Abstract

Samples of the brown alga Caulocystis cephalornithos, from five locations in southern and southeastern Tasmania, were investigated for comparison of their acetogenin content. In contrast with previously studied brown algae, including mainland Australian collections of C. cephalornithos, Tasmanian collections of C. cephalornithos were found to contain unusually high levels of tridec-1-ene, a hydrocarbon not previously reported from a marine alga. The novel metabolite (E)-nonadec-3-en-2-one was also isolated. Compounds previously described from this alga were present, together with a suite of homologues not previously observed in this species. The compounds present suggested that the alkyl chain of the orsellinic acid derivatives was present prior to cyclisation. Large variations in relative metabolite content were observed both within and between collection sites. © 2006 Elsevier Ltd. All rights reserved.
