Abstract
Alkaline oxidation of paralytic shellfish toxins with ten-butyl hydroperoxide yielded highly fluorescent derivatives. Even gonyautoxins I and IV and neosaxitoxin, which were nonfluorescing by previously proposed hydrogen peroxide oxidations, were successfully converted to fluorescent compounds. A continuous shellfish toxin analyzer was constructed by incorporating the reaction into a high pressure liquid chromatographic system. The limit of detection was within the range of 0.04 ~ 2.2 nmol for gonyautoxins I ~ V, neosaxitoxin and saxitoxin.This publication has 1 reference indexed in Scilit:
