Abstract. The biochemical composition of Fucus vesiculosus and Ascophyllum nodosum from the Barents, White and Baltic Seas has been investigated. It has been determined that the algae collected in the White Sea, contains more protein and free amino acids than the rest of the studied plants. The content of mannitol in F. vesiculosus and A. nodosum from the White and Barents Seas is 8-12 % (dry weight). The greatest quantity of polysaccharides (alginates and fucoidan) is contained in F. vesiculosus from the Baltic Sea due to combination of low salinity and minimum intensity of water movement. The maximum content of polyphenols (18.6 %) has been found in F. vesiculosus from the White Sea. The data can be used to optimize the technologies of BAS from brown algae.

Keywords: fucoids, mannitol, protein, free amino acids, polysaccharides, polyphenols
