  Minerals such as sodium (Na+), potassium (K+) and sulphate were analyzed in red, brown and green abundant seaweeds found along the Coast of Gulf of Mannar, India, during July 2005. A high mean amount of Na+ was recorded in Chlorophyceae followed by Rhodophyceae and Phaeophyceae. The mean value of K+ in the brown and red algae were higher when compared to green seaweeds. A less Na+/K+ ratio indicated high K+ and low Na+ in brown and red algae and a high Na+/K+ ratio in green seaweeds indicated high Na+ and low K+. The sulphate content was variable in the algae studied; the maximum concentration was found in red alga Grateloupia lithophila (162.8 mg g-1 alga dry wt.) and minimum in brown alga Chnoospora implexa (0.88 mg g-1 alga dry wt.).

  Fucoidan is a hetero-polymer of sulfated L-fucose extracted from brown seaweeds, sea urchin, sea cucumber etc. that display diverse bioactivity. In this investigation, yield, total carbohydrate, L-fucose and sulphate content of crude fucoidan extracted from 11 abundantly occurring brown seaweeds along the coast of Gulf of Mannar (Rameswaram regions), India were evaluated by adopting two different methods. A maximum amount of crude fucoidan was recorded from Sargassum wightii (7.15 % alga dry wt.) followed by Dictyota dichotoma, Turbinaria ornata, T. conoides, T. decurrens, Sargassum myriocystum, S. ilicifolium, S. marginatum, Padina boergesenii, P. gymnospora and Stoechospermum marginatum (2.13% alga dry wt.). Highest L-fucose content of 232.5 mg g-1 dry crude fucoidan (23.25% in crude fucoidan ) was extracted in Sargassum wightii among the 11 seaweeds studied. Maximum sulphate content of 98.7 mg g-1 dry crude fucoidan (9.87% in crude fucoidan ) was also recorded in Sargassum wightii. A method that yield maximum crude fucoidan constitute less L-fucose whereas the other method that extracted low crude fucoidan constitute high L-fucose content. Some of the brown seaweeds occurring along the coast of Gulf of Mannar contained potential yield of fucoidan. The yield and quality of fucoidan extracted from seaweeds were depending on the method followed for the extraction. The yield of fucoidan was varied among the brown seaweeds likely to be species specific.
