Considering the influence of extraction method on the oil yield and essentia! oil composition, we examined three common methods of extraction (i.e. Kaiser, Clevenger and steam distillation) on the oil yield and essential oil composition of Eucalyptus camaldulensis Dehn. from Iran. The oils were producted 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 separate limonene,Beta-phellandrene and 1,8-cineile. Twenty two compounds were identitied which among them 1,8-cineole (63.7, 48.8, 35.6%), p-cymene (15.2, 16.3, 21.3%), spathuienol (3.9, 3.7, 6.7%) and y-terpinene (5.1, 2.3, 2.5%) were the major constituents, respectively.
