“…In this study α-pinene and β-pinene was found in E. grandis and E. torelliana as the major components. As shown in Table 3 and Table 4, the main constituents of E. grandis and E. torelliana essential oils were similar to that of the same species investigated respectively by Dagne et al from Ethiopia [19], Loumouamou et al from CongoBrazzaville [17]. In Table 3, α-pinene is one the main components who is present in the samples from Brazil (40%, 55%; 24%, 7%), Morocco (14%, 64%), Nigeria (30%, 4%) and Ethiopia (44%, 7%).…”

“…From Congo-Brazzaville Loumouamou et al have reported a very rich α-pinene (78%, 1%) sample of E. torelliana [16]. From Brazilian Cerrado the major components of the oil of E. grandis are p-cymene (14%, 5%), isoleptopermone (13%, 2%) 1,8-cineole (5%, 5%) [17]. Jeane Silva et al have reported an analgesic and anti-inflammatory effects of a Brazilian sample of E. grandis essential oil rich in monoterpenic hydrocarbons (α-pinene, γ-terpinene), p-cymene) [12].…”

“…The major components of E. grandis and E. urophylla oils from Ethiopia were respectively α-pinene (44%, 7%), α-pinene (30%, 5%) and, limonene (9%, 8%), β-pinene (9%, 1%) [19]. The Brazilian Cerrado E. urophylla essential oil contained 1,8-cineole (44%, 7%), α-pinene (15%, 6%), α-terpenyl acetate (11%, 7%) [17] Cimanga et al have reported the chemical composition of the essential oils of E. deglupta and E. urophylla from the Democratic Republic of Congo. The major components of E. deglupta and E. urophylla are respectively 1,8-cineole (35%, 7%), cryptone (25%, 4%) and 1,8-cineole (57%, 7%), α-pinene (10%, 1%) [11].…”

The chemical composition of the essential oils obtained from the dried leaves of five species of the genus Eucalyptus (E. camaldulensis, E. deglupta, E. grandis, E. torelliana, E. urophylla) growing in Côte d'Ivoire, was analyzed by means of GC and GC/MS. The density and the refractive index were measured. The major components of all these oils are: α-pinene, β-pinene, α-phellandrene, limonene, γ-terpinene, p-cymene and β-caryophyllene. The particularity of these oils is their monoterpene hydrocarbons major components.

BackgroundTerpenoids are abundant in the foliage of Eucalyptus, providing the characteristic smell as well as being valuable economically and influencing ecological interactions. Quantitative and qualitative inter- and intra- specific variation of terpenes is common in eucalypts.ResultsThe genome sequences of Eucalyptus grandis and E. globulus were mined for terpene synthase genes (TPS) and compared to other plant species. We investigated the relative expression of TPS in seven plant tissues and functionally characterized five TPS genes from E. grandis. Compared to other sequenced plant genomes, Eucalyptus grandis has the largest number of putative functional TPS genes of any sequenced plant. We discovered 113 and 106 putative functional TPS genes in E. grandis and E. globulus, respectively. All but one TPS from E. grandis were expressed in at least one of seven plant tissues examined. Genomic clusters of up to 20 genes were identified. Many TPS are expressed in tissues other than leaves which invites a re-evaluation of the function of terpenes in Eucalyptus.ConclusionsOur data indicate that terpenes in Eucalyptus may play a wider role in biotic and abiotic interactions than previously thought. Tissue specific expression is common and the possibility of stress induction needs further investigation. Phylogenetic comparison of the two investigated Eucalyptus species gives insight about recent evolution of different clades within the TPS gene family. While the majority of TPS genes occur in orthologous pairs some clades show evidence of recent gene duplication, as well as loss of function.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-015-1598-x) contains supplementary material, which is available to authorized users.
