| Abstract: | OBJECTIVE: To study the chemical constituents of flavonoids from Polygonum capitatum. METHODS: Compounds were isolated with silica gel and polyamide chromatography and their structures were determined by spectral analysis and chemical evidence. RESULTS: Four compounds were obtained and identified as quercetin （Ⅰ）, quercitrin（Ⅱ）, Hirsutine（Ⅲ）, quercetin 3rhamnoside 2″gallate（Ⅳ）. CONCLUSION: All the compounds were isolated from this plant for the first time. |
