Methods for the extraction and isolation of fucoidin from the common brown algae indigenous to Great Britain have been worked out on the laboratory scale, with a view to the ultimate development of a process suitable for large‐scale production. Extraction involves treatment of the weed with hydrochloric acid at 70° for one hour at pH 2.0–2.5. The crude fucoidin is isolated by fractional precipitation with alcohol, and purified by treatment with formaldehyde.
