Astaxanthin of antioxidative ability was stronger than f3-carotene. The purpose of this study was to examine the effect of astaxanthin supplement on antioxidative status in senescence accelerated mice (SAMP8). Six-month-old male mice were divided into three groups: casein diet group (control group) and casein diet supplemented with 0.01%, 0.025% Astaxanthin. After 16 weeks feeding, body weight and food intake were performed during the experiment. The superoxide dismutase (SOD) activity of liver and brain were analyzed after sacrificed. The results showed that body weight and food intake were no significantly among three groups. The SOD activity of liver in the 0.025% Astaxanthin group was higher than control group (P<0.05). The SOD activity of brain was no significantly among three groups, but in the 0.025% Astaxanthin group was higher than 0.0 1% Astaxanthin and control group. In summary, we conclude the supply of Astaxanthin may improve antioxidative system on liver and brain in SAMP8 mice.
