Abstract: 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.
