“…The EO from C. verum, as prevalently constituted by E-cinnamaldehyde, had a composition consistent with that previously described [28], while the composition of the EO from C. camphora resulted quite unusal for the high content of limonene along with eucalyptol, which instead characterizes some chemotypes of this species [29]. Plant EOs have been reported to have a large number of biological activities which are determined by their specific chemical composition.…”

In this study, the relationship between nematicidal activity and chemical composition of ten essential oils (EOs) from different plant species was investigated both in in vitro assays on juveniles (J2) and eggs of the root-knot nematode Meloidogyne incognita and in experiments on tomato in soil infested by M. incognita. Nematode J2 were exposed for 4, 8 or 24 h to 0.78–100 μg mL−1 concentrations of each EO, whereas 24, 48 or 96 h exposures to 250, 500 and 1000 μg mL−1 solutions were tested on M. incognita egg masses. Treatments with 50, 100 or 200 μg kg soil rates of each EO were applied in the experiment on potted tomato. The highest nematicidal potential resulted for the C. verum EO, as highly toxic to both M. incognitaJ2 and eggs and strongly suppressive on nematode multiplication on tomato roots. The infestation of M. incognita on tomato roots was also strongly reduced by the EOs from E. citriodora and S. aromaticum, both highly toxic to M. incognitaJ2 but less active on nematode eggs. Adversely, R. graveolens EO strongly inhibited the egg hatch but was limitedly toxic to the infective J2. Chemical composition of the EOs was determined by GC-FID and GC-MS. The ten EOs showed a very different chemical composition in terms of major phytochemicals, with one or two dominant components totally amounting up to 85%. The structure–activity relationship based on the main phytochemicals identified in the assayed EOs and their nematicidal effects on M. incognita was also discussed. Results from this study confirmed that the selection of suitable EO raw materials can lead to the formulation on new effective nematicidal products.

“…The large amount (approximately 40%) of 1,8-cineole determined by Scalvenzi et al [ 11 ] in this essential oil from samples collected in Pastaza contrasts with the 1.82% (highest percentage, compound 7) of this compound found in the Rich clay samples ( Table 2 ) of the present research. In similar studies, it was determined that eucalyptol (1,8-cineole) (53.49%) may be involved in the larvicidal activity of the Cinnamomum camphora essential oil against Anopheles stephensi [ 19 ] and that the essential oil from Eucalyptus nitens , in which 1,8-cineole is present in 22.88%, showed repellent and larvicidal activity against Aedes aegypti and Aedes albopictus [ 20 ]; in these studies, it is suggested that the repellent effect is not only due to the main component, but that it occurs in conjunction with other compounds.…”

Ocotea quixos (Lam.) Kosterm. is an aromatic tree native to Ecuador, whose leaves are used to prepare aromatic beverages to which different health benefits are attributed. In this study, Ocotea quixos leaves were collected in the Amazon region in different environmental conditions and subjected to hydrodistillation to isolate the essential oil. The collection variables used were type of soil, amount of shade, and height; in addition, the presence of twig and leaf age and moisture were used as variables. Chemical composition was analyzed by means of gas chromatography equipped with a flame ionization detector and gas chromatography coupled to mass spectrometry. A wide variety of chemical compositions were detected in the samples. In total, forty-seven compounds were identified, which represented between 97.17% and 99.89% of the total composition. The constituents were mainly grouped into aliphatic sesquiterpene hydrocarbons (33.03–55.89%), other compounds (8.94–47.83%), and oxygenated monoterpenes (1.97–39.66%). The main constituents were found to be (E)-cinnamyl acetate (5.96–41.65%), (E)-methyl cinnamate (0.38–37.91%), and trans-caryophyllene (8.77–37.02%). The statistical analysis suggested the existence of two essential oil chemotypes and a direct correlation between environmental conditions and chemical composition of the essential oils.

“…A total of 159 compounds with a similarity of more than 800 and a peak area of more than 0.02% were identified, accounting for 89.68% and 87.88% of the total essential oil from C. camphora fresh leaf and fallen leaf, respectively, as shown in Table 2 . To our knowledge, 109 of these compounds have not been previously identified in C. camphora leaf essential oil, mainly including δ-terpineol, (3-Methyl-oxiran-2-yl)-methanol, 3-heptanone, 2-[2-(ethenyloxy)ethoxy]-ethanol, formaldehyde, cis -sabinene hydrate, (+)-α-terpineol, 2-azido-2,3,3-trimethylbutane, ethanolamine, and (1-hydroxyethylidene)malonic acid diethyl ester [ 9 , 14 , 16 , 36 , 37 , 38 ].…”

Optimization and Characterization of Microwave-Assisted Hydro-Distillation Extraction of Essential Oils from Cinnamomum camphora Leaf and Recovery of Polyphenols from Extract Fluid

In this study, the efficiency of microwave-assisted hydro-distillation (MAHD) to extract essential oil from Cinnamomum camphora leaf, and the recovery of polyphenols from extract fluid were investigated. The effects of microwave power, liquid-to-material ratio, and extraction time on the extraction efficiency were studied by a single factor test as well as the response surface methodology (RSM) based on the central composite design method. The optimal extraction conditions were a microwave power of 786.27 W, liquid-to-material ratio of 7.47:1 mL/g, and extraction time of 35.57 min. The yield of essential oil was 3.26 ± 0.05% (w/w), and the recovery of polyphenols was 4.97 ± 0.02 mg gallic acid equivalent/g dry weight under the optimal conditions. Furthermore, the comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC×GC-TOFMS) was used to characterize the essential oils of fresh and fallen leaves, and 159 individual compounds were tentatively identified, accounting for more than 89.68 and 87.88% of the total contents, respectively. The main ingredients include sabinene, l-β-pinene, β-myrcene, α-terpineol, 3-heptanone, and β-thujene, as well as δ-terpineol and 3-heptanone, which were first identified in C. camphora essential oil. In conclusion, the MAHD method could extract essential oil from C. camphora with high efficiency, and the polyphenols could be obtained from the extract fluid at the same time, improving the utilization of C. camphora leaf.
