Abstract
[GRAPHICS] Significant quantities of arylpropane 1,3-diols have been identified in lig nins isolated from a CAD deficient pine mutant; smaller amounts are also pr esent in lignins from normal pine. They arise from dihydroconiferyl alcohol via the action of peroxidases which are responsible for the radical genera tion steps of lignification. The structures in the complex lignin polymers are proven using 2D and 3D NMR of isolated lignin fractions.
