"In situ" analysis of lignin by 2D-NMR of wood (Eucalyptus globulus and Picea abies) and non-woody (Agave sisalana) plant materials at the gel state
"In situ" analysis of lignin by 2D-NMR of whole lignocellulosic materials was carried out by swelling in dimethylsulfoxide (DMSO-d6) finely ground samples, and forming a gel in the NMR analysis tube. Solution HSQC-NMR spectra of lignocellulosic materials representative for hardwood (Eucalyptus globulus), softwood (Picea abies) and non-woody plants (Agave sisalana) at the gel state are presented showing signal corresponding to the main plant constituents. The obtained spectra showed both lignin and carbohydrates signals and the assignment of the lignin signals was obtained by comparing the lignocellulose spectra with spectra of MWL isolated from the same materials.
