Structural characterization of lignin in heartwood, sapwood, and bark of eucalyptus.

Abstract：

:Understanding the distribution and structural features of lignin in heartwood, sapwood, and bark of terrestrial plants is important to optimize the industrial utilization of lignocellulose. In this work, the lignins in heartwood, sapwood, and bark of Eucalyptus urophylla × E. grandis were comparatively studied. Confocal Raman microscopy was used to probe the heterogeneity of lignin distribution in situ. The swollen residual enzyme lignin samples were isolated and systematically characterized to determine the structural differences. The results showed that the content and molecular weights of lignin gradually decreased in the order of heartwood, sapwood, and bark. The S/G ratios of heartwood lignin (3.45) and sapwood lignin (2.74) suggested the increase of deposited S-type lignin with the maturity of wood. The bark lignin exhibited a high frequency of β-O-4' linkages and showed a unique substructural pattern with the absence of spirodienone substructures and p-hydroxycinnamyl alcohol end-groups.
