Analysis of Eucalyptus camaldulensis Volatiles from Turkey Using DTD-GC-MS

The direct analyses of the volatile organic components of 30 Eucalyptus camaldulensis fruit samples, obtained from the Antalya, Aegean and Cukurova regions in Turkey, was studied using a direct thermal desorption (DTD) technique coupled with gas chromatography mass spectrometry (GC-MS). It was found that the E. camaldulensis samples yielded a similar chemical composition. However, some of the compounds were only seen in one region, such as thymol in the Aegean region, ocimen and cis-sabinene hydrate in the Antalya region and nerolidol and pentacosane in the Cukurova region. A total of 68 components were identified from 30 samples. The main compounds found in the volatiles were: ledene (0-23.08 %), aromadendrene (0.59-42.31 %), alloaromadendrene (0-24.14%), globulol (0-19.97%) and isolongifolen (0-50.04 %). However, some of the quantities of the main compounds differed between samples. DTD with GC-MS is a good method for analysis of complex mixtures, and in particular for plant samples, which can yield data without the traditional obligation for costly and time consuming extraction techniques.
