不同精制法松树木醋液中生物活性组分的富集

采用GC-MS分析法研究了3种精制法所得木醋液对小兴安岭松树木醋液中主要生物活性组分羧酸和酚类的富集,包括物理静置法所得原松木醋液、蒸馏法所得松木醋液和膜过滤法所得松木醋液。结果表明,3种精制方法中,蒸馏法和膜过滤法都可以进一步去除原木醋液中的有色有害大分子,使颜色变浅。蒸馏法松木醋液有利于木醋液中乙酸等羧酸的富集;膜过滤法松木醋液有利于对苯酚和愈创木酚等酚类的富集,且对羧酸和酚类总的生物活性成分的富集较有优势。

Enrichment of Bioactive Components in Pine Wood Vinegar Based on Different Refining Methods

Enrichment of main bioactive components in three different xiaoxing'an mountains’ pine vinegar made by standing only, distillation and membrane filtration was analyzed by GC-MS. Research results showed that among the three kinds of refining methods, the latter two could remove colored harmful macromolecules so that the color became lighter. Distillation pine vinegar was more conducive to enriching organic acid and membrane filtration pine vinegar preferred to enrich phenol, guaiacol and even the total biological active component including acid and phenols.
