A rapid HPLC method with fluorescence detection of pectenotoxin-2 (PTX2), a polyether macrolide toxin, in microalgae is presented. A dienophile reagent, DMEQ-TAD, was used for precolumn fluorescence labeling. PTX2 could be quantitatively detected in the range 1-200 ng. This method confirmed the occurrence of PTX2 in net haul samples mostly composed of dinoflagellates Dinophysisspp. collected in the Adriatic Sea, Italy and Mutsu Bay, Japan.
