用毛细管气相色谱法对日本柳杉木材边材炭化得到的木醋液中的37种成分进行定性和定量分析.结果表明,醇类、酮类、羧酸类、呋喃类、苯酚类及愈创苯酚类是其主要成分.用溶剂萃取-硅胶柱层析法进一步分离处理木醋液,纯化出炭化过程中产生的手性脱水内醚糖-左旋葡聚糖(LGA,1,6-脱水-β-D-葡萄糖),但其不能被毛细管气相色谱法检测出.从150 mL木醋液中可分离纯化出60.5 mg LGA.另外,对木醋液中主要成分的生成路线也进行了分析和讨论.

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.
