The essential oils (5 ml) were diluted with CH2Cl2
(495 ml) prior to analyses. GC/MS-analyses were performed
on a HP 6890 coupled with a HP 5972 MSD and
fitted with a Rtx-5MS 30m0.25mm capillarycolumn
(0.25 mm film thickness). The analytical conditions were:
carrier gas Helium, injector temperature 2501C, split
ratio 50:1, temperature program 60–2401C with 31C/
min. Components were identified bycompari ng their
Kovats retention indices (Adams, 1995) and mass
spectra (McLafferty, 1989). The results are given in
Table 1.
