摘要
许多研究已经表明,类胡萝卜素是分布最广泛、最重要的一类光辅助合成色素。类胡萝卜素具有多种生物学功能:作为化学保护剂可抵抗由植物自身叶绿素的光敏氧化作用引起的有害作用,给人体补充β-胡萝卜素可有效降低心血管疾病和癌症的发生概率,高摄入富含类胡萝卜素的饮食和降低白内障发生的危险之间有重要联系(Bendich,
Carotenoids are one group of the most widespread and important pigments, and one of the major sources of natural carotenoids is seaweed. By chemical extraction, chromatography and spectroscopy, identification and quantification of carotenoids were carried out in various seaweeds, including Chlorophyta, Rhodophyta and Phaeophyta. It was demonstrated that carotenoid content in green algae is the highest, usually two or three times more than the other two. The structural analogs of carotenoids in green algae are also more variable than those in red and brown algae. The major carotenoids are zeaxanthin and lutein in green algae, zeaxanthin and violaxanthin in red algae, fucoxanthin and violaxanthin in brown algae. Among the seaweeds investigated, Codium fragile is the most potential resources for carotenoids with high content and structural variations. The chemical composition and contents of carotenoids could be used as possible markers of chemotaxonomy in marine algae.
