Description:
Paralytic Shellfish Poison (saxitoxin and derivatives) was extracted by HCL method from frozen scallops. The samples were collected from coastal areas of Iwate prefecture- Japan. Toxicity of the samples was determined with mouse bioassay method. Intra peritoneal injection was done to dry strain 19-21 grams male mouse, and death time was listed. In conclusion, 33.80, 38.40, 31.20 MU/g (or 777, 883, 718 STX/l00gr) were obtained respectively as the toxicity of the samples of three different sampling areas. The toxicity for the areas was 9.7, 11 and 9 times more than standard level (80STX/100g) and very dangerous for human consumption. The kind of toxin was determined by comparing HPLC graph of sample with standard saxitoxin HPLC graph.
