Abstract: Microcystins (MCs) produced by blue-green algae, is one of the algal toxins with features of highest frequency and production. MCs could cause serious multi-organ toxicity, genetic toxicity and carcinogenicity. Monitoring of MCs residue in aquatic products is important for evaluating the potential risk for human beings. Therefore, the trace analytical technique of MCs is needed. In this paper, the progress of the microcystins extraction, purification and analytical techniques is reviewed.

Key words: aquatic products, determination, extraction, purification,
