Isolation of 9-hydroxy-delta-tetradecalactone from lipid A of Pseudomonas diminuta and Pseudomonas vesicularis.
A lipid component was isolated from the fatty acid fraction of acid hydrolysates of lipid A derived from Pseudomonas diminuta JCM 2788 and Pseudomonas vesicularis JCM 1477 lipopolysaccharides. By structural analysis of the lipid and its trimethylsilyl and acetyl derivatives by thin-layer chromatography, gas chromatography-mass spectrometry, mass spectrometry, infrared spectrometry and 13C-NMR, it was identified as 9-hydroxy-delta-tetradecalactone.
