| Abstract | Abstract — The present study was designed to explore the total flavonoid and taxifolin contents and the radical-scavenging activity of 50 % ethanol extracts of Polygonum orientale leaves, stems, and seeds by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The extract with higher total flavonoid content has higher radical scavenging activity. Taxifolin (IC 50 = 2.83 µmol/L) has antioxidant activity stronger than that of rutin (IC 50 = 3.08 µmol/L). The free radical-scavenging potentials of chloroform, ethyl acetate, water, ethanol, and methanol extracts of Polygonum orientale seeds were also investigated. The free radical-scavenging abilities of various extracts were determined as: methanol> ethanol> water> ethyl acetate> chloroform. |
