Abstract
Lignin from Aralia cordata, was isolated and characterized spectrometrically and by chemical degradations. IR and 13C NMR spectra of the dioxan lignin showed a pattern of guaiacyl (G)-syringyl (S) lignin esterified with p-hydroxybenzoate. Alkaline hydrolysis of the lignin gave p-hydroxybenzoic acid. Molar ratios of the main syringyl to guaiacyl monomers recovered from alkaline nitrobenzene oxidation and from thioacidolysis are 1.3 and 1.2, respectively, indicating that A. cordata contains a guaiacyl-syringyl lignin, although the amount of syringyl lignin is a little lower than that in normal angiosperm wood.
