Volatile Oil Constituents of the Eucalyptus viridis R. T. Baker and Eucalyptus oleosa F. Muell. Leaves from Iran

The genus eucalyptus (family myrtaceae) comprises well-known plants ofover 600 species of trees. although most of the plants are native to australia, numerousspecies have been introduced to other parts of the world, including iran, as economic andornamental trees in forest trial provenances, where the plants have become source ofimportant fast-growing hardwood trees and eucalyptus oils.objective: aim of this studu is to determine chemical composition in essential oils ofeucalyptus for medicinal uses.methods: the essential oils isolated by hydrodistillation from the leaves of twoeucalyptus viridis r. baker and eucalyptus oleosa f. muell. were analysed by gc andgc/ms.results: the main components identified in e. viridis oil were 1,8-cineole (84.7%), -pinene (4.4%), trans-pinocarveol (2.2%) and in e. oleosa were 1,8-cineole (89.4%), â-pinene (1.2%) and - pinene (1%).conclusion: the chemical composition of the oils with high content of 1,8-cineole (84.7and 89.4%) are classified as a “eucalyptol or medicinal” type.
