摘要 采用气相色谱-质谱(GC-MS)联用技术分析了不同烟温度采集的柞木木醋液的有机成分.结果表明,柞木木醋液是一种组成成分相当复杂的混合物,在不同温度下采集的木醋液,其主要有机成分分别为:低温(烟温度80~90℃)是醇类;中温(烟温度90~150℃)是醇类、酮类和有机酸类;高温(150℃以上)是酮类、有机酸类(主要是乙酸)、醇类和酚类.从木醋液有效成分(以有机酸含量为标准)上看,90℃开始收集可以获得较多的有效化学成分.3种不同烟温度采集的柞木木醋液,其有机酸含量、pH值和精制得率也不同. The organic components of wood vinegar for Mongolian oak collected at different temperatures were analyzed with Gas Chromatograph-Mass Spectrometer (GC-MS). The results indicated that Mongolian oak wood vinegar was a kind of quite complicated compounds. The organic components changed with smoke temperature: from 80 ℃ to 90 ℃ were mainly alcoholic compounds, from 90 ℃ to 150 ℃ were mostly alcoholic compounds, ketonic components, organic acids and phenolic compounds, while above 150 ℃ were ketonic compounds, acetic acid, alcoholic compounds and phenolic compounds. The optimizing collection temperature was above 90 ℃ so that more organic acids could be obtained. In addition, the organic acid content, pH value and refined yields were various at different collecting temperatures.
