Lipid extracts of Laurencia obtusa from eastern Sicily were examined by gas chromatography/mass spectrometry in order to investigate their composition in halogenated products and a marked variability has been found in specimens from different sites, while life history or season had a minor influence.

Abstract

Lipid extracts of Laurencia obtusa from eastern Sicily were examined by gas chromatography/mass spectrometry in order to investigate their composition in halogenated products and a marked variability has been found in specimens from different sites, while life history or season had a minor influence. In different habitats and types of substrate and flora, within a few kilometers distance, a completely different array of metabolites has been observed. Some of these compounds, namely obtusin, obtusadiol and obtusenyne, were reported in L. obtusa from other Mediterranean locations. A new compound, laurencienyne, is a major component in individual specimens collected at Castelluccio, whereas it is absent in specimens from other sites.
