Abstract

The effect of alkali extraction on the lignin monomeric composition was examined in Eucalyptus camaldulensis and E. globulus by thioacidolysis using extractive-free samples as a control. Results showed that the effect on Eucalyptus is different among species and among sample positions in the trunk, although a small amount of lignin is solubilized during the extraction in all samples. In addition, it was proved that lignin extracted by the alkali extraction is not always guaiacyl-rich, probably relating to the original lignin monomeric composition, which depends on the sample species or the sample position in the trunk.
