我国海藻中抗氧化活性物质的研究进展

Advances in studies of antioxidant active substances from seaweed of China

近年来一些研究人员从海藻中分离出多种具有抗氧化活性的物质,如海藻多糖、多酚、超氧化物歧化酶、不饱和脂肪酸、牛磺酸、维生素类等,并对它们的来源、在海藻中的含量、结构、活性及作用机理等方面进行了研究。地球上海洋资源丰富,海藻种类繁多,海藻中富含的抗氧化活性物质具有活性作用强、结构复杂、副作用低等优点,为海洋医药与生物制品的开发提供了良好的天然产物来源。本文综述了海藻中抗氧化活性物质的研究进展,并结合相关研究做出了分析和探讨,以期为海洋医药和生物制品的开发提供理论基础。

In recent years, a broad range of antioxidant active substances had been isolated and characterized from seaweed, including polysaccharides, polyphenols, superoxide dismutase, unsaturated fatty acids, taurine and vitamins, etc. Their origin, contents, structures, biological activities and corresponding mechanisms had been studied. Due to wide variety of supply and the advantages of potent antioxidant activities, complex structures and low side effects, the seaweed could be an ideal natural source for the development of marine drug and biological products. The research progress of antioxidant active substances in seaweed was systematically reviewed in this paper. These substances with the relevant researches were analyzed and discussed in an effort to provide a theoretical basis for the development of marine pharmaceutical and biological products.
