Belhachemi, Asma published the artcileGC-MS and GC-FID analyses of the essential oil of Eucalyptus camaldulensis grown under greenhouses differentiated by the LDPE cover-films, Recommanded Product: cis-3,7-Dimethyl-2,6-Octadien-1-Ol, the publication is Industrial Crops and Products (2022), 114606, database is CAplus.
The chem. composition of essential oils (EOs) can vary from one plant to another of the same species and can be affected by several factors including the environment of growth. The research was carried out on the EOs of Eucalyptus camaldulensis leaves grown in three sep. greenhouses differentiated by their low-d. polyethylene (LDPE) covering material. This study aimed to compare the impact of the type of the greenhouse cover film on the internal microclimate, light intensity, and chem. composition of E. camaldulensis EOs. Eucalyptus species was initially cultivated from the seeds and the EOs were extracted from the leaves of 14 wk aged trees. The extraction was performed by hydrodistillation using a Clevenger-type apparatus Qual. and quant. analyses of the extracted EOs were performed using gas chromatog. coupled with mass spectrometry (GC-MS) and gas chromatog. coupled with a flame ionization detector (GC-FID). The analyzed samples were rich in terpenes with a total of 66 identified compounds The oxygenated monoterpenes pinocarvone and -carvone were only identified in the essential oils from multilayered greenhouses. cis-1-Methyl-4-(1-methylethyl-)-2-cyclohexen-1-ol was absent in eucalyptus EOs from the three-layer greenhouse, unlike the others that had it. Different compound contents were detected in the extracted essential oils, according to their greenhouse cover conditions. 1,8-Cineol was the compound present in a higher amount as expected, with the highest value of c.a 164.78 mg/gdw from the leaves of E. camaldulensis cultivated in the ordinary greenhouse. Contents of 51.55 mg/gdw and 42.11 mg/gdw were obtained from E. camaldulensis cultivated in the three-layers and monolayer greenhouses, resp. In contrast, the EOs of E. camaldulensis grown under the monolayer greenhouse presented the highest content of some aromadendranes family compounds This study shows that the greenhouse cover-film should be chosen thoughtfully because it plays a major function regarding its effect on the chem. composition of the EOs of E. camaldulensis cultivated in greenhouse environments.
