摘要
Carotenoids are pigments which play a major role in the protection of plants against photooxidative processes. They are efficient antioxidants scavenging singlet molecular oxygen and peroxyl radicals. In the human organism, carotenoids are part of the antioxidant defense system. They interact synergistically with other antioxidants; mixtures of carotenoids are more effective than single compounds. According to their structure most carotenoids exhibit absorption maxima at around 450 nm. Filtering of blue light has been proposed as a mechanism protecting the macula lutea against photooxidative damage. There is increasing evidence from human studies that carotenoids protect the skin against photooxidative damage.

类胡萝卜素是在保护植物免受光氧化过程中起主要作用的色素。它们是有效的抗氧化剂，可清除单线态分子氧和过氧自由基。在人体组织中，类胡萝卜素是抗氧化防御系统的一部分。它们与其他抗氧化剂协同作用;类胡萝卜素的混合物比单一化合物更有效。根据它们的结构，大多数类胡萝卜素在450nm附近表现出最大吸收。已经提出过滤蓝光作为保护黄斑黄斑免受光氧化损伤的机制。人类研究越来越多的证据表明，类胡萝卜素可以保护皮肤免受光氧化损伤。
