Gas Chromatographic Characterization of Frequently Occurring Sesqui-Terpenes in Essential Oils,tion of frequently occurring sesquiterpenes in essential oils. The standard deviation, calculated from the relative retention factors of the same sesquiterpene, determined in different oils, did not exceed 6 × 10..

The sesquiterpene alcohol, α-bisabolol, can exist in four stereoisomeric forms, three of which have previously been discovered in nature. The missing stereoisomer, (+)-epi-α-bisabolol, was isolated from the essential oil of ..

,Studies on the Composition of Essential Oils of ‘Cineolic Eucalyptus’, hydrodistillation were investigated. The results obtained by gas chromatography showed typical finger-prints although the content of the main constituent, 1.8-cineole, was similar. Characteristic data of the samples studied are given.

YoungMin Kwon,Kirill Mechitov,Gul AghaA series of enantiomerically pure monocyclic monosubstituted γ-lactones was synthesized starting from optically active glutamic acid. The enantiomeric composition was examined by .H-NMR spectroscopy using the chiral solvation reagent [(R)-(-)-2,2,2-trifluoro-1-(9-anthryl)ethanol].
