[Method] MDA content was determined by thiobarbituric acid colorimetric method; mitochondrial swelling degree was determined by spectrophotometry; the superoxide anion radical scavenging ability was determined using reduced coenzyme I-tetrazolium-phenazine methosulfate as the superoxide anion generation system. Mice were hypodermically injected in the back and neck with D- galactose, after 50 d, the effects of AEO on the activities of superoxide dismutase （SOD）, glutathione peroxidase （GSH-Px） and anti-hydroxyl radicals in mouse liver were determined using kits. [Result] AEO can efficiently reduce the liver injury and inhibit mitochondrial swelling induced by Fe2＋-L-Cys, which can also scavenge superoxide anion and improve the activities of antioxidant enzymes. [Conclusion] This study provided scientific basis for the development and application of AEO resources.展开更多
