Abstract Cladostephus verticillatus , a brown seaweed belonging to the genus Cladostephaceae , was collected from Nobska Point, La Jolla, California, during 1955 and air‐dried. Alcoholic, aqueous, and sodium carbonate extracts have been analysed. The major carbohydrates are alginic acid, laminarin, fucoidin and mannitol. Quantitative estimations of the fucoidin and laminarin content (2% and 20% of dried weed, respectively) of Cladostephus spongiosus collected near Plymouth have also been carried out.
