The bamboo lignin is rich in syringyl units, which is indicated by a high methoxyl content and respective bands in the IR spectrum.
从甲氧基含量高以及红外光谱中各吸收峰可知在竹材木素中富含丁香基。
The results showed that the lignin in the unbleached pulp was mainly composed of syringyl lignin (S-lignin) and guaiacyl lignin (G-lignin).
结果表明未漂浆中主要存在紫丁香基木素和愈疮木基木素，漂白过程中缩合的愈疮木基木素溶出相对较少。
