| Description | Five flavonol glycosides, including a new glutaryl-conjugated compound, were isolated from methanolic extract of the endemic Balkan species Astragalus thracicus Griseb. Based on NMR and MS spectra, one new compound was identified as kaempferol-3-O-[beta-glucopyranosyl-(1 -> 4)-alpha-rhamnopyranosyl-(1 -> 6)-(2 ''-3-hydroxy-3-methyl-gutaroyl)-beta-galactopyranoside)] (1). The other compounds, all known, were identified as mauritianin (2), kaempferol-3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-beta-galactopyranoside (3), kaempfeml-3-O-beta-apiofuranosyl-(1 -> 2)-beta-galactopyranoside (4), and quercetin-3-O-beta-apiofuranosyl-(1 -> 2)-beta-galactopyranoside (5). All of them, except 2, were found for the first time in a representative of genus Astragalus. |
