C. Gomezcordoves et al., IDENTIFICATION OF 2,3-DIHYDROXY-1-GUAIACYLPROPAN-1-ONE IN BRANDIES, Journal of agricultural and food chemistry, 45(3), 1997, pp. 873-876
We have purified and identified a new phenolic compound in brandies ag
ed in wood. Spectral structural analysis by HPLC-DAD suggested that th
e 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. Conce
ntration of this ketone in brandies is related to the genuine aging of
these beverages in oak and, therefore, to their market value.
