Abstract Organic bound arsenic is enriched in aqueous extracts prepared from marine raw materials. The extracts have been chromatographed in four different thin‐layer chromatographic (t.l.c.) systems. All extracts prepared by boiling and enzymic hydrolysis of heat treated and fresh raw material contain one major organo‐arsenic compound with the same t.l.c. behaviour in all systems. Aqueous extracts prepared from oil from seaweed and from fish and treated with constant boiling hydrochloric acid also contain one compound with identical behaviour in all t.l.c. systems. The chromatographic behaviour of the latter organoarsenic compound is, however, different from that of the organoarsenic compound in the aqueousract.
