In this research, extraction of essential oil from dry Citrus Limon (Lisbon and Eureka varieties) peel was performed by hydrodistillation (HD) method and extraction yield, extraction time, chemical composition of essential oils, physical constants, energy consumption, and quantities of released carbon dioxides in the atmosphere were investigated. Essential oil yield of Lisbon and Eureka varieties were 1.22±0.14 and 1.18±0.14% (w/w), respectively. There were no significant differences among physical constants (refractive index, color, and specific gravity) of extracted essential oils from Lisbon and Eureka varieties of lemon peel. Also, there were no significant differences among extraction energy consumption of both Lisbon and Eureka varieties (0.67 kWh). Using GC/MS apparatus, components of extracted essential oils were identified. The major component of extracted essential oils from Lisbon and Eureka varieties was limonene (66.24±4.69 and 59.40±4.20%, respectively). Also, there were no significant differences between quantity and quality of major components of extracted essential oils from two C. Limon varieties.
