title: Flavonoids from the flowers of Aesculus hippocastanum.
abstract: The flavonoids, kaempferol derivatives: 3-O-alpha-arabinofuranoside, 3-O-beta-glucopyranoside, 3-O-alpha-rhamnopyranoside, 3-O-alpha-rhamnopyranosyl (1 --> 6)-O-beta-glucopyranoside and quercetin derivatives: 3-O-alpha-arabinofuranoside, 3-O-beta-glucopyranoside, 3-O-alpha-rhamnopyranosyl (1 --> 6)-O-beta-glucopyranoside, were isolated from the flowers of Aesculus hippocastanum and identified. The structures of these compounds were confirmed by a chemical analysis and spectrophotometric methods (UV, 1H-, 13C-NMR, ESI-MS). The presence of free aglycones: kaempferol and quercetin was confirmed chromatographically by comparison with standards.
