【Abstract】 AIM To study the free radical scavenging effects of artemisia flavonoids. METHODS Scavenging activities to superoxide anion radical(O · 2) and hydroxyl radical(·OH) were measured by electron paramagnetic resonance(EPR). RESULTS Artemisia flavonoids has different scavenging activity to O · 2 and ·OH, and there is a parallel dependent relationship between the concentration and the scavenging effects. CONCLUSION Artemisia flavonoids has anti oxidant activity.更多还原
