“…Existen antecedentes que indican actividad pediculicida de compuestos volátiles de naturaleza terpénica y fenólica, usualmente concentrados en plantas aromáticas introducidas, pero que se encuentran dentro de productos de amplia distribución y comercialización nacional por su uso como especias 18 . Estos extractos han mostrado una acción comparable a grandes pediculicidas como el lindano, permetrinas y con acción larvicida, pero con baja toxicidad, vislumbrándose como tratamientos alternativos frente a parásitos que han adquirido resistencia frente a fármacos convencionales 19,20 .…”

“…Higher abundances of oxygenated terpenes seem to be associated to mature leaves in Eucalyptus species, Silvestre et al (1997) demonstrated that non-oxygenated terpenes were the major components in E. globulus young leaves, while oxygenated ones, particularly 1,8-cineole, were more associated to mature ones. Our results show that young leaves (from five-month seedlings) submitted to water deficiency at the end of nursery period developed a particular terpenoid blend, which seems to be more associated to mature leaves than to young ones.…”

“…Essential oil yield and chemical composition have shown significant variations between species corresponding to the same genus and even between individuals within a population of the same species (Nicole et al 1998;Chalchat et al 2000;Pagula et al 2000;Pappas and Sheppard-Hanger 2000). Leaf age is also a determining factor (Silvestre et al 1997;Wildy et al 2000), higher oil concentrations were found in E. camaldulensis when leaves were fully expanded, but not yet fully lignified (Doran and Bell 1994). Significant differences in essential oil yield and composition were detected between young and mature leaves from E. globulus (Chennoufi et al 1980;Silvestre et al 1997), and juvenile, mature, and senescent leaves of E. citriodora (Batish et al 2006a(Batish et al , 2006b.…”

Environmental factors contribute to modulate the level at which secondary metabolism occurs in plant species (Einhellig 1989), and in particular that related to biosynthesis of terpenic derivatives.…”

Water deficit, a common constraint in forestry, is the main cause of plant stress during plantation. The survival and growth of seedlings is also compromised by herbivory during establishment. The potential of nursery preconditioning to enhance survival chances of future trees by reducing palatability or attracting beneficial insects as a result of changes in chemical defences may be an answer to overcome this situation. Changes in essential oil production and composition were evaluated by GC and GC-MS in Eucalytus camaldulensis seedlings submitted to drought during four weeks at the last stage of nursery period (20 weeks). Significant changes in essential oil relative composition were found. Seedlings (young leaves) submitted to drought developed a terpenoid blend, which has been previously associated to mature leaves and related to their higher resistance towards herbivory. Total amount of non-oxygenated terpenes decreased by 44%, whereas some oxygenated sesquiterpenes (globulol, epiglobulol and ledol) were doubled, and 1,8-cineole content was enhanced by 28.3%.

“…For example, the EO of E. globulus from the municipality of Sobral in Brazil has been characterized by 1,8-cineole (83.89%), limonene (8.16%), and -pinene (4.15%) (Maciel et al, 2010), whereas in the central area of the Congo in Africa, the chemotype of eucalyptus EO was reported to be mostly 1,8-cineole (44.30%), with high amounts of camphene (23.10%) (Cimanga et al, 2002). However, E. globulus from Portugal contains 1,8-cineole (63.80%) and -pinene (14%) as the major compounds of its EO (Silvestre, Cavaleiro, Delmond, Filliatre, & Bourgeois, 1997).…”

The steam distillation-extracted essential oils (EOs) of three aromatic plants from the Kabylie region of Algeria (Eucalyptus globulus, Lavandula angustifolia, and Satureja hortensis) were analyzed by gas chromatography coupled with mass spectrometry (GC/MS). The primary compounds from these EOs were 1,8-cineole (81.70%) for Eucalyptus globulus, 1,8-cineole (37.80%) and -caryophyllene (20.90%) for Lavandula angustifolia, and carvacrol (46.10%), p-cymene (12.04%), and -terpinene (11.43%) for Satureja hortensis. To test the antibacterial properties of the EOs, agar diffusion and microdilution methods were used for Salmonella enterica serovar Enteritidis CECT 4300. The results revealed that all of the EOs possessed a significant anti-Salmonella activity. The inhibition diameters for Lavandula angustifolia and Eucalyptus globulus were 41.30 and 35.26 mm, respectively, whereas the essential oil (EO) of Satureja hortensis showed a stronger anti-Salmonella activity (51.15 mm) when compared to the two other EOs. The minimum inhibitory concentration values ranged from 1 to 8 μL/mL, and the MIC value of the Lavandula angustifolia EO was the lowest (1 μL/mL). Moreover, the anti-Salmonella activity of the EOs added at various concentrations to liquid whole eggs was investigated, and the results showed that the antibacterial effect is proportional to the quantity of EO added to the product. Based on the observed anti-Salmonella activity, the EOs tested are promising natural alternatives for the preservation of liquid whole eggs stored at 7 ± 1ºC to simulate Algerian refrigeration conditions.
