Lignin - Wikipedia

Lignin is a class of complex organic polymers that form important structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily.Chemically, lignins are cross-linked phenolic polymers.

Chemistry and Properties of Woods - Carbolea

Stem wood in temperate-zone hardwoods contains 40-50% cellulose, 20-25% lignin, and 25-35% hemicelluloses. Wood Hemicelluloses While the cellulose content does not vary greatly in quantity and composition between normal hardwoods and softwoods, there are characteristic differences between the composition and structure of the hemicelluloses .
