The direct qualification and quantitation of the
volatile organic components of four Eucalyptus camaldulensis
fruit samples, obtained from different geographical areas in
Turkey, is studied using a direct thermal desorption (DTD) technique
coupled with comprehensive two-dimensional gas chromatography
time-of-flight mass spectrometry. It is found that the E. camaldulensis
sample from Adrasan gave a slightly higher oil yield (1.18%)
than the others. The number of components quantitatively identified
from Adrasan, Belek, Kuyucak, and Cesme were 46, 54, 55, and
59, respectively. The main compounds found in the volatile oils
were: aromadendrene (6.45–15.02%), eucalyptol (0.17–12.61%),
g-gurjunene (8.40–10.08%), terpinolen (1.98–8.39%),
spathulenol (1.42–8.34%), a-pinene (0.85–6.81%),
ledene (0.94–6.72%), and longifonene (0.07–6.22%).
The composition of the volatiles desorbed from samples from all
four different areas varied qualitatively and quantitatively.
All identified compounds were quantitated using total ion chromatogram
peak areas. DTD is a good method for qualitative and/or quantitative
analysis of complex mixtures, and in particular for quantitative
analysis of plant samples, which can yield data without the traditional
obligation for costly and time consuming extraction techniques.
