Abstract: Flavonoids were extracted from glutinous rice tea grown in Huaguo Mountain by solvent extraction and isolated by column chromatography on silica gel. The antioxidant activity in vitro was determined by DPPH free radical scavenging assay. The results indicated that flavonoids from glutinous rice tea had certain free radical scavenging ability. In conclusion, glutinous rice tea has the potential to be developed as an anti-aging and antioxidant health-care tea.
