摘要：

Antioxidative flavonoids and flavonoid glucoside were isolated from the leaves of Polygonum hydropiper, a culinary herb. The flavonoid la was identified as 7,4'-dimethylquercetin, Ib as 3'-methylquercetin, Ic as quercetin, and the flavonoid glucoside Id as isoquercitrin on the basis of chemical and spectroscopic evidence. The antioxidative activities measured by a ferric thiocyanate method were in the order Id > Ia > Ic > Ib.
