英文摘要: Flavones are a group of plant secondary metabolites with multiple biological properties. In the present study, 5,6,7,8-tetrahydroxyflavone (5,6,7,8-THF) was synthesized and characterized. In vitro antioxidant study, the effect of 5,6,7,8-THF on total antioxidant activity, reducing power, DPPH radical scavenging, ABTS radical scavenging, superoxide radical scavenging, hydroxyl radical scavenging, nitric oxide radical scavenging, and ferrous chelating activities was examined. According to the results, 5,6,7,8-THF showed excellent free radical scavenging effect and reducing power but weak the ferrous chelating activity. In conclusion, 5,6,7,8-THF can be regarded as an excellent source of antioxidants.
