Essential Oils of Artemisia frigida Plants (Asteraceae): Conservatism and Lability of the Composition. PLANTS (BASEL, SWITZERLAND) 2023; 12:3422. [PMID: 37836162 PMCID: PMC10574723 DOI: 10.3390/plants12193422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 09/20/2023] [Accepted: 09/25/2023] [Indexed: 10/15/2023]
Abstract
Plants of arid regions have adapted to harsh environments during the long span of their evolution and have developed a set of features necessary for their survival in water-limited conditions. Artemisia frigida Willd. (Asteraceae) is a widely distributed species possessing significant cenotic value in steppe ecosystems due to its high frequency and abundance. This study examines different patterns of formation of essential oil composition in A. frigida plants under the influence of heterogeneous factors, including climate and its integral characteristics (HTC, Cextr, SPEI and others). The work is based on the results of our research conducted in Russia (Republic of Buryatia, Irkutsk region), Mongolia, and China, from 1998 to 2021. A total of 32 constant compounds have been identified in the essential oil of A. frigida throughout its habitat range in Eurasia, from Kazakhstan to Qinghai Province, China. Among them, camphor, 1,8-cineol and bornyl acetate are the dominant components, contained in 93-95% of the samples. Among the sesquiterpenoids, germacrene D is the dominant component in 67% of the samples. The largest variability within the composition of the essential oils of A. frigida is associated with significant differences in the climatic parameters when plants grow in high-altitude and extrazonal conditions.

Yaldiz G, Camlica M, Erdonmez D. Investigation of some basil genotypes in terms of their effect on bacterial communication system, and antimicrobial activity. Microb Pathog 2023; 182:106247. [PMID: 37453480 DOI: 10.1016/j.micpath.2023.106247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 07/06/2023] [Accepted: 07/07/2023] [Indexed: 07/18/2023]
Abstract
The exponential growth of multiresistant bacterial strains creates the need to explore new or combined strategies to combat bacterial resistance. Medicinal plant-derived compounds against pathogenic bacteria may provide new, simple approaches to developing more environmentally friendly antimicrobial agents. Many researchers focus on exploring novel or combined strategies for combating bacterial resistance. Aromatic plants containing essential oils, such as basil, are often used as therapeutic agents in the pharmaceutical industry. Recent research has shown that basil is effective against certain harmful food phytopathogenic bacteria and has antimicrobial and anti-quorum sensing properties, which were investigated in this study. Our results have shown that the essential oil and ethanol extract of basil exhibits both antibacterial activity and anti-quorum sensing activity against some Gram-negative and Gram-positive bacterial species. It has also been found to have antifungal effects on C. albicans. Among the tested microorganisms, the genotypes of PI 531396, PI 296390, PI 414199, PI 253157, PI 296391, PI 652071, midnight, and Dino cultivars have been found to be more effective than other genotypes. The highest effect on quorum sensing system was found in Moonlight and Dino cultivars, PI 296391, PI 414199, PI 652070, PI 172997 and PI 190100 genotypes. Dendrogram analysis has shown that there is a relationship between different genotypes depending on microorganisms and anti-quorum sensing activity. Ames 29184, PI 207498, and PI 379412 genotypes were in the same group. Biplot analyses were performed to determine the relationship between the studied properties, and the results showed that more than 47% of the total variation was in all forms.

Virucidal Activity of Lemon Essential Oil against Feline Calicivirus Used as Surrogate for Norovirus. Antibiotics (Basel) 2023; 12:antibiotics12020322. [PMID: 36830233 PMCID: PMC9952628 DOI: 10.3390/antibiotics12020322] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 01/27/2023] [Accepted: 02/01/2023] [Indexed: 02/05/2023] Open
Abstract
Norovirus (NoV) is regarded as a common cause of acute gastrointestinal illness worldwide in all age groups, with substantial morbidity across health care and community settings. The lack of in vitro cell culture systems for human NoV has prompted the use of cultivatable caliciviruses (such as feline calicivirus, FCV, or murine NoV) as surrogates for in vitro evaluation of antivirals. Essential oils (EOs) may represent a valid tool to counteract viral infections, particularly as food preservatives. In the present study, the virucidal efficacy of lemon EO (LEO) against FCV was assessed in vitro. The gas chromatography hyphenated with mass spectrometry (GC/MS) technique was used to reveal the chemical composition of LEO. The following small molecules were detected as major components of LEO: limonene (53%), β-pinene (14.5%), γ-terpinene (5.9%), citral (3.8%), α-pinene (2.4%), and β-thujene (1.94%). LEO at 302.0 μg/mL, exceeding the maximum non cytotoxic limit, significantly decreased viral titre of 0.75 log10 TCID50/50 μL after 8 h. Moreover, virucidal activity was tested using LEO at 3020.00 μg/mL, determining a reduction of viral titre as high as 1.25 log10 TCID50/50 μL after 8 h of time contact. These results open up perspectives for the development of alternative prophylaxis approaches for the control of NoV infection.

Abstract
In this study, five plant species, members of the Lamiaceae family, namely Salvia officinalis L., Salvia rosmarinus Spenn, Mentha × piperita L., Mentha spicata L. and Origanum vulgare subsp. hirtum (Link) Ietswaart, were studied for the influence of harvesting time on the herb crop yield, the volatile compounds (EOs) content/yield and their chemical composition. EOs were isolated by means of hydro-distillation from different plant parts at different growth stages. Their components were analyzed by gas chromatography coupled with mass spectrometry (GC-MS). The highest yields of EOs were obtained at the full flowering stage and important changes were observed in their composition. The fluctuations in the percentage composition of the major compounds in the EOs, throughout harvesting time, were observed at camphor/α-thujone for S. officinalis, camphor/1,8-cineole for S. rosmarinus, linalool/linalyl acetate and carvone/limonene for M. × piperita and M. spicata, respectively. The chemotype of O. vulgare subsp. hirtum was identified as carvacrol. The optimization of harvesting time could lead to increased crop production and better EOs quality control, with numerous industrial benefits upon the commercial production of such products.
