Alcoholic extracts of Fucus vesiculosus contain small quantities of low molecular weight polyphenols derived from phloroglucinol and 2,2\u2032,4,4\u2032,6,6\u2032-hexahydroxybiphenyl. 1H and 13C nmr were used to identify two of these as 4-(2\u2032\u2032,4\u2032\u2032,6\u2032\u2032-trihydroxyphenoxy)-2,2\u2032,4\u2032,6,6\u2032-pentahydroxybiphenyl and 4-(2\u2032\u2032-(2\u2032\u2032\u2032,4\u2032\u2032\u2032,6\u2032\u2032\u2032-trihydroxyphenoxy)-4\u2032\u2032,6\u2032\u2032-dihydroxyphenoxy)-2,2\u2032,4\u2032, 6,6\u2032-pentanydroxybiphenyl.Peer reviewed: YesNRC publication: Ye
