Abstract
Paralytic shellfish poisoning (PSP) toxins are highly toxic natural compounds produced by dinoflagellates commonly present in marine phytoplankton. Shellfish accumulate PSP toxins during toxic algal blooms. PSP poses a significant public health threat and economic loss to the shellfish industry. For this reason, many methods have been developed to analyse PSP toxins in suspected toxic shellfish samples. In our study, we simplified the sample preparation method and set up a rapid and accurate high-performance liquid chromatography (HPLC) system to detect PSP toxins in algae and shellfish on a routine basis. The toxins profile of two strains of dinoflagellate Alexandrium minutum and shellfish samples collected from southwestern locations in Taiwan has been analysed with this HPLC method. Only A. minutum and purple clam Hiatula rostrata contained PSP toxins, with GTX-1, 2, 3, 4 being the major toxins. © 2002 Elsevier Science Ltd. All rights reserved.
