The volatile composition of six Hypericum species has been studied. The essential oils were obtained by steam distillation in 500 mL H 2 O for 2 h in a modified Clevenger apparatus with a water-cooled oil receiver to reduce hydrodistillation over-heating artifacts, and their analyses were performed by GC and GC–MS. Identification of the substances was made by comparison of mass spectra and retention indices with literature records. A total of 100 different compounds were identified. The main constituents of the investigated populations of each taxon have been revealed as follows: Hypericum alpinum : (−)-β-pinene, γ-terpinene, (−)-( E )-caryophyllene; Hypericum barbatum : (−)-α-pinene, (−)-β-pinene, (−)-limonene, (−)-( E )-caryophyllene, (−)-caryophyllene oxide; Hypericum rumeliacum : (−)-α-pinene, (−)-β-pinene, (−)-limonene, Hypericum hirsutum : nonane, undecane, (−)-( E )-caryophyllene, (−)-caryophyllene oxide; Hypericum maculatum : spathulenol, globulol; Hypericum perforatum : (−)-α-pinene, ( Z )-β-farnesene, germacrene D; Monoterpene hydrocarbons were shown to be the main group of the taxa belonging to the section Drosocarpium, while the taxa of section Hypericum were more rich in sesquiterpene hydrocarbons.
