COMPOSITION OF ESSENTIAL OIL FROM LEAVES OF EUCALYPTUS DELEGATENSIS

Article abstract of DOI:10.1016/S0031-9422(00)84946-8

The major components of a dichloromethane extract of mature Eucalyptus delegatensis leaves were cis- and trans-p-2-menthen-1-ol, trans-piperitol, α- and β-eudesmol, 4-phenyl-2-butanone and methyl cinnamate.The major terpenoid was considered to be trans-piperitol, which was responsible for the peppermint aroma of freshly crushed leaves.The steam distillate of the same leaves contained the above compounds together with a number of monoterpene hydrocarbons which were considered to be artefacts.Use of these hydrocarbons as chemotaxonomic markers was considered to be erroneous.Key Word Index-Eucalyptus delegatensis; Myrtaceae; alpine ash; essential oil; cis- and trans-p-2-menthen-1-ol; trans-piperitol; monoterpenoids; sesquiterpenoids; phenylpropanoids; peppermint aroma; chemotaxonomy.
