It was found that the three species of gastropods contained moderate amounts of toxin in edible portion only, and the highest toxicity score was 18 MU/g for O. miniacea, 10 MU/g for O. mustelina, and 27 MU/g for O. nirasei. 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 HPLC, GC–MS and LC–MS showed that the toxin from O. miniacea, O. nirasei and O. mustelina contained TTX, and related compounds 4-epi TTX and anhydro-TTX. The paralytic shellfish poisons were not found. |
