摘要
虾青素是类胡萝卜素的含氧衍生物,具有极强的抗氧化活性,能够有效地清除体内的活性氧,在疾病预防和治疗中起着重要作用。本文就虾青素的抗氧化性及其在防癌、抗炎、光保护、增强免疫、延缓衰老等健康和营养方面的作用进行了概括论述,比较了人工合成的虾青素和各种天然虾青素在功能、生物效价和安全性等方面的差异,说明雨生红球藻虾青素在营养和保健品中具有不可替代的应用价值,最后对天然虾青素在营养和医药中的应用前景进行了展望。
Astaxanthin, a kind of keto-carotenoids has strong anti-oxidative capability and can scavenge ROS effectively in human body. In this paper, the functions of astaxanthin as an antioxidant in health and nutrition, covering anti-cancer, anti-inflammatory, UV-light protection, improving immune response and fighting against aging were reviewed in detail. Then, the bioactivity and the safety of natural and synthetic astaxanthin were compared with a conclusion that astaxanthin from Haematococcus pluvialis has the exclusive application value in nutrition and health food. The prospect of natural astaxanthin in pharmaceuticals and nutrition industries were also discussed at finals.
