| Abstract: | Thirty-seven components in wood-vinegar obtained from the carbonization of sugi sapwood were determined by capillary gas chromatography (GC). The results showed that main components in sugi wood-vinegar were methanol,ketones, carboxylic acids, furans, phenols and guaiacols. The methods of solvent extraction and silica gel column chromatography were used to further investigate the unknown components in the wood-vinegar. The chiral levoglucosan ( LGA, 1,6-anhydroβ-D-glucose) as an unknown component was isolated from sugi wood-vinegar,which was not able to bo detected by the capillary GC. 60.5 g LGA can be separated from 150 mL sugi wood-vinegar. The pathway of the formation of major components in sugi wood-vinegar was also analyzed and discussed. |
