title: Analysis of the essential oil composition from the different parts of Eryngiumglaciale Boiss. from Spain.
abstract: The essential oil from the different parts (inflorescences, stems + leaves and roots) of Eryngium glaciale Boiss. gathered in Sierra Nevada (Spain) has been extracted by steam distillation and analysed by gas chromatography and gas chromatography coupled to mass spectrometry. Quantitative but not qualitative differences have been found between the analysed parts. The principal compounds from the inflorescences oil were found to be phyllocladene isomer (43.5%), (E)-caryophyllene (15.2%) and valencene (11.5%), while the oil from stems and leaves only showed phyllocladene isomer (41.3%) as main one. The oil from the roots presented phyllocladene isomer (49.4%) and linalool (19.1%) as major constituents. This is the first report on the chemical composition of this species.
