New Preparations of Lignin Polymer Models under Conditions that Approximate Cell Wall Lignification

Abstract

Summary Lignin polymer model Guaiacyl-type lignin polymer models were prepared from coniferin by the action of s-glucosidase and Dehydrogenation polymer peroxidase, with hydrogen peroxide generated in situ through the action of oxygen and glucose oxidase of monolignols (DHP) Coniferin on the glucose liberated from the coniferin, Polylignols were also prepared from coniferyl alcohol using Monolignols glucoside procedures modified to more closely correspond to conditions prevailing in the cell wall environment. The structure of these novel polylignols approximated that of native lignin more closely than did the Coniferyl alcohol 13 C NMR structure of polylignols prepared by the conventional method from coniferyl alcohol.
