Flavonoid compounds from Pyrus communis L. flowers.
Five flavonoid glycosides: kaempferol 3-O-beta-D-glucopyranoside (IV), isorhamnetin 3-O-beta-D-glucopyranoside (V), isorhamnetin 3-O-beta-D-(6''-O-alpha-L-rhamnopyranosyl)-glucopyranoside (VIII), 8-methoxykaempferol 3-O-beta-D-(2''-O-alpha-D-glucopyranosyl)-glucopyranoside (VI), 8-methoxykaempferol 3-O-beta-D-(2''-O-alpha-L-rhamnopyranosyl)-glucopyranoside (VII) and chlorogenic acid (IX) were isolated from the flowers naturally growing Pyrus communis L. They were identified by chemical and spectroscopic methods.
