bicyclo[4.4.0]decane oxygenated sesquiterpenes from eryngium maritimum essential oil.investigation of the essential oil of the aerial parts of eryngium maritimum l. from corsica led to the isolation of one known sesquiterpene ( 1) and three new oxygenated sesquiterpenes with a muurolane or cadinane skeleton ( 2- 4). structure assignments of 4 βh -muurol-9-en-15-al ( 1), 4 βh -cadin-9-en-15-al ( 2), 4 βh -muurol-9-en-15-ol ( 3) and 4 βh -cadin-9-en-15-ol ( 4) were carried out by gc/ms (ei and ci) and comprehensive 1d and 2d nmr spectroscopy. antibacterial activity of eryngium m ...201222258696
chemical compositions of the essential oils of aerial parts of chamaemelum mixtum (l.) alloni.the chemical compositions of the aerial parts essential oils of chamaemelum mixtum (l.) alloni from corsica and sardinia were investigated employing gas chromatography and gas chromatography/mass spectrometry. the structure of (z)-heptadeca-9,16-dien-7-one, a natural compound not previously described, was elucidated by gas chromatography/mass spectrometry (electron impact and chemical ionization) and one-dimensional and two-dimensional nuclear magnetic resonance spectroscopy. the variation in ch ...201222225420
