The extraction and clean‐up procedures developed to isolate the water‐soluble arsenic species present in the marine macroalga Fucus distichus , from British Columbia, Canada, are described. The arsenic species were extracted into methanol and then subjected to gel‐permeation and ion‐exchange chromatography. Fractions high in arsenic were identified by using graphite furnace atomic absorption spectroscopy (GF‐AAS), and further investigated by using high‐performance liquid chromatography coupled to inductively coupled plasma–mass spectrometry (HPLC–ICP MS). By using different HPLC columns and mobile‐phase conditions, the four major arsenic‐containing compounds present in the macroalga were positively identified as arsenosugars; one minor compound remained unidentified. © 1997 John Wiley & Sons, Ltd.
