采用气相色谱-质谱联用（GC-MS）和气相色谱-嗅觉联用（GC-O）技术对美国、法国、匈牙利和俄罗斯栎木材浸提液中的香气活性成分进行了研究。化合物，提出高气味强度的非烤橡木愈创木酚，己醛，反式-2-壬烯醛，反式橡木内酯，顺式橡木内酯，丁香酚，香草醛和反式异丁香酚，而相同的化合物，除了糠醛，4-甲基愈创木酚和顺式异丁香酚，证明了重要的烤橡木。像橡木内酯一样，顺式和反式异丁香酚呈现木质/橡木气味，特别是在烘烤样品中。对于匈牙利和俄罗斯的样品，其特点是他们的橡木内酯，反式和顺式异丁香酚含量较低，提出了更高的气味强度。出于这个原因，低橡木内酯浓度的样品，如匈牙利和俄罗斯橡木，但也含有异丁香酚，可以赋予葡萄酒木质/橡木气味。版权所有（C）2008约翰威利父子有限公司
Gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O) were used to study aroma-active compounds in extracts of American, French, Hungarian and Russian oak woods. Compounds that presented high odour intensities for the non-toasted oak woods were guaiacol, hexanal, trans-2-nonenal, trans-oak lactone, cis-oak lactone, eugenol, vanillin and trans-isoeugenol, whilst the same compounds, in addition to furfural, 4-methylguaiacol and cis-isoeugenol, proved important in the toasted oaks. Like the oak lactones, cis- and trans-isoeugenol presented woody/oak odours, particularly in the toasted samples. For Hungarian and Russian samples, both characterized by their lower content of oak lactones, trans- and cis-isoeugenol presented higher odour intensities. For this reason, samples of low oak lactone concentrations, such as Hungarian and Russian oak woods, but also containing isoeugenols, can impart woody/oak odours to wines.
