Intense studies on Genus Eucalyptus essential oil composition have been published already (Nair et al, 2008; Gamal and Sabrin, 2007; Batista-Pereira et al, 2006; Sartorelli et al, 2006; Hedges and Wilkins, 1991; Bignell et al, 1998).

The genus Eucalyptus, comprised of over 700 different species, include some of the fastest growing woody plants in the world and, at approximately 18 million hectares in 90 countries, it is one of the most widely planted genus of plantation forest trees in the world.
One of these medicinal plants, many species of the genus Eucalyptus from the Myrtaceae family are used in many parts of the world for the treatment of a wide variety of diseases including microbial infections (Ben Arfa et al, 2007).
The essential oil constituents of the genus Eucalyptus (Myrtaceae) have been well characterized (Batista-Pereira et al, 2006) Eucalyptus species produce numerous volatile compounds in large amounts, especially isoprenoids (here referred to as terpenes), which are accumulated in glands abundantly distributed throughout the leaf parenchyma and bark.
