摘要:

The oils obtained by hydrodistillation and the headspace volatiles from the aerial parts ofHelichrysum italicumssp.serotinum(Boiss) andH. stoechasssp.stoechas(Moench) were analyzed by means of GC and GC/MS. Both oils were found to be dominated by non-oxygenated monoterpenes. A total of 68 compounds were identified. The major components ofH. italicumssp.serotinumwere guaiol (8.9%), nerol (7.0%) and β-caryophyllene (6.0%), while those ofH. stoechasssp.stoechaswere: α-pinene (28.3%), epi-α-bisabolol (21.9%) and β-caryophyllene (5.5%). Furthermore, the bacteriostatic activity of the oils against two Gram-positive and four Gram-negative bacteria was evaluated.
