Fluorometric measurement of yessotoxins in shellfish by high-pressure liquid chroraatography

Abstract

A rapid HPLC method with fluorescence detection of yessotoxin (YTX) and its two analogs (45-OHYTX and norYTX) in mussels and scallops is presented. A dienophile reagent, DMEQ-TAD, was used for fluorescence labeling. YTX was measured in the range 1–100 ng. The method confirmed the occurrence of YTX and 45-OHYTX for the first time in mussels from Chile and New Zealand. © 1997, Taylor & Francis Group, LLC. All rights reserved.
