Incorporation of [2-13C]ferulic acid, a lignin precursor, into Leucaena leucocephala and its analysis by solid state 13C n.m.r. spectroscopy

Abstract

Solid state ¹³C n.m.r. analysis of lignin in situ, in the root tissue of the woody angiosperm, Leucaena leucocephala, and specifically labelled at a carbon site thought to be involved in the majority of inter-unit linkages, revealed significant bonding differences when compared to an artificial lignin preparation generally viewed more or less to represent native lignin structure.
