An increase in polysaccharides' sulphate content was registered from winter to summer, and higher values were obtained for <i>Osmundea</i> sp. In turn, the monosaccharide composition constantly changed with a decrease in glucose in <i>Osmundea</i> sp. from spring to winter. For <i>Codium</i> sp., a higher increase was noticed regarding glucose content in the Galician and Portugal coasts. Galactose was the major monosaccharide in all the samples, remaining stable in all seasons and collection sites.
