CAMACHO, Ángel et al. Identification of some secondary metabolites from the ethyl-acetate-extract of the octocoral, Muricea sp. Saber [online]. 2014, vol.26, n.2, pp.189-195. ISSN 1315-0162.

Some chromatographic fractions obtained from the ethyl-acetate-extract of the unidentified octocoral species of the genus, Muricea, showed antibacterial activity against Escherichia coli, Salmonella enteritidis, Citrobacter freundii, Staphylococcus aureus, and Bacillus subtlis, which indicates the presence of bioactive compounds in it. The GC/MS analysis of some fractions obtained by continuous chromatographic separation, allowed identification of metabolites, such that: (Z)-9-octadecenoic acid methyl ester, octadecenoic acid methyl ester, 1-methyl-4-ethoxy-δ(3)-pyrrolin-2-one, endo-1-bourbonanol, dibutylphtalate, 4,5-epoxy-1-isopropyl-4-methyl-1-cyclohexene, 1,3,3-trimethyl-7-oxabcyclo[2.2.1]heptane-2-carboxylic acid ethyl ester, 2,6-dimethyl-2-trans-6-octadiene, farnesol, 3β-cholesta-5,22-dien-3-ol, cholesterol, (3β,22E,24S)-ergosta-5,22-dien-3-ol, (3β,5α)-2-methylenecholestan-3-ol, 3-hidroxylongifolol, by comparison with the WILEY and NIST databases and the study of the fragmentation patterns of their mass spectra.
