The Structural nature of Tctracctron sinense MWL is characterized by means of Chemical analysis. GC, IR, ’H NMR and13C NMR spectra. The researches indicated that the MWL is of guaiacyl-syringyl type. The main connective form between structural units is β-O-4 aryl ether bonds. The quantity of β-O-4 and 5-5 substructures is 0.53 / C9 and 0.06 / C9, respectively. The aliphatic and phenolic hydroxyl contents are 1.11/C9and 0.30/C9, respectively. The OCH3 content is estimated by13C NMR is spectrum (1.14 / C9), which is consistent with chemical method (1.11 / C9), The degree of condensetion of the MWL is 0.51 / C9 (from HNMR), which is consistent with the result from13C NMR.
