ABSTRACT This study aimed to evaluate the chemical and antibacterial properties of the essential oil of B. dracunculifolia from three regions of Brazil: Midwest, Southeast and South region. The major compounds of essential oil from Midwest region were (E)-nerolidol (28.15%) and spathulenol (17.68%), both oxygenated sesquiterpenes. And the major compounds of essential oils from Southeast and South regions were (E)-nerolidol (12.75–13.95%), bicyclogermacrene (10.76–14.21%) and limonene (10.49–19.36%). The three essential oils showed antibacterial activity for both Gram-positive and Gram-negative bacteria tested, with MIC values from 0.03 to 0.15 mg/mL and MBC values from 0.05 to 0.30 mg/mL. The B. dracunculifolia essential oil from the Midwest region of Brazil presented higher values of oxygenated sesquiterpenes and was more effective on all tested bacterial strains, with lower and statistically significant MBC values, compared to the oils from the Southeast and South regions of Brazil

ABSTRACT A wild population of Thymus piperella L. was monitored for two years in order to correlate phenological stages and meteorological data with yield and, essential oil (EO) composition. The plant material was extracted by hydrodistillation and the EO was submitted to GC-MS and GC-FID analysis. To achieve reliable quantification, relative response factors were applied. The results showed a progressive increase in the proportion of carvacrol according to the sunlight duration and temperature increase, until reaching a maximum at the beginning of flowering stage (52.9 % and 41.0 % in 2018 and 2019, respectively). A simultaneous decrease was found in the amount of p-cymene (8.2 % and 12.8 % respectively) in the same stage, whereas -terpinene showed a similar evolution to that observed for carvacrol but with lower values (3.3 % - 14.6 %). From statistical analysis, significant changes in the relative proportions of carvacrol and its metabolic precursors: γ-terpinene and p-cymene were found. They have been explained based on the proposed metabolic pathways in the literature. On the other hand, when relating the changes in the EO profiles with rainfall data, a strong influence of the water supply on the evolution of the chemical composition was observed.

ABSTRACT Origanum onites L. (O. onites) is one of the cultivated Origanum species in Turkey. The aim of this study was to determine the cytotoxicity and cellular antioxidant effects of O. onites essential oil, carvacrol and p-cymene on HCT116 and HepG2 cells. O. onites essential oil components were analyzed by GC/MS and GC/FID. Cytotoxicity was analyzed via the MTT assay in HCT116 and HepG2 cells. Cellular antioxidant activities of O. onites essential oil, carvacrol and p-cymene were determined with DCFH-DA method. GC/MS analysis identified carvacrol (%78.4) as the main constituent of O. onites essential oil. 400 µg/ml concentration of O. onites essential oil, carvacrol and p-cymene were found to be active against HCT116 and HepG2 cells. Also, carvacrol showed higher cellular antioxidant activity than O. onites essential oil and p-cymene. We conclude that O. onites essential oil and carvacrol may be a candidate for pharmaceutical products in treatment of cancer.

ABSTRACT This study describes the chemical composition and the in vitro antifungal activity of the essential oil (EO) of Anvillea gracinii subsp. radiata aerial parts against three phytopathogenic using the poisoned food (PF) and the volatile assay (VA) techniques. Gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS) allowed the identification of 35 compounds which cis 8-acetoxychrysantenyl acetate (cis8ACA) (30.8%), cis-chrysanthenyl acetate (15.5%), 6-oxocyclonerolidol (14.9%) and τ-cadinol (7.4%) are the main constituents. In VA test, the minimum inhibitory concentrations (MIC) are 0.50 µL/mL for B. cinerea and P. expansum and 1.00 µL/mL for R. stolonifer, but they are 0.125 µL/mL for B. cinerea and 0.25 µL/mL for other fungi using PF technique. Molecular docking and molecular dynamics (MD) simulations revealed that cis8ACA has the smallest docking energy (-8.9 kcal.mol-1) indicating its high affinity to bind to the active site of the C14DM thereby forming a stable cis8ACA -C14DM complex.

ABSTRACT The chemical composition and biological activity of essential oils (EOs) from leaves of Origanum minutiflorum O. Schwarz & P.H.Davis, and seeds of Coriandrum sativum L. were investigated. Chemical analyses of EOs were performed and the major components were carvacrol (81.5%) and linalool (69.6%), respectively. The antimicrobial activity was assessed against several bacteria originating from the tonsillar tissue. Activities of EOs against Staphylococcus aureus biofilm were investigated, as well as the effect of the mixture of these EOs and antibiotics against the pathogen. The antioxidant activity of both EOs was determined by TBARS assay, and examined wild oregano EO showed better activity. Also, cytotoxicity of EOs was evaluated in vitro and both EOs showed potential to inhibit further proliferation of tumor cells. This study reported for the first time the effects of EOs on chronic tonsillitis causative pathogens, supporting their role as a natural bioactive therapeutic agent with possible antimicrobial applications.
摘要:研究了Origanum minutiflorum O.

ABSTRACT The aim of the presented work was to compare the efficiency of innovative (solvent-free microwave extraction, microwave-assisted hydrodistillation and supercritical CO2 extraction) extraction techniques vs. conventional Clevenger hydrodistillation of essential oil (EO) from poorly studied fennel rhizome. It was found that innovative extraction techniques enhance the EOs/extracts isolation, save time and exclude solvents providing green ecologically technologies. Solvent-free microwave extraction proved to be the most efficient with limonene and (E)-anethole as dominant compounds in concentration of 12.34 ± 0.31 and 35.63 ± 1.51 mg/ml, respectively, as well as with the largest number of isolated and identified compounds. Primary aroma compounds were identified by two direct headspace techniques – static headspace extraction (HSS) and headspace solid phase microextraction (HS-SPME) confirming limonene and (E)-anethole as dominant compounds in primary aroma mixture with 53.7 ± 2.02% and 30.9 ± 1.43% (HSS) and 69.8 ± 2.80% and 13.1 ± 0.11% (HS-SPME), respectively.

ABSTRACT Cinnamomum verum essential oil and its main component, cinnamaldehyde, were incorporated into nanoemulsions to improve their stability and activity. Oil-in-water (O/W) nanoemulsions were prepared using the high-energy ultra-sonication method. Cinnamon oil nanoemulsion exhibited a more vigorous DPPH radical scavenging activity (IC50 = 1.81 mg/L) than the standard α-tocopherol (IC50 = 9.16 mg/L). Cinnamaldehyde nanoemulsion exhibited the highest antibacterial action against Salmonella typhimurium and Staphylococcus aureus (MIC = 175 and 150 mg/L, respectively). It was also displayed the highest inhibition against Candida albicans (EC50 = 19.92 mg/L). Cinnamaldehyde nanoemulsion was the most active against mycelial growth of Aspergillus flavus and A. niger (EC50 = 38.20 and 134.80 mg/L, respectively). It also presented the highest activity against spore germination. This study describes antimicrobials and antioxidants based on nanoemulsions made from natural products that can be used to treat microbial infections.

ABSTRACT The aim of the present study was a chemical and chemometric analysis of Satureja kitaibelii Wierzb. ex Heuff. essential oil during different stages of development, with emphasis on chemotaxonomy. The most abundant compound class in the S. kitaibelii oil during examined phenological stages was oxygenated monoterpenes (21.3–61.2%), except vegetative stage, in which monoterpene hydrocarbons are dominant (51.1%). Geraniol, limonene, p-cymene and borneol are the most abundant compounds of essential oil during different stages of development. The highest variation in content, during plant development, was shown by the most dominant component, geraniol (coefficient of variation 112.3%). Chemometric analysis indicated two chemotypes: limonene/p-cymene/geraniol and limonene/p-cymene/borneol. We are of the opinion that the three most abundant EO components should determine the chemotype. Our results lead to the conclusion that essential oil isolated from the plant in 1 month should not be used to determine the chemotype.

ABSTRACT Various plants and natural compounds have been used traditionally to treat and prevent diseases, relieve pain, increase body strength, and heal skin injury. Achillea millefolium is a well-known plant of the Asteraceae family that has been extensively studied for its therapeutic properties in conditions, such as menstrual disorders, malaria, headache, cough, and skin injury. Several studies have shown that the topical application of different types of A. millefolium extracts (essential oil (EO), hydroalcoholic extract, etc.) improves the healing process of various skin injuries. Previous studies also highlighted the antibacterial, anti-inflammatory, antioxidant, and moisturizing effects of the A. millefolium extract on ameliorating skin injuries, caused by the presence of various potent constituents in the plant extract. This review aimed at overviewing the studies, focusing on A. millefolium’s possible effects on the different wound injuries.

ABSTRACT Humulus lupulus L. is a dioecious herbaceous perennial plant with a climbing habit, whose female inflorescences, commonly known as cones, produce and accumulate bitter substances and essential oils. The present study aimed to assess the adaptability of some American hop varieties (Cascade, Chinook, and Comet) in the Mediterranean environment of the Calabria region (Italy) through the evaluation of the morpho-biological and productive characteristics and the characterization of the aromatic traits of the inflorescences. Comet proved to be the most productive variety, while Chinook the earliest. Essential oils obtained by hydrdistillation were analysed by GC-FID and GC-MS. Myrcene, β-caryphyllene and α-humulene were the main components. The combination of morphological traits and the aromatic profiles could be adopted as tools to discriminate varieties. Comet was the most productive variety, while Chinook emerged as the earliest one. Concernng the essential oils Cascade and Comet showed similar profiles, Chinnok was different especially for the sesquiterpenes content.
