FLAVONOIDS FROM FLOWERS OF AMESIODENDRON CHINENSE (SAPINDACEAE)
Keywords:Flowers, Amesiodendron chinense, chrysoeriol, catechin, quercetin 3-O-β-D-glucoside, astragalin, and kaempferide-3-O-β-D-glucopyranoside.
From the flowers of Amensiodendron Chinese (Merr.) Hu, six known flavonoids, (-)-catechin (1), (-)-epi-catechin (2), chrysoeriol (3), quercetin-3-O-β-D-glucopyranoside (4), astragalin (5) and kaempferide-3-O-β-D-glucopyranoside (6) were isolated. Their chemical structures were elucidated by analysis of the physicochemical parameters, the NMR and mass spectral data, and comparison with those reported in the literatures.
