The carbohydrate profile of some woods used for aging wines and spirits has been recently studied using a pressurized liquid extraction method, the main differences found being related to cyclitol content. The aim of this study was to perform a detailed study of these compounds in woods of different Quercus species in order to identify two unknown compounds which appeared in the extracts and to verify whether the obtained profile was homogeneous for other Quercus species.
Besides the known monosaccharides and five cyclitols previously described, three deoxy-inositols (epi-, vibo- and scyllo-quercitol) were identified. The presence of these eight cyclitols was confirmed in all subgenera and species of Quercus analyzed, allowing a characteristic cyclitol profile.
Three deoxy-inositols (quercitols) have been identified in the carbohydrate profile of oak wood. All examined Quercus species displayed a common profile consisting of four inositols and four quercitols, which represent a good dataset for characterization of this genus.
最近使用加压液体萃取法研究了一些用于陈酿葡萄酒和烈酒的木材的碳水化合物特征,发现的主要差异与环己醇含量有关。本研究的目的是详细研究不同栎属树种的木材中的这些化合物,以鉴定出两种在提取物中出现的未知化合物,并验证获得的图谱是否对其他栎属树种具有同源性。
除了先前描述的已知单糖和五种环己醇外,还鉴定出了三种去氧肌醇(表-、肌-和鲨肌醇)。在分析的栎属的所有亚属和种中都证实了这八种环己醇的存在,从而形成了一个特征性的环己醇图谱。
在橡木的碳水化合物特征中鉴定出了三种去氧肌醇(栎醇)。所有检查的栎属物种都显示出一种共同的图谱,由四种肌醇和四种栎醇组成,这代表了对该属进行特征描述的良好数据集。
