Sargassum muticum have shown the potential of hydrocarbon and fatty acid compounds in antifouling activities, compounds such as galactolipids and palmatic acid, 1-tetradecene or 1-hexadecene. Moreover, the peak production of antifouling compounds is during the spring. Antioxidant compounds: "Sargassum muticum" is rich in antioxidant compounds such as phenolic compounds (cathechins, phlorotannins, quercetins), pigments (fucoxanthin) and vitamins(vitamin C, K, E in the forme of alpha-tocophérol and gamma-tocopherol). Applications are possible in pharmaceutics, cosmetics and health fields thanks to the antioxidant activities of these molecules. Sargassum muticum Sargassum muticum, commonly known as Japanese wireweed, is a large brown seaweed of the genus "Sargassum". It
