Abstract

The brown seaweed Turbinaria conoides was subjected to sequential extraction with 80% ethanol, aqueous 2% calcium chloride, dilute hydrochloric acid and aqueous 3% sodium carbonate solution. Mannitol and eight polysaccharide fractions I - VIII were separated. The neutral sugar composition and the uronic acid content of each fraction was determined. Results indicate the presence of laminaran in fractions I, II and IV, while fractions III, V, VI and VII are rich in ‘fucans.’
