Abstract:
We isolated the highly potent attachment-inhibitors (three times more active than standard CuSO4 in the blue mussel assay), trans-6-, 8-, and 10-shogaols, from a hexane extract of the roots of ginger, Zingiber officinale Roscoe. Trans-8-shogaol showed the highest antifouling activity comparable with that of tributyltin fluoride (TBTF), which is recognized as one of the most effective antifouling agents, in the conventional submerged assay.
