Abstract: Pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) was used to analyze the pyrolysis product of Eucalyptus urophydis bark and its benzene-ethanol extractives. The main and abundant constituents of 590℃ pyrolysis product of E.urophydis bark were acetic acid (17.66%), 1,6-anhydro-β-D-glucopyranose (16.53%), carbon dioxide (15.75%), butane (10.22%), 1-hydroxy-2-propanone (10.19%), 1-propanol (9.73%), etc. The main and abundant constituents of pyrolysis product of benzene-ethanol extractives of E. urophydis bark were 9,12-octadecadienoic acid (Z,Z)- (7.14%), n-hexadecanoic acid (6.89%), 8-propoxy-cedrane(6.65%), 4-hydroxy-3,5-dimethoxy-benzaldehyde(5.81%), 2,6-dimethoxy-phenol(5.79%), ergosta-4,6,22-trien-3α-ol (5.68%), 2-methoxy-4-vinylphenol (5.03%), 2-methoxy-4-(1-propenyl)-phenol, (4.90%), carbon dioxide (4.32%), stigmastan-3,5-diene (3.35%), 2,3,5,6-tetrafluoroanisole (3.13%), 2-methoxy-phenol(3.09%), etc.
