Abstract: Seven compounds were isolated from Actinidia kolomikta(Rupr.et Maxim.)Planch.. The structures of the compounds were deduced by spectroscopic methods(1D NMR, 2D NMR, MS) as kaempferide-3-O-rutinoside(Ⅰ), kaempferide-7-O-(4"-O-acetylrhamnosyl)-3-O-glucoside(Ⅱ), kaempferide-7-O-(4"-O-acetylrhamnosyl)-3-O-rutinoside(Ⅲ), kaempferol-3-O-glucoside(Ⅳ), kaempferol-3-O-rutinoside(Ⅴ), kaempferide-3-O-glucoside(Ⅵ) and kaempferide-7-O-rhamnosyl-3-O-rutinoside(Ⅶ). Compounds Ⅰ—Ⅲ are new compounds, compounds Ⅰ—Ⅳ were obtained from this plant for the first time.
