摘要: 通过液液萃取-气相色谱-质谱联用法以法国产橡木(Quercus acutissima Caruth)为对照,对原产于我国的辽东栎(Quercus liaotungensis Koidz)和蒙古栎(Quercus mongolica Fisch)2 种橡木树种心材的挥发性成分进行分析,鉴定出呋喃、挥发性酚、酚醛、内酯和其他5 类组分,其中,国产辽东栎心材的挥发性成分在种类和含量上最高(88 种、75 113.03 μg/kg),法国橡木次之(79 种、70 940.18 μg/kg),国产蒙古栎心材最低(77 种、52 967.62 μg/kg)。主成分分析和热图分析结果表明,辽东栎在愈创木酚及其衍生物、香草醛和丁香醛等成分上具有较高相关性,具有明显的花香、果香特征,表现出较好的应用潜力,因此可能作为传统橡木的替代资源。

Abstract: This study aimed to investigate the volatile components of the heartwood of Quercus liaotungensis Koidz and Q. mongolica Fisch, both originating in China, by liquid-liquid extraction combined with gas chromatography-mass spectrometry (LLE-GC-MS). Five kinds of components, including furans, volatile phenol, phenolics, lactones and others, were preliminarily identified. Q. liaotungensis Koidz contained the largest number and amount (88 and 75 113.03 μg/kg) of volatile components, followed by Q. acutissima Caruth produced in France (79 and 70 940.18 μg/kg), and the number and amount of volatile components in Q. mongolica Fisch (77 and 52 967.62 μg/kg) were the smallest. Furthermore, principal component analysis (PCA) and heat map analysis showed that the Q. liaotungensis Koidz exhibited a high correlation between guaiacol and its derivatives, vanillin and syringaldehyde, and obvious flowery and fruity aroma characteristics, showing good application potential. Thus, it may be an alternative to traditional oak.

Key words: Quercus liaotungensis Koidz; Quercus mongolica Fisch; furans; phenolics; lactones
