Abstract

<p><strong>Introduction:</strong> Eucalyptus has more than 400 species, while only a few species of this genus have been imported in Iran. In this study we aimed to investigate chemical compounds of the essential oils of Eucalyptus species adapted in Lorestan climate.</p> <p><strong>Methods:</strong> In this study, the fresh young leaves of four different Eucalyptus species including <em>E. suggrandis</em>, <em>E. globulus</em> subsp. <em>bicostata</em>, E. nitens and <em>E. globulus</em> subsp. <em>maidenii </em>were collected in spring (the middle of May) in khorramabad, Iran. The powder of air-dried leaves of different species of Eucalyptus was subjected to hydro-distillation using a Clevenger-type apparatus. The chemical compositions of different essential oils were detected using gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC/MS) and determination of their retention time (RT), retention index (RI) and Mass Spectra. The obtained data were analyzed using SPSS software.</p> <p><strong>Results: </strong>The results of this study indicated that there was significant difference (P&lt;0.01) among the yield and chemical compounds of the essential oils of studied species. The results showed that the yield of essential oil extracted from <em>E. suggrandis, E. globulus bicostata, E. nitens</em> and<em> E. globulus</em> <em>maidenii </em>were 1.12, 1.34, 2.57 and 5.38, respectively.</p> <p><strong>Conclusion: </strong>The essential oil constituents of four Eucalyptus species plant were different in among of some compounds. <em>E. globulus </em><em>maidenii&nbsp; &nbsp;</em>had most content of essential oil and 1.8-Cineole compound so it is necessary to identify quality and quantity characteristics of compounds available in this plant.</p>
