Abstract:

Two long-chain fatty acids, 27-oxo-octacosanoic acid (28:0(27-oxo)) and heptacosane-1,27-dioic acid (27:0-dioic) were identified for the first time in phenol-chloroform-petroleum ether extracts of Legionella pneumophila, indicating that they are constituents of lipopolysaccharide. The fatty acids were characterised by combined gas-liquid chromatography/mass spectrometry and proton nuclear magnetic resonance spectroscopy. Moreover, minor amounts of 29-oxo-triacontanoic (30:0(29-oxo)) acid and nonacosane-1,29-dioic acid (29:0-dioic) as well as 27-hydroxy-octacosanoic acid (28:0(27-OH)) were present in the phenol-chloroform-petroleum ether extract.
