“…In 1987, Holeman and coworkers [ 25 ] found an E. bosistoana EO with a different chemotype, in which α-terpineol was the main component. Bouzabata and coworkers [ 26 ] also studied the composition and the chemical variability of eight EOs of E. bosistoana from Algerian Sahara, dividing the samples in two groups: in the first group, p-cymene was the dominant component; in the second group, as in sample here reported, high percentages of eucalyptol, ranging between 55.3 and 63.9%, were present. E. bosistoana and E. melliodora EOs, distilled from plants growing in Morocco region, had a chemical composition similar to our samples [ 27 ].…”

The complex taxonomy of Eucalyptus genus, the renewed interest in natural compounds able to combat microbial strains, the overuse of synthetic pesticides, the consequent request for alternative control methods were the reasons for this research. The essential oils (Eos) of Eucalyptus bosistoana, Eucalyptus melliodora, Eucalyptus odorata, Eucalyptus paniculata, Eucalyptus salmonopholia, and Eucalyptus transcontinentalis were analyzed by GC/MS and their potential phytotoxic activity was evaluated against the germination and radicle elongation of Sinapis arvensis, Raphanus sativus and Lolium multiflorum. The antibiofilm activity was assayed against both Gram-positive (Staphylococcus aureus and Listeria monocytogenes) and Gram-negative (Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter baumannii) bacteria. Monoterpenoids were the most representative constituents in all EOs and eucalyptol was the dominant component except in E. melliodora EO, in which p-cymene was the most abundant. In phytotoxic assays, the EOs from E. odorata and E. paniculata were the most active against germination and radical elongation of the tested seeds. Finally, the Eucalyptus EOs proved their capacity to effectively inhibit the adhesion process of all five pathogen strains, with percentages often reaching and exceeding 90%. These Eucalytpus EOs could have possible employments in the food, health and agricultural fields.

“…Finally, 1 μL of the sample was injected into a GC–MS for fatty acid analysis. Using this method, non-esterified fatty acids were obtained [ 49 ]. The identification of FAMEs was assisted by National Institute of Standards and Technology Library (NIST 17 version 2.3) and was confirmed manually.…”

“…This may be attributed to many factors including the probability of many adduct formations which were not completely identified due to the large error values calculated in relation to the literature. (R)-cryptone, input m/z 139.1228 and exact m/z 139.1117 therefore error m/z 0.0111, is known to be found in the higher plant Eucalyptus bosistoana [49] and has never been reported before as a component metabolite of C. vulgaris in the literature. Hence further research is ongoing to establish more facts regarding its identification in C. vulgaris.…”

Comprehensive GCMS and LC-MS/MS Metabolite Profiling of Chlorella vulgaris

et al. 2020

The commercial cultivation of microalgae began in the 1960s and Chlorella was one of the first target organisms. The species has long been considered a potential source of renewable energy, an alternative for phytoremediation, and more recently, as a growth and immune stimulant. However, Chlorella vulgaris, which is one of the most studied microalga, has never been comprehensively profiled chemically. In the present study, comprehensive profiling of the Chlorella vulgaris metabolome grown under normal culture conditions was carried out, employing tandem LC-MS/MS to profile the ethanolic extract and GC-MS for fatty acid analysis. The fatty acid profile of C. vulgaris was shown to be rich in omega-6, -7, -9, and -13 fatty acids, with omega-6 being the highest, representing more than sixty percent (>60%) of the total fatty acids. This is a clear indication that this species of Chlorella could serve as a good source of nutrition when incorporated in diets. The profile also showed that the main fatty acid composition was that of C16-C18 (>92%), suggesting that it might be a potential candidate for biodiesel production. LC-MS/MS analysis revealed carotenoid constituents comprising violaxanthin, neoxanthin, lutein, β-carotene, vulgaxanthin I, astaxanthin, and antheraxanthin, along with other pigments such as the chlorophylls. In addition to these, amino acids, vitamins, and simple sugars were also profiled, and through mass spectrometry-based molecular networking, 48 phospholipids were putatively identified.

“…Compositions of the major component of EO have been reported differently. Ben Hassine et al found α-pinene and 1,8-cineol as major components (Ben Hassine et al, 2012), and Bouzabata et al (2014) found mainly α-and β-pinene. Whatever, EO extract is able to implement the innate cell-mediated immune response besides its anti-septic properties.…”

Eucalyptus oil (EO), an essential oil isolated from Eucalyptus leaves, was examined for its effect on lipopolysaccharide (LPS) and Klebsiella pneumoniae-induced COPD in rats. The COPD model was induced by instilling intratracheally with LPS and K. pneumoniae. The test compound, EO (30, 100 and 300 mg/kg), prednisone acetate (10 mg/kg) or vehicle was instilled intragastrically after three weeks exposure to LPS and K. pneumoniae, lasting for 4 weeks. EO significantly reduced amounts of inflammatory cells in bronchoalveolar lavage fluid (BALF) and blood, and decreased bronchiolitis, emphysematous changes and thickness of bronchioles. It also significantly reduced the increased AB-PAS-positive goblet cells in bronchioles. Prednisone acetate attenuated pulmonary inflammation and airway mucus hypersecretion, but no significant difference was found on emphysema. Pretreatment with EO markly reduced the production of proinflammatory cytokines TNF-α and IL-β in lung homogenate, significantly decreased the elevated malondialdehyde (MDA) level and and increased superoxide dismutase (SOD) activity. These findings indicate that EO could exert an protective effect against LPS plus K. pneumoniae-induced lung indury via inhibition of proinflammatory cytokines production and improvement of anti-oxidant status. The results provide evidence that EO might have its potential to be a proper candidate drug in the treatment of COPD.
