Abstract

With respect to the influence of extraction method on the oil yield and essential oil composition, we examined three common methods of extraction (i.e. water and steam distillation, hydrodistillation and steam distillation) on the oil yield and essential oil composition of Eucalyptus camaldulensis Dehn from Iran. The oils were produced at the yields of 0.22,0.60 and 0.60% (based on fresh weights), respectively. The essential oils were then analysed by GC and GC/MS. Twenty-two compounds were identified which among them 1,8-cineole (63.7,48.8,35.6%), P cymene(15.2,16.3,21.3%), spathulenol (3.9,3.7,6.7%) and y-terpinene (5.1,2.3,2.5%) were the major constituents, respectively.
