Abstract: | In the course of our studies on the polyphenol components of the cultured cells of amacha, seven polyphenol compounds were isolated as pure crystals. The chemical structures of these compounds were determined by analytical methods (IR, UV, NMR and MS spectra) and colour reactions, and the compounds were identified as phyllodulcin, hydrangenol, daphnetin-8-monomethylether, umbelliferone, phyllodulcin-8-β-D-glucoside, hydrangenol-8-β-D-glucoside and skiminin (umbelliferone-7-β-D-glucoside). This is the first report of the isolation of phyllodulcin-8-β-D-glucoside and daphnetin-8-monomethylether from a natural source and of the other compounds from the cells of higher plants in suspension culture. |
