“…For example, it has been reported that the chemical composition and yield of the essential oil of Mentha piperita var., grown under different agroecological locations in Egypt, vary significantly according to the climate conditions. Plants growing in high temperatures showed high menthone/menthol contents and high antioxidant activity that could be attributed to their high number of phenolic compounds and flavonoids compared to other locations [5].…”

e chemical composition of Aloe vera growing in the small town of San Andrés de Pica, an oasis of warm waters and typical fruits, located in Tamarugal province in the Northern Chilean region of Tarapacá is reported. e chemical characterization was performed using liquid chromatography (UHPLC) coupled to PDA and high-resolution mass spectrometry (HESI-Q-Orbitrap ® -MS) in four different plant parts of Aloe (peel, flowers, gel, and roots). Twenty-five phenolic compounds were identified, including cinnamic acids and other derivatives (e.g., caffeic and chlorogenic acids), chromones (e.g., aloesin and isoaloeresin D), anthracene compounds and derivatives (e.g., aloin A/B and emodin), and several C-flavonoids (e.g., orientin and isovitexin), among others. Total antioxidant activity of the ethanolic extracts of the peels, flowers, gel, and roots was measured as the capturing of the DPPH • and ABTS •+ radicals, while the iron-reducing antioxidant power (FRAP) was measured by spectroscopic methods. e peel had the highest antioxidant activity with values of 2.43 mM ET/g MF (DPPH • ), 34.32 mM ET/g MF (ABTS •+ ), and 3.82 mM ET/g MF (FRAP). According to our results, the peel is the best part of the plant for the production of nutraceuticals or cosmetics products for its greatest number of bioactive compounds. is is a new and innovative finding since the only part used in traditional medicine is the gel of Aloe, and the peel is generally considered waste and discarded.

“…Among plant secondary metabolites, essential oils (EOs), biosynthesized by glandular trichomes and other secretory structures in plants, are liquids particularly rich in volatile molecules such as monoterpene and sesquiterpene hydrocarbons, oxygenated monoterpenes and sesquiterpenes, esters, aldehydes, ketones, alcohols, phenols, and oxides [ 2 , 3 , 4 ]. The chemical composition of EOs can vary from plant to plant and even in the same species and depends on several factors such as post-harvest conservation conditions [ 5 ], extraction methods [ 6 , 7 , 8 ] and times [ 9 , 10 ], microclimate, and site in which the plant is growing [ 11 , 12 ]. EOs contribute to the plant relations with environment and with other organisms, and humans and animals take advantage of the abundance of such bioactive molecules from the plant kingdom [ 4 ].…”

Liquid and Vapor Phase of Four Conifer-Derived Essential Oils: Comparison of Chemical Compositions and Antimicrobial and Antioxidant Properties

et al. 2021

In this study, the chemical composition of the vapor and liquid phase of Pinus cembra L., Pinus mugo Turra, Picea abies L., and Abies Alba M. needles essential oils (EOs) was investigated by Headspace-Gas Chromatography/Mass Spectrometry (HS-GC/MS). In the examined EOs, a total of twenty-eight components were identified, most of which belong to the monoterpenes family. α-Pinene (16.6–44.0%), β-pinene (7.5–44.7%), limonene (9.5–32.5%), and γ-terpinene (0.3–19.7%) were the most abundant components of the liquid phase. Such major compounds were also detected in the vapor phase of all EOs, and α-pinene reached higher relative percentages than in the liquid phase. Then, both the liquid and vapor phases were evaluated in terms of antibacterial activity against three Gram-negative bacteria (Escherichia coli, Pseudomonas fluorescens, and Acinetobacter bohemicus) and two Gram-positive bacteria (Kocuria marina and Bacillus cereus) using a microwell dilution assay, disc diffusion assay, and vapor phase test. The lowest Minimum Inhibitory Concentration (MIC) (13.28 mg/mL) and Minimal Bactericidal Concentration (MBC) (26.56 mg/mL) values, which correspond to the highest antibacterial activities, were reported for P. abies EO against A. bohemicus and for A. alba EO against A. bohemicus and B. cereus. The vapor phase of all the tested EOs was more active than liquid phase, showing the inhibition halos from 41.00 ± 10.15 mm to 80.00 ± 0.00 mm for three bacterial strains (A. bohemicus, K. marina, and B. cereus). Furthermore, antioxidant activities were also investigated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis (3- ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assays, and a concentration-dependent antioxidant capacity for all EOs was found. P. mugo EO showed the best antioxidant activity than the other Pinaceae EOs. The four Pinaceae EOs could be further investigated for their promising antibacterial and antioxidant properties, and, in particular, α-pinene seems to have interesting possibilities for use as a novel natural antibacterial agent.

Morocco's prickly pear has high economic value. However, it’s infected by the cochineal Dactylopius opuntiae, causing massive losses. Thus, the present work aims to study insecticidal effect of bioactive natural extracts. Essential oils and hydrosols of oregano (Origanum vulgare), thyme (Thymus vulgaris), pennyroyal (Mentha pulegium) and peppermint (Mentha piperita) were tested. Two concentrations were used for essential oils (1.5% and 3%) and for hydrosols (100% and 75%) with contact and fumigant application. Mortality rate was determined after 24h of treatment. Highest values were recorded at 3% E.O concentration with contact assay comparing to fumigation. As it’s EO (99.44%), O. vulgare hydrosol has significant insecticidal activity reaching 80% of mortality rate. Chemical composition of essential oils using Gas Chromatography coupled to Mass Spectrometry (GC/MS) was studied. Bioactive compounds include carvacrol and m-cymene (O. vulgare and T. vulgaris), pulegone and l-menthone (M. pulegium) and Linalool and linalyl acetate (M. piperita). Data obtained relieved the importance of these plants as source of natural bioactive compounds against D. opuntiae.
