The nucleic magnetic resonance and mass spectrum analyses as well as several kinds of chromatographies clearly showed that the purified toxins were saxitoxin and neosaxitoxin. Tetrodotoxin, which was detected by high performance liquid chromatography analysis, could not be isolated. These findings show that saxitoxins and tetrodotoxin are more widely distributed in aquatic organisms than previously thought.
