Abstract:

Four new acetylated flavonoids, 4'-methoxyl-quercetin-7-(4"-O-acetylrhamnosly)-3-O-β-D-glucopyranoside(1), kaempferide-7-O-(3"-O-acetylrhamnosyl)-3-O-rutinoside(2), kaempferol-7-O-(4"-O-acetylrhamnosyl)-3-O-rutinoside(3), 4'-methoxyl-quercetin-7-(4"-O-acetylrhamnosyl)-3-O-rutinoside(4) were isolated from the extracts of the leaves of Actinidia Kolomikta(Rupr.et Maxim.) Planch. Their structures were elucidated by application of chemical and spectroscopic analysis including HRESI-MS, 1H-1H COSY, HMQC and HMBC.
