Study on facilitating further utilization of sea anemones as new marine resources

对不同种类的海葵进行了抗蟹肽毒素的筛选。我们成功地从3种海葵中分离并分析了9种肽毒素的一级结构。有趣的是，从Oki群岛沿岸食用的深海海葵中分离出6种肽类毒素，其中5种肽类毒素的化学结构与从海葵中分离出的已知毒素完全不同。这表明新型肽毒素在深海海葵中存在的范围比预期的要广泛。

The screening of peptide toxins with activity against freshwater crab were performed on various sea anemones. We have successfully isolated and analyzed the primary structure of 9 peptide toxins from 3 species of sea anemones. Interestingly, 6 peptide toxins were isolated from the deep-sea anemone which is eaten as food in the coast of Oki islands, and the chemical structure of 5 peptide toxins of them were completely differ from the known toxins have been isolated from sea anemones. This suggests that novel peptide toxins exist in deep-sea anemones more widely than expected.
