Two species of oak are dominant in French forests: pedunculate oak (Quercus robur L.) and sessile oak (Quercus petraea Liebl.). Differentiating oak species is difficult, since features such as morphological characters, geographical origin and grain are not always relevant. Even if the former is generally richer in tannin compounds while the latter is often richer in aromatic compounds, the intra-species variability is high. The characterisation of the oak species remains a suitable indicator of the molecular composition and quality of the wood.

基于非靶向 UHPLC-Q-TOF-HRMS 测定橡树种 Quercus robur L. 和 Quercus petraea Liebl 的鉴别化合物。鉴别

两种橡木在法国森林中占主导地位：有花序橡木 ( Quercus robur L.) 和无梗橡木 ( Quercus petraea Liebl.)。区分橡树树种很困难，因为形态特征、地理起源和谷物等特征并不总是相关的。即使前者通常富含单宁化合物而后者通常富含芳香化合物，但种内变异性也很高。橡木树种的特征仍然是木材分子组成和质量的合适指标。
