Abstract
A series of polyphenols with a new skeleton, named castavinol, has been isolated from Bordeaux red wines. The structural elucidation of these three natural products was achieved by UV, MS, IR, NMR 1H and 13C spectroscopies. The most probable pathway for their biogenesis and chemical properties related to the colour modification upon ageing of wines are given.
