Outline of Final Research Achievements

Lignin is a potencial alternative of aromatic resource. However, depolymerization process is neccessary to utilize lignin as a practical resource, subsequently analytical methods for the process need to be developed.
In this study, a comprehensive analytical method for depolymerized lignin was developed using liquid chromatography and high-resolution mass spectrometry. Applying tecniques in metabolomics, a method to classify behaviors of depolymerized lignins during alkaline cooking process was demonstrated. In addition, computational data of diverse theoretical chemical formulae of lignin oligomers were generated for structural elucidation of depolymerized lignins.
