Abstract
The chemical characteristics of lignin in the differentiating xylem were investigated and compared with those of mature-wood. The compound middle lamella lignin deposited in the early stage of lignification of cell walls in the softwood(Larch) as well as the hardwood(Birch) was confirmed to be the so-called guaiacyl-type lignin and was found to have a relatively larger content of phenoxy hydroxyl group as terminal units and to be more abundant in condensed-type structures like as phenylcoumaran structures compared with mature-wood lingin.
세포간층 lignin은 2차벽 lignin(end-wise-polymer)에 비해 축합도가 높으며 guaiacyl type의 phenol성 수산기등 말단기를 많이 갖는 2차벽 lignin보다 저분자량의 bulk polymer형 lignin이다.
