried wood decreased by 24.83%, resulting in lower lightness; its a* value was -10.0, exhibiting a greenish tint, with significant differences in both color difference and hue. The formation of Phoebe zhennan buried wood is accompanied by changes in wood chemical compositions.
