Abstract

ORDAZ, Gabriel et al. Analysis by GC/MS and antimicrobial activity of some chromatograp hic fractions of the Pseudopterogorgia acerosa ethyl acetate extract. Saber [online]. 2014, vol.26, n.1, pp.50-56. ISSN 1315-0162.

Psudopterogorgia acerosa, showed antimicrobial activity against Salmonella enteritidis, Bacillus subtlis, Staphylococcus aureus and Citrobacter freundii bacteria and the fungus Candida albicans, indicating the presence of bioactive constituents in these fractions. Moreover, the GC/MS analysis of some subfractions obtained through continuous chromatographic separation., allowed the identification of the constituents: pristane, bis(3,5,5-trimethylhexyl) ether, 4-octadecanolide, tricloroeicosylsilane, (2-endo,7-exo)-7-ethyl-2,4-dimethyl- 6,8-dioxabycicle[3,2,1]oct-3-ene,1-methoxy-12-octoherbertene, butylphtalylbutylglycolate, N-methyl-N-(4-(4- methoxy-1-hexahydropyridil)-2-butynyl)acetamide, diisobutylphtalate, 3-(4-(diphenylmethyl)phenyl)-1-phenyl- 4,4-dimethyl-1-pentanone, by comparison with WILEY databases and the study of the patterns of fragmentation of their mass spectra.
