Anti-oxidative activities of mytiloxanthin, a metabolite of fucoxanthin in shellfish and tunicates, were investigated. Mytiloxanthin showed almost the same activities for quenching singlet oxygen and the inhibition of lipid peroxidation as those of astaxanthin, which is a well-known singlet oxygen quencher. Furthermore, mytiloxanthin showed excellent scavenging activity for hydroxyl radicals and this activity was markedly higher than that of astaxanthin.
研究人员对贝类和海鞘中岩藻黄质的代谢产物岩藻黄素的抗氧化活性进行了研究。岩藻黄素在淬灭单线态氧和抑制脂质过氧化方面的活性与虾青素(一种广为人知的单线态氧淬灭剂)几乎相同。此外,岩藻黄素对羟基自由基的清除活性极佳,且明显高于虾青素。
