Study on free radical scavenging property of astaxanthin
Objective:To investigate the anti-oxidation activity of astaxanthin and compared with VC.Method:Free radical scavenging properties were investigated in modified chemical system.The antioxidation activity of astaxanthin and VC for DPPH radical,hydroxy radical and superoxide anion was detected by spectro-photometry.Results:The inhibition and elimination rate of astaxanthin to ·OH and O 2-·was higher than VC.Although the effect of astaxanthin on eliminating DPPH·radical was slightly lower than VC,but the elimination rate still high to 95.0% at concentration 90 μg/mL.Conclusion:Astaxanthin has obvious anti-oxidation activity.
