Aromatic aldehydes (vanillin, syringaldehyde, coniferaldehyde and sinapaldehyde) and coumarins (esculetin, umbelliferone, scopoletin and methylumbelliferone) are natural wood compounds. Storage of wines and brandies in oak barrels increases notably aldehydes and coumarins (particularly scopoletin) concentrations. These compounds were separated by high-performance liquid chromatography, on hydrocarbon bonded reversed-phase packings, with a water-acetonitrile elution gradient. They were first extracted from wines and brandies by diethyl ether and then injected on chromatographic column. A double detection was used to determine simultaneously aromatic aldehydes and coumarins by UV absorption and fluorescence respectively.
芳香醛（香草醛、丁香醛、松柏醛和芥子醛）和香豆素（七叶亭、伞形酮、东莨菪素和甲基伞形酮）是天然的木质化合物。葡萄酒和白兰地在橡木桶中储存会显著增加醛类和香豆素（尤其是东莨菪素）的浓度。这些化合物通过高效液相色谱法，在烃基键合反相填料上，采用水 - 乙腈洗脱梯度进行分离。它们首先用乙醚从葡萄酒和白兰地中萃取出来，然后注入色谱柱。采用双重检测分别通过紫外吸收和荧光同时测定芳香醛和香豆素。
