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
Sargassum muticum observed in temperate environments. "Sargassum muticum" grows from half-tide to infralittoral areas (to a depth of 10 m.). It is fixed on solid substrates like rocks, stones, shells. It is highly tolerant towards temperature and salinity variations. The optimal temperature is between 17 and 20 °C but it tolerates -9 and 30 °C. Originally from Japan, it is thought to have gained worldwide distribution through being transported with Japanese oysters ("Crassostrea gigas"). "Sargassum muticum" was introduced to the Californian coast in the 40's and in Europe in the 70's (The species was first found in the British Isles in the
