It was found that T. ocellatus contained moderate amounts of toxin in skin and viscera, and the highest toxicity scores were 432 MU/g skin and 212 MU/g viscera. The specimens of T. nigroviridus contained weak amounts of toxin in skin, and the highest toxicity score was 124 MU/g. The toxin was partially purified from the toxic specimens of each species by ultrafiltration using a YM-1 membrane, followed by chromatography on Bio-Gel P-2 column. Analyses by electrophoresis, thin layer chromatography, and high performance liquid chromatography showed that the toxin from both species was composed of tetrodotoxin and anhydrotetrodotoxin. |
