Abstract: | The unique phenolic carboxylic acids, 4,8-dimethoxy-7-hydroxy-2-oxo-2H-1-benzopyran-5,6-dicarboxylic acid and 2-(4-carboxy-3-methoxystyryl)-2-methoxysuccinic acid were isolated and identified from the whole Sanguisorba minor plant. The known phenolics, gallic acid; ellagic acid; quercetin-3-O-(6"-galloylglucose); beta-glucogallin; 2,3-hexahydroxydiphenoyl-(alpha/beta)-glucose; 1-galloyl-2,3-hexahydroxydiphenoyl-alpha-glucose together with its beta-isomer were also characterized. Structures were established by conventional methods of analysis and confirmed by NMR and ESI-MS spectral analysis. |
