Abstract:
Objective: To investigate the anti-oxidation activity of astaxanthin. Method: Free radical scavenging properties were investigated in modified chemical system. The antioxidation activity of astaxanthin and vitamin E for linoleic acid autooxidation, hydroxy radical and DPPH radical was detected by spectrophotometry. Results: Astaxanthin could inhibit autooxidation of linoleic acid effectively and its inhibition and elimination rate to hydroxy radical was higher than vitamin E. The elimination rate was 95.98% at the concentration of 50 ?g/ml astaxanthin. Although the effect of astaxanthin on eliminating DPPH radical was slightly lower than vitamin E, but the elimination rate still high to 97.0% at concentration of 80 ?g/ml. Conclusion: Astaxanthin has obvious anti-oxidation activity.
