The amounts of five flavonoid glycosides contained in Houttuynia cordata THUNB., quercitrin, hyperin, rutin, isoquercitrin and afzelin were determined by HPLC. Leaves had a high quarcitrin content and the spikes had high quercitrin and hyperin contents, but the stems contained only a little and the rhizomes scarcely any of these flavonoid glycosides. The flavonoid glycoside contents and the glycoside profiles in the leaves remained constant as the plant grew. The total flavonoid glycoside contents (the sum of five constituent contents) in the leaves of a hundred wild materials collected in 84 locations were all between 2 and 4%, and their flavonoid glycoside profiles were all alike. The commercial crude drugs of Chinese origin tended to have higher hyperin contents than Japanese samples.
