“…They are commonly known as “gum trees” because of the distinct and pleasant volatile exudate that is produced in response to a tissue breach. Many species have attracted global attention as a source for fragrance oils, biofuels, a fast-growing wood source and other commercial applications 43 .…”

A high throughput method for species identification and classification through chemometric processing of direct analysis in real time (DART) mass spectrometry-derived fingerprint signatures has been developed. The method entails introduction of samples to the open air space between the DART ion source and the mass spectrometer inlet, with the entire observed mass spectral fingerprint subjected to unsupervised hierarchical clustering processing. A range of both polar and non-polar chemotypes are instantaneously detected. The result is identification and species level classification based on the entire DART-MS spectrum. Here, we illustrate how the method can be used to: (1) distinguish between endangered woods regulated by the Convention for the International Trade of Endangered Flora and Fauna (CITES) treaty; (2) assess the origin and by extension the properties of biodiesel feedstocks; (3) determine insect species from analysis of puparial casings; (4) distinguish between psychoactive plants products; and (5) differentiate between Eucalyptus species. An advantage of the hierarchical clustering approach to processing of the DART-MS derived fingerprint is that it shows both similarities and differences between species based on their chemotypes. Furthermore, full knowledge of the identities of the constituents contained within the small molecule profile of analyzed samples is not required.

“…Typical descriptions for such oils are: “ Eucalyptus oil China 80%”, “ Eucalyptus oil 70/75% Spain/Portugal” and “ Eucalyptus oil 80/85% Spain/Portugal”. The highest price is associated with an essential oil know as ‘eucalyptol’ which contains about 98% 1,8-cineole [45,216]. In Table 7 the main Eucalyptus species that have been used for the extraction of medicinal essential oils are listed [217,218].…”

Chemical Variability and Biological Activities of Eucalyptus spp. Essential Oils

Many plant species produce mixtures of odorous and volatile compounds known as essential oils (EOs). These mixtures play important roles in Nature and have been utilized by mankind for different purposes, such as pharmaceuticals, agrochemicals, aromatherapy, and food flavorants. There are more than 3000 EOs reported in the literature, with approximately 300 in commercial use, including the EOs from Eucalyptus species. Most EOs from Eucalyptus species are rich in monoterpenes and many have found applications in pharmaceuticals, agrochemicals, food flavorants, and perfumes. Such applications are related to their diverse biological and organoleptic properties. In this study, we review the latest information concerning the chemical composition and biological activities of EOs from different species of Eucalyptus. Among the 900 species and subspecies of the Eucalyptus genus, we examined 68 species. The studies associated with these species were conducted in 27 countries. We have focused on the antimicrobial, acaricidal, insecticidal and herbicidal activities, hoping that such information will contribute to the development of research in this field. It is also intended that the information described in this study can be useful in the rationalization of the use of Eucalyptus EOs as components for pharmaceutical and agrochemical applications as well as food preservatives and flavorants.

“…The value of eucalyptus oil for medicinal purposes, and therefore the major determinant of its market price, is based largely on its cineole content, although physical characteristics such as colour, specific gravity and optical rotation may also be important for non-medicinal uses (see Doran, 1991). National and international standards exist which specify the minimum cineole content of pharmaceutical grade eucalyptus oil to be 70% (v/v;Coppen, 2002). These standards also set strict limits on the content of the undesirable eucalyptus oil components phellandrene and isovaleraldehyde which must be negligible (see Warren, 1991).…”

“…Lower production costs particularly in China, and to a lesser extent in Portugal and Spain, have resulted in species with inferior oil and cineole yields to blue mallee such as Eucalyptus globulus, E. smithii and E. dives, being planted and non-mechanically harvested on much larger scales (Warren, 1991;Coppen, 2002). Nevertheless, the overall superiority of blue mallee as a commercial source of cineole-rich eucalyptus oil makes the species an attractive candidate for improved selection strategies and plantation development in Australia.…”
