Each part of Sugi (Cryptomeria japonica D. Don), wood, inner bark, outer bark and leaf was carbonized at 400 ?C for 1h under nitrogen atmosphere. The material balance of carbonization products (charcoal, vinegar and tar) prepared from part of Sugi was determined, respectively. The vinegars from part of Sugi were all acidic solutions (pH=2.2~3.3). The constituents of vinegar and tar were determined by gas chromatograph-mass spectrometer (GC-MS). The vinegar from bark contained 46 compounds such as methanol, acetol, acetic acid, propanoic acid, 2-furaldehyde and pyrocatechol. The vinegar from leaf contained 44 compounds such as methanol, acetol, acetic acid, propanoic acid, pyrocatechol and hydroquinone. The tar from bark contained 63 compounds such as 4-hydroxy-4-methyl-2-pentanone, acetic acid, benzoic acid, pyrocatechol, m-cresol, 2,5-xylenol, guaiacol, (E)-isoeugenol and 1,6-anhydro-??-D-glucopyranose. The tar from leaf contained 63 compounds such as 4-hydroxy-4-methyl-2-pentanone, acetic acid, furfuryl alcohol, pyrocatechol, p-cresol, guaiacol, tridecane and 2-cyclopentenone.
