dc.description.abstractThe content, composition and structure of lignin in a Eucalyptus globulus clone were studied at different growth stages (1 month, 18 months, and 9 years). The lignin content in the eucalypt woods increase during growth and the changes in its composition and structure were studied “in situ” by Py-GC/MS and 2D-NMR of the whole wood. In addition, milled-wood lignins were isolated and analyzed by Py-GC/MS, 2D-NMR and thioacidolysis followed by Raney Nickel desulfurization. The data obtained indicated that H and G lignin units are deposited first at the earlier stages, whereas the woods are enriched in S lignin during late lignification. The main linkages present were β-O-4' alkyl-aryl ether and resinol β-β', whereas other substructures (such as β-5' phenylcoumaran and β-1' spirodienones) were present in lower abundances during all stages of lignification. The differences in monomer deposition affect the distribution of the different linkages during lignification.es_ES
