Abstract
When the conjugated keto-carotenoids, either astaxanthin or canthaxanthin, are added to rat liver microsomes undergoing radical-initiated lipid peroxidation under air, they are as effective as alpha-tocopherol in inhibiting this process. This contrasts with the effect of beta-carotene, which is a much less potent antioxidant when added in this system, without the addition of other antioxidants.
摘要
当将共轭酮类胡萝卜素（虾青素或角黄素）添加到在空气中进行自由基引发的脂质过氧化反应的大鼠肝微粒体中时，它们在抑制这一过程方面与α-生育酚一样有效。这与β-胡萝卜素的作用形成对比，在不添加其他抗氧化剂的情况下，β-胡萝卜素添加到该体系中时是一种效力低得多的抗氧化剂。
