AbstractThe limited availability of adequate analytical methodologies for investigating complex biopolymers represents an important drawback for the study of lignin structure. The use of complementary spectroscopic and degradative analyses constitutes an adequate approach to monitorize chemical changes produced during pulping processes. The cereal straws represent an alternative raw-material for the production of certain types of paper pulps. However, structural informations concerning the complex lignins produced by grasses, which included p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units, and linked cinnamic acids, are relatively scarce.
