Abstract

Two new dimeric phenolic conjugates, 2,3-di-O-dehydrodigallicmonocarboxyl---glucopyranose and ellagic acid 3,3'-dimethylether-4-0- were isolated from the debarked heart wood of Tamarix tetragyna (Tamaricaceae) along with the known phenolic compounds, isoferulic acid, ferulic acid, gallic acid, gallic acid 4-methyl ether, syringic acid, ellagic acid 3,3'-dimethyl ether and ellagic acid. All structures were determined mostly by ESI-MS, ID and 2D-NMR spectroscopy.
