Abstract

Toxin profiles of the paralytic shellfish poison (PSP) detected from domestic shellfishes collected at the market and imported. shellfishes were invested by fluorometric HPLC. Total 9 components in PSP were analysed from the imported ark shell, such as saxitoxin (STX), decarbamoylsaxitoxin (dcSTX), gonyautoxin (GTX) - 1,2,3,4,5, Cl and C2. Among those toxins, 7 components except for GTX1,4 were detected from domestic shellfishes and showed different toxin contents and toxin compositions by species. Only C group toxin (Cl +2) contained in short necked clam and hard clam $(0.06\~0.56\;nmole/g)$ which living under soil but, in the blue mussels and oysters which cultured in the open sea water, showed more higher toxicity and complicate toxin compositions. Toxin compositions in bloody clam and purplish washington clam were very different in some samples even in same species. GTX4 and GTX5 were higher in imported scallop and STX was higher in imported ark shell than other species.

2004년 4뭘 셋째 주에 수산시장에서 구입한 국내산의 패류 및 5, 7, 9월에 구입한 수입산 패류를 형광 HPLC에 의해 마비성 패류독의 특성을 분석하였다. 수입산 피조개에서는 마비성 패류독성분 중 Saxitoxin(STX), Decarbamoylsaxitoxin(dcSX), Gonyautoxin(GTX)-1,2,3,4,5, Cl 그리고 C2로 총 9개의 독성분이 검출되었다. 이 독성분 중에서 GTX1과 GTX4를 제외 한 나머지 성분들은 국내산 패류에서도 검출이 되었고, 패류 종류별 서로 다른 함량과 조성을 나타내었다. 뻘 속에서 사는 바지락과 백합의 Cl+2의 함량은$0.06\~0.56\;nmol/g$이 었다. 그러나 양식산 진주담치 와 굴에서는 더 높은 독성과 복잡한 독성분 조성을 나타내었다. 반면, 꼬막과 개조개의 독성분의 조성은 같은 종류의 시료라 할지라도 서로 다르게 검출되었다. GTX1과 GTX5는 수입산 가리비에서 더 높았고, STX는 다른 종류와 비교해서 수입산 피조개에서 더 높게 검출되었다.
