Studies on chemical constituents of leaves of actinidia kolomikta

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 double prime -O-acetylrhamnosyl)-3-O-glucoside (II), kaempferide-7-O-(4 double prime -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.
