摘要：

Three hydrophilic flavonoids were isolated and identified from leaves of Polygonum hydropiper as quercetin 3-sulphate, isorhamnetin 3,7-disulphate and tamarixetin 3-glucoside-7-sulphate. The structures were established by chemical and spectral evidence, and their antioxidative activity and effect on the generation of superoxide anion evaluated.
