The antioxidant activity of 28 natural and synthetic hydroxyflavonoids was estimated through the 1,1-diphenyl-2-picrylhyrazyl (DPPH) radical, superoxide scavenging activities and lipid peroxidation inhibition. The result showed the hydroxylation pattern had close relationship with the appearance of activities.
