Five flavonol glycosides, quercitrin (I), isoquercitrin (II), afzerin (III), hyperin (IV) and rutin (V) were isolated from the terrestrial part of Houttuynia cordata collected during the flowering season. The quantitative analysis of the five flavonol glycosides in Houttuynia cordata by high-performance liquid chromatography (HPLC) revealed the following results. (1) All the leaves, spikes and stems contained these five flavonol glycosides, and the content was the highest in leaves. (2) The main flavonol glycosides in spikes were I and IV. (3) The flavonol glycoside contents in leaves before and during the flowering season were about the same.
