“…A similar trend has also been demonstrated for several other plant species, mainly from the Apiaceae, including Foeniculum vulgare Mill., Laser tribolium L. or Prangos uloptera DC [ 45 , 46 , 47 ], but also from the Lamiaceae, such as Stachys schtschegleevi Sosn. [ 48 ].…”

Chemical Composition, Antioxidant and Anti-Inflammatory Activities of Clary Sage and Coriander Essential Oils Produced on Polluted and Amended Soils-Phytomanagement Approach

et al. 2021

The potential of essential oils (EO), distilled from two aromatic plants—clary sage (Salvia sclarea L.) and coriander (Coriandrum sativum L.)—in view of applications as natural therapeutic agents was evaluated in vitro. These two were cultivated on a trace element (TE)-polluted soil, as part of a phytomanagement approach, with the addition of a mycorrhizal inoculant, evaluated for its contribution regarding plant establishment, growth, and biomass production. The evaluation of EO as an antioxidant and anti-inflammatory, with considerations regarding the potential influence of the TE-pollution and of the mycorrhizal inoculation on the EO chemical compositions, were the key focuses. Besides, to overcome EO bioavailability and target accession issues, the encapsulation of EO in β-cyclodextrin (β-CD) was also assessed. Firstly, clary sage EO was characterized by high proportions of linalyl acetate (51–63%) and linalool (10–17%), coriander seeds EO by a high proportion of linalool (75–83%) and lesser relative amounts of γ-terpinene (6–9%) and α-pinene (3–5%) and coriander aerial parts EO by 2-decenal (38–51%) and linalool (22–39%). EO chemical compositions were unaffected by both soil pollution and mycorrhizal inoculation. Of the three tested EO, the one from aerial parts of coriander displayed the most significant biological effects, especially regarding anti-inflammatory potential. Furthermore, all tested EO exerted promising antioxidant effects (IC50 values ranging from 9 to 38 g L−1). However, EO encapsulation in β-CD did not show a significant improvement of EO biological properties in these experimental conditions. These findings suggest that marginal lands polluted by TE could be used for the production of EO displaying faithful chemical compositions and valuable biological activities, with a non-food perspective.

Myrtle (Myrtus communis L.) is an important medicinal plant, of which all parts have pharmaceutical and nutritional applications and which is distributed throughout the southwest regions of Iran. The aerial parts of myrtle were collected at different phenological stages (vegetative, flowering, unripe fruit and ripening fruit stages, after the fully mature fruit dispersal stage) from Fars Province of Iran and were analyzed with GC–FID and GC–MS. All the data were submitted to multivariate statistical analysis, showing many differences among the various plant parts and their phenological stages. Monoterpene hydrocarbons (18.9–50.5%) and oxygenated monoterpenes (38.2–72.4%) were the most abundant class in the volatile emissions, with α-pinene, 1,8-cineole, limonene, linalool, α-terpineol, linalyl acetate and geranyl acetate being the main constituents in the majority of the examined samples. α-Pinene content ranged from 8.88% at the after fully mature fruit dispersal stage (leaves) to 32.84% at the flowering stage in the leaves. Limonene, which is the dominant component at the flowering stage, was 23.97% in the flowers, while the limonene amount was 0.14–1.42% at other harvest stages. The greatest 1,8-cineole amount was obtained prior to flowering, 45.98%, while the lowest amount was obtained at the flowering stage, in the flowers. The total phenol and flavonoid contents varied between different myrtle parts: the highest total phenol and flavonoid contents were obtained for the extract made of the before-flowering stage in leaves (66.52 mg GAE/g and 7.49 mg QE/g extracts). Overall, the study indicated that collecting myrtle at the vegetative and flowering stages, especially the leaves organs, would be of considerable importance.

“…EOs are secondary metabolic aromatic products derived from plant roots, stems, leaves and fruit and are volatile at room temperature. EOs inhibit the growth of some microorganisms [17] by disrupting cell membranes, causing cell death or inhibiting the sporulation and germination of food spoilage microbes [7]. Several lines of research support the efficacy of EOs as safe antimicrobial agents, and they can be used as an efficient strategy to control fruit pathogens instead of using chemicals with potential health and environmental consequences [18][19][20].…”

Microbial food spoilage has been a major source of concern because it widens the global food production-to-consumption gap. Thus, in the current study, we aimed to isolate, characterize and identify bacteria associated with spoiled apple fruit in Al-Ahsa city, Saudi Arabia. MDK33, a bacterial strain isolated from rotten apple fruit, was characterized at the phenotypic and genotypic levels. Furthermore, the antibacterial effect of oregano essential oil (OEO) against MDK33 was investigated. MDK33 formed circular colonies with entire margins, and the cells were Gram-negative rods with no endospores. Biochemical characterizations of MDK33, as revealed by the Biolog Gen III MicroPlate test system, indicated that the strain utilized 66 (~70%) of the 94 diverse metabolites and did not utilize 29 (~30%). MDK33 grew well on a variety of substrates, including pectin, gelatin, Tween 40 and dextrin, at pH 5 and 6; tolerated salts up to 4% NaCl; and was resistant to multiple antibiotics. Furthermore, based on the sequences of the 16S rRNA gene, MDK33 was identified as Serratia liquefaciens at a 99.73% identity level. Koch’s postulates were affirmed, confirming that S. liquefaciens MDK33 is the causative agent of apple rot disease in Al-Ahsa, Saudi Arabia. The minimum inhibitory concentration (MIC) of 0.23 mg/mL for oregano oil against S. liquefaciens MDK33 demonstrated remarkable antibacterial and antibiofilm activities. This is the first isolation of pathogenic S. liquefaciens as the causative agent of rot disease of apple fruit and its inhibition by oregano oil. Furthermore, the findings pave the way for oregano oil to be evaluated as a natural preservative to reduce post-harvest losses while maintaining high quality for sustainable food security in future studies.
