Abstract:
:Phytochemical investigation of chloroform extract from the leaves of the marine plant Posidonia oceanica (L.) Delile (Posidoniaceae), yielded posidozinol, a new methylated sesquiterpene along with β-sitosterol and four known fatty acids: palmitic, palmitoleic, oleic and linoleic acids. The structure elucidation has been established on the basis of 1D- and 2D-NMR spectroscopy, GS/MS and ES mass spectrometry. Antibacterial effects of crude extracts from P. oceanica were evaluated against: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and Micrococcus luteus microorganisms.
