“…Phlorotannins are phenolic compounds exclusive of marine seaweeds, but these organisms, particularly brown algae, also contain a variety of components with antioxidant action (such as polyunsaturated fatty acids, proteins, pigments, vitamins, polysaccharides and carotenoids). The phlorotannins and algal polysaccharides exhibit anticoagulant, antiviral, antioxidative, anticancer, antiinflammatory and immunomodulatory actions, and could have potential for the development of nutraceutical, pharmaceutical and cosmeceutical products (Batista González et al, 2009;Balboa et al, 2013;Thomas and Kim, 2013). Valorization and utilization of the constituents of the brown macroalga Sargassum muticum was proposed, since the solvent extracts (Kim et al, 2007) and the soluble fractions obtained after autohydrolysis (González-López et al, 2012) were active in vitro antioxidants.…”
