Analysis of Eucalyptus camaldulensis Volatiles from Turkey Using

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
