Paolini J., Dessi M-A., Bernardini A-F., Costa J The composition of the essential oils of T. chamaedrys L. from Corsica and Sardinia islands were investigated using a combination of gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS) after fractionation over column chromatography. Eighty seven compounds were identified, the main components were (E)--caryophyllene (29.0 % and 27.4 %, respectively) and germacrene D (19.4 % and 13.5 %, respectively), followed by -humulene (6.8 %) and -cadinene (5.4 %) in the Corsican sample and by caryophyllene oxide (12.3 %) and -humulene (6.5 %) in the Sardinian sample. The study confirms the quantitative variability of the chemical composition of T. chamaedrys essential oils.
