Objective:The antioxidant activity of synthesized 3-bromo-4,5-dihydroxybenzaldehyde was studied.Method: Radical scavenging effects were determined,with 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical,hydroxyl radical and superoxide anion radical respectively.Result: It was found that 3-bromo-4,5-dihydroxybenzaldehyde had obvious scavenging effect on DPPH radical activity with IC50as 4.49 mg·L-1.It was better than positive controls,Vit C and t-butyl hydroquinone(TBHQ).The scavenging ability on O-2 radical is stronger than TBHQ,with IC50=0.93 g·L-1,while on hydroxyl free radical,weaker than Vc and TBHQ with IC50=122.42 mg·L-1.Conclusion: The antioxidant activity of 3-bromo-4,5-dihydroxybenzaldehyde was obvious and could be developed to a medicine or antioxidant ingredient in food.

3-bromo-4,5-dihydroxybenzaldehyde exhibits strong antioxidant activity, potentially developing as a medicine or food ingredient.
