NEW PREPARATIONS OF LIGNIN POLYMER MODELS UNDER CONDITIONS THAT APPROXIMATE CELL-WALL LIGNIFICATION .1. SYNTHESIS OF NOVEL LIGNIN POLYMER MODELS AND THEIR STRUCTURAL CHARACTERIZATION BY C-13 NMR

Guaiacyl-type lignin polymer models were prepared from coniferin by th e action of beta-glucosidase and peroxidase, with hydrogen peroxide ge nerated in situ through the action of oxygen and glucose oxidase on th e glucose liberated from the coniferin. Polylignols were also prepared from coniferyl alcohol using procedures modified to more closely corr espond to conditions prevailing in the cell wall environment. The stru cture of these novel polylignols approximated that of native lignin mo re closely than did the structure of polylignols prepared by the conve ntional method from coniferyl alcohol.
