Backhousia Myrtifolia Oil

#### Backhousia Myrtifolia. Essential oils are distilled from leaves and twigs of trees of the above name in southeastern Australia. It has been disclosed recently that at least 4 different "physiological" forms of this tree grow in the area. Consequently, it is scarcely economically feasible to produce the individual oils. Only experienced botanical experts can distinguish among the various forms just by looking at the trees. Other Australian trees, e.g. eucalyptus species, melaleuca species, occur in various physiological forms. So far, the most common types of essential oil distilled from the individual physiological forms are: - The **Elimicin**** **form of **Backhousia**** ****Myrtifolia**. The main constituent is trimethoxy-allylbenzene, a sweet-woody smelling material; - **Isoelemicin**** **form of **Backhousia**** ****Myrtifolia.**** **This oil consists mainly of Isoelemicin. - and 4): **Methyleugenol**** **form and Methyl **Isoeugenol**** **form. All four types of essential oil could be of considerable interest if they were produced on a large scale. They would be interesting starting materials for the isolation of the above mentioned main constituents which are either well-known and regularly used perfume materials (the latter two), or useful modifiers-fixatives for perfumes (the two former). None of the above four types of **Backhousia**** ****Myrtifolia**** ****Oil**** **are produced on a commercial scale.
