In this study, Derivatization Followed by Reductive Cleavage (DFRC) method is used to investigate the structures of milled wood and dioxane lignin of Populus nigra. After carrying out DFRC reactions, the structures of constituents resulted from these two kinds of lignin were investigated by using several spectral methods such as NMR, GC-MASS and GPC. The results obtained from chromatography and spectroscopy studies of these methods have been compared. These comparative results show that the dominant structural components of these two kinds of lignin are obtained from cleavage of ?-O-4 bonds. The main components obtained from dioxane lignin and milled wood lignin are 4-hydroxy-3,5-dimethoxy-1-phenyl propene and 4-hydroxy-3,5-dimethoxy-1-phenyl-?-hydroxy propene (syringyl structures), respectively. Also, there are some guaiacyl structures in these components.
