A population of 52 genotypes of Myrtle (Myrtus communis L.), selected in the framework of a domestication program and growing in the same collection field at Oristano (Central Western Sardinia, 39°54′ N 8°35′ E), was analyzed by GC/MS for leaf essential oil composition. The chemical composition of essential oils was quite variable with a number of compounds ranging from 31 to 78 depending on cultivar. One hundred and eighteen compounds were globally identified in the various genotypes. However, α-pinene, limonene, 1,8-cineole, α-terpineol, and linalool always resulted as main components with few differences among samples. Minor compounds have been the determining factors in differentiating or associating genotypes in the outputs of a principal component analysis (PCA), where the results of another analysis of fruit essential oils of the same genotypes were also jointly used. Genotypes were discriminated according to mother plant characterization or ecological variables, such as site altitude, soil nature, and presence or absence of calcareous soils in the substrate of the localities of origin.

Pharmacological Potential

Mechanical damage, during grafting, results in the formation of reactive oxygen species, which are neutralized by the enzymatic and non-enzymatic antioxidant systems which may influence the essential oil composition of grafts and rootstocks because of the formation of oxygenated terpenes, substances with higher reactivity against pathogens. Various studies have demonstrated the biological activity of Annonaceae and the important pharmacological potential of the substances produced by the genus Annona. Thus, we studied the essential oils of leaves collected from the graft (Annona × atemoya) and lateral budding from the rootstock (Annona emarginata), in the same individual, in order to characterize chemical profile. The extraction was carried out by hydrodistillation and separation, quantification and identification of the substances were performed by gas chromatography coupled to a mass spectrometer. Chemical profiles of essential oils were evaluated by principal component analysis (PCA). Annona × atemoya and Annona emarginata presented chemical profiles of essential oil with specific substances. Some substances are common in oils of both species. Germacrene D is predominant in Annona × atemoya and α and β-selinene, β-elemene and spathulenol occurred in Annona emarginata. Our results suggest that the profile of such essential oil may be another indicator for the success of the combination of these two species.

The main objective of this study was to analyze and identify the essential oil composition of S. officinalis populations growing in Republic of Macedonia and to evaluate these data according to different standards’ requirements for, commercially most utilized, Dalmatian sage. The essential oil yield, obtained after hydrodestilation from leaves, of three different populations of Salvia officinalis L. from Republic of Macedonia was determined, varying from 1.40 to 3.46%. The GC/FID/MS analysis of the composition of the essential oils revealed 63, 57 and 51 components in Galicica Mtn., Jablanica Mtn. and Karaorman Mtn. sage populations, respectively. The main components of the oil, in all three samples, were the terpene hydrocarbons, encompassing the monoterpenes: camphor (13.15 - 25.91%), α-thujone (19.25 - 26.33%), β-thujone (2.03 - 5.28%), 1,8-cineole (6.51 – 13.60%), α-pinene (0.93 – 1.47%), borneol (1.07 – 4.67%), then sesquiterpenes: trans (E)-caryophyllene (1.72 – 5.33%), α-humulene (2.89 – 7.99%), viridiflorol (4.27 – 7.99%), and the diterpene manool (2.13 - 3.79%). Thus, our results for the essential oil composition of sage complied with the reference values specified in the DAC 86 monograph for Salvia essential oil.

The seasonal variation in the chemical composition of the leaf essential oil of Zanthoxylum clava-herculis has been analyzed by GC-MS. Three individual trees were sampled four times during the course of the 2004 growing season. Notable differences were recorded in the essential oil yields from the three trees on the four collection dates; yields were highest in May and lowest in July The leaf essential oils were made up of 25 components, largely menthane monoterpenoids, dominated by limonene (44-73%) and 1,8-cineole (16-43%), with lesser amounts of α-thujene, linalool, γ-terpinene, and α-terpineol. The ratio of oxygenated monoterpenoids to monoterpene hydrocarbons generally increased during the season, largely reflected in the 1,8-cineole/limonene ratio.

The Myrtus communis L. leaves samples were collected from five locations of its native grownareas in Lattakia, Syria, during their blooming seasons (June, 2009). Essential oil (EO) extraction wascarried out by hydro-distillation in a Clevenger apparatus. The EO was analysed by both gas chromatography-Flame Ionization Detector (GC-FID) and gas chromatography/mass (GC/MS) techniques. The EO yieldof the dry samples was found to be around 1.88%. The main identified components of EO were: µ-pinene30.40%, 1,8-cineole 17.66%, limonene 8.96%, myrtenol 5.78%, and b-caryophyllene 5.00%. The bulk EOand the separated components were tested for their antibacterial activities against Escherichia coli O157,Salmonella typhimurium, Klebsiella pneumoniae, Yersinia enterocolitica O9, Brucella melitensis, Proteusspp., and Pseudomonas aeruginosa by using broth micro-dilution method. It was found that citronellal andnerol were the most effective components against all pathogens.
