| Abstract: | The flavonoids,which were extracted from water hyacinth,were characterized by FTIR and some reactions of qualitative analysis.The antioxidant activity and the scavenging free radical property were also investigated.The results suggested that the extracted flavonoids had an envident oxidation resistance to lard oil,which was stronger than citric acid.Besides,it also had a perfect scavenging effect on hydroxyl free radical by Fenton reaction. |
