Composition of Tea Tree oil
The essential oil obtained from Tea Tree leaves (1 - 2% in fresh material) is composed of terpene hydrocarbons, mainly mono- and sesquiterpenes and their alcohols. In an analysis carried out on 800 samples of Tea Tree essential oil, about 100 different components were found, resulting in a great variability (with high frequency of chemotypes), the main one (>30%) being the terpinen-4-ol, a monocyclic monoterpene monocyclic alcohol. It also contains gamma- and alpha-terpinene, 1,8-cineole, terpinolene, p-cymene, alpha-pinene, alpha-terpineol and limonene, among other components.
The essential oil obtained from the Tea Tree is a colorless or slightly yellowish transparent liquid, insoluble in water and soluble in organic solvents, with a pleasant odor similar to turpentine.
In the European Pharmacopoeia (7.0 ed.) this essential oil (Melaleucae aetheroleum) is defined as "that obtained by steam distillation from the leaves and terminal branches of Melaleuca alternifolia (Maiden and Betch) Cheel". However, it is mostly obtained from the first species as recognized by the Australian Therapeutic Goods Administration.
The European Pharmacopoeia provides specific concentration ranges for the main components, with a minimum limit for terpinen-4-ol (greater than 30% and in accordance with the ISO/FDIS 4730: 2004 standards, required by the Australian standardization systems), a compound to which an important part of its activities is attributed, and maximum concentrations of others, such as 1,8-cineole, which must not be greater than 15% of the composition.
The chemotype marketed is terpinen-4-ol which must contain between 30 and 40% of that component.
