Abstract:
The subject of the study was the investigation of the chemical composition and antimicrobial activity of the essential oils (EOs) isolated from Calamintha sylvatica, C. vardarensis, C. nepeta and C. glandulosa, as well as their antibacterial activity in combination with antibiotics. The quantitative and qualitative analysis of EOs was performed using the GC/FID and GC/MS methods. The antimicrobial activity of EOs against six standard bacterial strains and one strain of yeast was tested using the broth microdilution method, while the antimicrobial activity of a combination of essential oils and gentamicin/ciprofloxacin was tested by the checkerboard method. The dominant components (> 10%) of the essential oils were: cis-piperitone epoxide and menthone ( C. sylvatica), pulegone and menthone ( C. vardarensis), pulegone and piperitenone ( C. nepeta), pulegone, piperitenone, menthone and piperitone ( C. glandulosa). EOs did not exhibit significant antimicrobial activity except the essential oil of C. vardarensis which was selectively active against Staphylococcus aureus (MIC - 21.25 μg/mL). The overall effect of essential oil-antibiotic combinations varied from synergistic (FICI ≤ 0.5) to antagonistic (FICI ≥ 2) depending on the bacterial strain tested.

Abstract:
Satureja macrostema is a plant that is located in various regions of Mexico and is used in a traditional way against illness. Essential oils (EOs) were obtained from leaves Satureja macrostema and the chemical composition was evaluated by gas chromatography–mass spectrometry (GC-MS). The antioxidant effect of the oil was assayed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and by Trolox Equivalent Antioxidant Capacity (TEAC). In vitro antibacterial activity against Escherichia coli and Staphylococcus aureus was determined using a broth microdilution assay and thin layer chromatography–direct bioautography (TLC-DB) to identify active antibacterial compounds. The EOs analysis showed 21 compounds, 99% terpenes, and 96% oxygenated monoterpenes, with trans-piperitone epoxide (46%), cis-piperitone epoxide (22%), and piperitenone oxide (11%) as more abundant compounds. Likewise, S. macrostema EOs showed an antioxidant activity of DPPH = 82%, with 50% free radical scavenging (IC50) = 7 mg/mL and TEAC = 0.005, an antibacterial effect against E. coli of 73% inhibition, and 81% over S. aureus at dose of 100 µL of undiluted crude oil. The TLC-DB assay showed that the most active compounds were derived from piperitone. The comparison with other studies on S. macrostema shows variability in the compounds and their abundances, which can be attributed to climatic factors and the maturity of plants with similar antioxidant and antibacterial activities.

Abstract:
The article presents data on the content and composition of the essential oil of Mentha longifolia (L.) L. plants growing in natural phytocenoses on the territory of Crimea and Abkhazia. It was found that dry raw materials in two samples from natural phytocenoses of Crimea contain 1.27 and 1.76% of essential oil per wet weight, three samples from phytocenoses of Abkhazia contain less essential oil - 0.68, 0.98 and 1.19 %. About 60 components have been identified. Two new chemotypes were identified for Crimea: carvone-piperitone (mass fraction of carvone is 66.65%, piperitone oxide - 14.37%) and piperitone-sabinene (mass fraction of piperitone oxide - 55.19% and cis-sabinene hydrate - 23.51%), and two for Abkhazia: terpene-caryophyllene (α-terpinyl acetate - 51.48%; β-caryophyllene - 9.26%), piperitone-non-petalactone (piperitone oxide - 46.29%; nepetalactone 4aa, 7a, 7aa - 34.85%). These Mentha longifolia chemotypes are promising for use in the food, chemical, pharmaceutical and perfume industries.

Abstract:
Thermal stabilities of four major components (l-menthol, l-menthone, piperitone, and l-menthyl acetate) of Japanese mint essential oil were evaluated via subcritical water treatment. To improve experimental throughput for measuring compound stabilities, a small-scale subcritical water treatment method using ampoule bottles was developed and employed. A mixture of the four major components was treated in subcritical water at 180–240 °C for 5–60 min, and then analyzed by gas chromatography. The results indicated that the order of thermal resistance, from strongest to weakest, was: l-menthyl acetate, l-menthol, piperitone, and l-menthone. In individual treatments of mint flavor components, subsequent conversions of l-menthyl acetate to l-menthol, l-menthol to l-menthone, l-menthone to piperitone, and piperitone to thymol were observed in individual treatments at 240 °C for 60 min. As the mass balance between piperitone and thymol was low, the hydrothermal decomposition of the components was considered to have occurred intensely during, or after the conversion. These results explained the degradation of mint essential oil components under subcritical water conditions and provided the basis for optimizing the extraction conditions of mint essential oils using subcritical water.

Abstract:
Water-distilled essential oil from Clinopodium chinense (Labiatae) aerial parts at the flowering stage was analyzed by gas chromatography–mass spectrometry. Thirty-five compounds, accounting for 99.18% of the total oil, were identified, and the main components of the essential oil of C. chinense were spathulenol (18.54%), piperitone (18.9%), caryophyllene (12.04%), and bornyl acetate (8.14%). Based on bioactivity-directed fractionation, bornyl acetate, caryophyllene, and piperitone were identified from the essential oil. The essential oil possessed fumigant toxicity against booklice (Liposcelis bostrychophila) with a 50% lethal concentration (LC50) value of 423.39 μg/liter, while the isolated constituents, bornyl acetate and piperitone, had LC50 values of 351.69 and 311.12 μg/liter against booklice, respectively. The essential oil also exhibited contact toxicity against L. bostrychophila with an LC50 value of 215.25 μg/cm2. Bornyl acetate, caryophyllene, and piperitone exhibited acute toxicity against booklice with LC50 values of 321.42, 275.00, and 139.74 μg/cm2, respectively. The results indicated that the essential oil and its isolated constituents have potential for development into natural insecticides or fumigants for control of insects in stored grains.

Abstract:
Un grand vin de garde se distingue par sa capacité à se bonifier avec le temps, exprimant alors une complexité aromatique particulièrement attendue par les dégustateurs. L’apparition du bouquet de vieillissement, signature de la qualité organoleptique des grands vins vieillis en bouteille, est un des phénomènes les plus impressionnants de l’œnologie mais également l’un des plus mal connus. En effet, ses déterminants sensoriels et moléculaires ont jusqu’à présent été peu étudiés. Grâce à une approche holistique séquencée en trois étapes, nous avons pu décrypter sensoriellement le concept du bouquet de vieillissement des vins rouges de Bordeaux. Une définition sensorielle partagée par des professionnels du vin a pu émerger, s’articulant autour de huit notes aromatiques principales : « sous-bois », « truffe », « fruits frais rouges et noirs », « épicé », « réglisse », « menthe », « grillé » et « empyreumatique ». D’autre part, nous avons pu souligner l’importance de l’expertise dans la définition d’un tel concept olfactif, nécessitant à la fois des connaissances œnologiques, des compétences sensorielles et des ressources lexicales. Par une étude moléculaire ciblée sur certaines classes de molécules aromatiques se formant et/ou conservées au cours du vieillissement en bouteille, nous avons pu identifier que plusieurs composés soufrés volatils tels le sulfure de diméthyle, le 2-furaneméthanethiol et le 3-sulfanylhexanol contribuaient activement à la typicité du bouquet de vieillissement. Présents à des teneurs significativement plus élevées dans les vins rouges exprimant un bouquet de vieillissement, nous avons montré que ces composés volatils participaient plus particulièrement aux notes aromatiques caractéristiques de sous-bois, truffe et empyreumatique. La mise en œuvre de fractionnements d’extraits de vins et de reconstitutions aromatiques, puis l’application de la GC-O et de la GC-MS sur les fractions d’intérêt ont permis par la suite d’identifier la D,L-pipéritone, un monoterpène associé pour la première fois aux nuances de menthe typiques du bouquet de vieillissement des vins rouges de Bordeaux. Enfin, nous avons montré que certains paramètres du terroir pouvaient influencer l’expression aromatique du bouquet de vieillissement. La mesure du rapport isotopique (δC13) de l’éthanol a permis de retracer l’état hydrique des vignes ayant produit les vins étudiés et a montré qu’une contrainte hydrique modérée ou forte de la vigne était favorable à cette typicité. De plus, la différence sensorielle de la note menthe observée entre les vins rouges de Bordeaux semble trouver son origine dans la nature du cépage, avec des teneurs en D,L-pipéritone significativement plus importantes dans les vins pour lesquels le Cabernet Sauvignon est le cépage prédominant<br>A wine with ageing potential is noticeable by its ability to improve over time, expressing the aromatic complexity particularly expected by wine tasters. The development of wine ageing bouquet, the "signature" of the organoleptic quality of fine wines aged in bottle, is one of the most fascinating but least known phenomena in oenology. Indeed, both its sensory and molecular markers are poorly documented.A three-step holistic approach made it possible to decipher the sensory characteristics of the ageing bouquet of red Bordeaux wines. More precisely, a shared sensory definition emerged among wine professionals, structured around eight main aromatic notes: "undergrowth", "truffle", "fresh red- and black berry fruits", "spicy», "liquorice", "mint», "toasted" and "empyreumatic". Furthermore, the importance of expertise based on oenological knowledge, sensory skills, and lexical capabilities in defining olfactory concepts was highlighted. A molecular study, targeting specific classes of aromatic compounds formed and/or preserved during bottle ageing, identified dimethyl sulphide, 2-furanmethanethiol and 3-sulfanylhexanol as key contributors to the typicality of wine ageing bouquet. These volatile compounds were present in the highest concentrations in all wines with an ageing bouquet and participated more specifically in their undergrowth, truffle, and empyreumatic aromas. Subsequently, wine fractionations and aromatic reconstitutions, analyzed by both GC-O and GC-MS, were used to identify D,L-piperitone, a monoterpene which was shown for the first time to be involved in the typical mint nuances in the ageing bouquet of red Bordeaux wines. Finally, influence of some parameters of “terroir” was highlighted. Isotope ratio measurement (δC13) in ethanol of studied wines was used as an indicator of vine water status and revealed that a moderate to severe water deficit was in favor to the genesis of a wine ageing bouquet. Interestingly, the sensory difference in minty character observed in red Bordeaux wines apparently originated from grapes, as D,L-piperitone levels were significantly higher in wines where Cabernet Sauvignon was dominant

A number of Lippia species can be found in the Caatinga biome in Northeastern Brazil, such as Lippia bromelyana Moldenke, endemic to the state of Bahia. This study investigated the chemical composition, acute toxicity, antinociceptive and anti-inflammatory effect of the leaf essential oil of L. bromelyana (EOLB) in mice.The chemical composition of EOLB, assessed by gas chromatography with flame ionization detection (GC/FID) and gas chromatography-mass spectrometry (GC/MS), detected limonene (29.90%) and piperitenone oxide (26.91%) as major compounds. Intraperitoneal administration of 300 mg/kg of EOLB caused no acute toxic effects or deaths in the mice. At doses of 75, 150 and 300 mg/kg caused no changes in their motor activity in the rotarod test, but promoted a significant antinociceptive effect on abdominal contortions in the acetic acid-induced constriction test, in both phases of the formalin test, glutamate or cinnamaldehyde-induced nociception tests and the Randall-Selitto test. In the hot plate test, EOLB (150 or 300 mg/kg) increased latency at 30, 60 and 120 min after administration; at a dose of 300 mg/kg, the action reversed by naloxone suggests participation of the opioid pathway. Moreover, EOLB (75, 150 or 300 mg/kg) significantly reduced the inflammatory effect of carrageenan in the paw edema test.
