title: Polyphenols of Egyptian Rosaceae plants--two new flavonoid glycosides from Sanguisorba minor Scop.
abstract: Two new flavonol glycosides, 8-methoxyquercetin-3-O-beta-glucosyl-(1'"-2")-O-beta-glucoside and kaempferol-3-O-[2'"-galloyl-O-beta-glucosyl-(1'"-2")-O-beta-glucoside)], together with five known quercetin and kaempferol 3-O-mono-glycosides, were isolated and identified from the aerial parts of Sanguisorba minor Scop. (Rosaceae). All structures were determined by routine methods of analysis and confirmed mostly by negative ESI-MS, 1H- and 13C NMR.
