  Eight phenolic compounds (castalin, castalagin, vescalagin, kurigalin, 5-O-galloylhamamelose, (3', 5'-dimethoxy-4'-hydroxyphenol)-1-O-beta-D-(6-O-galloyl)glucose, chestanin, and acutissimin A) were isolated from chestnut bark and their structures elucidated on the basis of spectroscopic analyses. Evidence for strong intermolecular associations of 5-O-galloylhamamelose is presented on the basis of NMR and mass spectroscopic data.
