Macrocarpals in Eucalyptus SPP. As Attachment-Inhibitors Against the Blue Mussel

Abstract

We have isolated and characterized a new macrocarpal named macrocarpal K, an isopentylphloroglucinol-β-eudesmol adduct. We have also tested six macrocarpals, including macrocarpal K for attachment-inhibiting activity against the blue mussel Mytilus edulis galloprovincialis. Macrocarpals A, B, E, am-1, H and K showed potent attachment-inhibiting activity against the blue mussel, which was 1–3 times higher than the standard antifoulant CuSO₄.
