摘要：
We have purified and identified a new phenolic compound in brandies aged in wood. Spectral structural analysis by HPLC-DAD suggested that the unknown compound corresponded to a 3-methoxy-4-hydroxybenzoic ketone with an aliphatic chain containing hydroxyl groups. H-1 NMR analysis confirmed its structure as 2,3-dihydroxy-1-guaiacylpropan-1-one. Concentration of this ketone in brandies is related to the genuine aging of these beverages in oak and, therefore, to their market value.
