摘要：

The amount of the diarylpropane type structure in spruce lignin was determined by the use of an ozonation method. Ozonation of both the diarylpropane and the phenylcoumaran type structures resulted in the formation of a dicarboxylic acid which possesses the original configurative structure of the side-chain. By determining yields and ratios of erythro and threo isomers of this dicarboxylic acid formed from model compounds and MWL, it was elucidated that the diarylpropane type structure can not be one of the major structures in spruce lignin. © 1990, Walter de Gruyter.
