Abstract: This study aimed to assess the effect of Aronia melanocarpa on antioxidant capacity of liver and kidney in mice. A total of 16 mice were assigned into two groups： an experimental group （n =8） received a 3% Aronia melanocarpa solution for consecutive 8 weeks, and a control group （n=8） received a distilled water for the same time duration. The activities of superoxide dismutase （SOD） and glutathione （GSH） as well as the content of malondialdehyde （MDA） in liver and kidney of the mice in both experimental group and control group were determined. The results showed that compared with the control group, the experimental group had elevated activity of SOD in the liver tissue; the MDA content and GSH activity in kidney tissue of the experimental group were obviously reduced and increased compared to the control group, respectively. It was indicated that the Aronia melanocarpa had certain antioxidant activity.
