Compounds were identified by comparing the retention
indices of the peaks on BP-1 column with literature values,
computer matching against the library spectra built
up using pure substances and components of known
essential oils, and finally confirmed by comparison of
mass spectra of peaks with published data. Relative
amounts of individual components are based on
peak areas obtained without FID response factor correction.
The retention indices were obtained from gas chromatograms
by logarithmic interpolation between bracketing
n-alkanes. The homologous series of n-alkanes
(C-8 to C22; Poly Science Inc., Niles USA) were used
as standards.
