Volatile compounds and antibacterial effect of commercial mint cultivars – chemotypes and safety was written by Kowalczyk, Adam;Piatkowska, Elzbieta;Kus, Piotr;Marijanovic, Zvonimir;Jerkovic, Igor;Tuberoso, Carlo I. G.;Fecka, Izabela. And the article was included in Industrial Crops and Products in 2021.Name: Octyl acetate The following contents are mentioned in the article:

The taxonomy of Mentha species is complicated due to the possibility of hybridization, and the introduction of many cultivars of mint used mainly for industrial purposes is a big challenge for their correct identification. Multidirectional studies of new mint cultivars give the possibility to determine their chem. composition and safety in use. An anal. of the essential oils (EOs) obtained by hydrodistillation from the leaves of fifteen com. mints was performed using the GC-MS method. Addnl., the headspace volatile compound profiles of analyzed mint leaves were obtained by headspace solid-phase microextraction (HS-SPME/GC-MS). The essential oil yields were found to vary from 2.0-26.5 mL/kg. The GC-MS of EOs, as well as for the headspace compounds, showed large variation in their chem. composition The principal component anal. (PCA) enabled distinction of three groups of chemotypes among fifteen mint cultivars, characterized by the abundance of trans-piperitenone oxide, carvone or menthol and related compounds The use of these essential oils seems to be safe with respect to menthone, pulegone and menthofuran levels. The majority of isolated essential oils inhibited the growth of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, but the effectiveness of their antibacterial activity varies. The obtained results indicate a variability of chem. composition and antimicrobial properties within the analyzed mint cultivars. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Name: Octyl acetate).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Profiling of volatile organic compounds in wild indigenous medicinal ginger (Zingiber barbatum Wall.) from Myanmar was written by Shukurova, Musavvara Kh.;Asikin, Yonathan;Chen, Yanhang;Kusano, Miyako;Watanabe, Kazuo N.. And the article was included in Metabolites in 2020.Electric Literature of C10H20O2 The following contents are mentioned in the article:

The emissions of volatile organic compounds (VOCs) strongly depend on the plant species and are differently represented in specific taxa. VOCs have a degree of chem. diversity and also can serve as chemotaxonomic markers. Zingiber barbatum Wall. is a wild medicinal ginger plant endemic to Myanmar whose VOC composition has never been screened before. In this study, we screened the rhizome of Z. barbatum to identify the VOC composition by the application of gas chromatog. combined with time-of-flight-mass spectrometry (GC-TOF-MS). The resulting VOC profile of Z. barbatum showed that it consists mainly of monoterpenes (21%) and sesquiterpenes (30%). Intraspecific similarities and dissimilarities were found to exist between Z. barbatum genotypes in terms of VOC composition Four accessions (ZO191, ZO223, ZO217, and the control accession ZO105) collected from the Shan State and Mandalay region of Myanmar were found to share a similar VOC profile, while two accessions (ZO64 and ZO160) collected from the Bago region were found to vary in their VOC profiles compared with the control accession. The two identified compounds, i.e., α-bergamotene and β-(E)-guaiene may serve as discriminative chem. markers for the characterization of Z. barbatum species collected in these three geog. regions of Myanmar. This study represents a first attempt to identify and describe the VOCs in the medicinal species Z. barbatum that have not been reported to date. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Electric Literature of C10H20O2).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Electric Literature of C10H20O2

Virucidal Activity of Essential Oils From Citrus x aurantium L. Against Influenza A Virus H1N1:Limonene as a Potential Household Disinfectant Against Virus was written by Fadilah, Nurul Q.;Jittmittraphap, Akanitt;Leaungwutiwong, Pornsawan;Pripdeevech, Patcharee;Dhanushka, Darshana;Mahidol, Chulabhorn;Ruchirawat, Somsak;Kittakoop, Prasat. And the article was included in Natural Product Communications in 2022.Related Products of 112-14-1 The following contents are mentioned in the article:

This work explored the compositions of a crude extract of peels of Citrus x aurantium using a gas chromatog.-mass spectrometry (GC-MS) technique. The crude extract of peels of C. x aurantium was analyzed by GC-MS revealing the presence of limonene as the major compound, accounting for 93.7% of the total. Virucidal activity of the oil of C. x aurantium peels against influenza A virus H1N1 was evaluated by the ASTM E1053-20 method. Moreover, the virucidal activity was also investigated of D-limonene, the major terpene in essential oils of C. x aurantium, and its enantiomer L-limonene. The essential oil of the C. x aurantium peels produced a log reduction of 1.9 to 2.0, accounting for 99% reduction of the virus, while D- and L-limonene exhibited virucidal activity with a log reduction of 3.70 to 4.32 at concentrations of 125 and 250.0μg/mL, thus reducing the virus by 99.99%. Previous work found that D-limonene exhibited antiviral activity against herpes simplex virus, but L-limonene, an enantiomer of D-limonene, has never been reported for antiviral activity. This work demonstrates the antiviral activity of L-limonene for the first time. Moreover, this work suggests that concentrations of 0.0125% to 0.025% of either D- or L-limonene can possibly be used as a disinfectant against viruses, probably in the form of essential oil sprays, which may be useful disinfectants against the airborne transmission of viruses, such as influenza and COVID-19. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Related Products of 112-14-1).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Related Products of 112-14-1

Unraveling the potential of cryotolerant Saccharomyces eubayanus in Chardonnay white wine production was written by Parpinello, Giuseppina Paola;Ricci, Arianna;Folegatti, Barbara;Patrignani, Francesca;Lanciotti, Rosalba;Versari, Andrea. And the article was included in LWT–Food Science and Technology in 2020.Application In Synthesis of Octyl acetate The following contents are mentioned in the article:

This work investigated the suitability of the cryotolerant yeast Saccharomyces eubayanus to ferment Chardonnay must at different temperatures (10掳C, 12掳C, 16掳C, and 26掳C) over two vintages (2013 and 2014). The effect of added nitrogen was also evaluated. The strain’s fermentation parameters (maximum growth rate, lag phase, and asymptotic maximum) and cell growth were compared to the values for two reference Saccharomyces cerevisiae strains. Saccharomyces eubayanus showed its best fermentation performance at low temperatures (10掳C and 12掳C), with optimal kinetic parameters and high sugar consumption. Moreover, wines from the cryotolerant yeast showed a volatile acidity reduction of approx. 50%, and a 9% increase in total polyphenols, compared to the reference yeasts. At 16掳C the cryotolerant and control yeasts performed quite similarly, whereas at 26掳C the former displayed stuck fermentation For both yeasts, at 10掳C the nitrogen content did not affect maximum growth rate, whereas it did at 16掳C. Sensory analyses were run on the 2014 trials, showing differences in color, sweetness, and overall liking among wines obtained at 10掳C, whereas wines obtained at 16掳C differed only in color. Results demonstrate for the first time the Saccharomyces eubayanus suitability for low-temperature fermentation in white wine production, potentially enriching yeast biodiversity in winemaking. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Application In Synthesis of Octyl acetate).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application In Synthesis of Octyl acetate

Environmental Processing of Short-Chain Fatty Alcohols Induced by Photosensitized Chemistry of Brown Carbons was written by You, Bo;Li, Siyang;Tsona, Narcisse T.;Li, Jianlong;Xu, Li;Yang, Zhaomin;Cheng, Shumin;Chen, Qingcai;George, Christian;Ge, Maofa;Du, Lin. And the article was included in ACS Earth and Space Chemistry in 2020.Recommanded Product: Octyl acetate The following contents are mentioned in the article:

Fatty alcs. are known surfactants ubiquitous in the environment. They affect physicochem. and optical properties of aerosols and air/water interfaces; however, little is known about their photochem. Brown carbon (BrC) as photosensitizer, may initiate photochem. reactions of such non-photoactive surfactants. BrC was obtained by evaporating methylglyoxal/(NH₄)₂SO₄ or methylglyoxal/glycine (Gly) mixtures The BrC photo-sensitization ability was evidenced by its reaction with 1-octanol under UV irradiation measured by attenuated total reflection Fourier transform IR spectrometry, a surface-sensitive technique. Condensed phase products were determined by gas chromatog./mass spectrometry. A series of functionalized, unsaturated compounds were formed by a photo-sensitized reaction; more highly oxygenated compounds appeared after a long illumination time. This process contributed to formation of reactive volatile and semi-volatile organic compounds and could also trigger secondary chem. The reaction was probably initiated by electronically excited BrC upon exposure to UV radiation. A possible mechanism for fatty alcs. photo-sensitized degradation is proposed. It was also observed that BrC was easily photo-bleached; thus, it has a limited effect on radiative forcing. However, BrC can play an important role in aerosol and air/water interfaces.

Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: Octyl acetate

Sensory quality evaluation of Korla pear from different orchards and analysis of their primary and volatile metabolites was written by Liu, Yuan;Xiang, Simin;Zhang, Haipeng;Zhang, Hongyan;Wu, Cuiyun;Tang, Zhanghu;Wang, Jiangbo;Xu, Juan. And the article was included in Molecules in 2020.Synthetic Route of C10H20O2 The following contents are mentioned in the article:

Metabolites play vital roles in shaping the quality of fresh fruit. In this study, Korla pear fruit harvested from twelve orchards in South Xinjiang, China, were ranked in sensory quality by fuzzy logic sensory evaluation for two consecutive seasons. Then, gas chromatog.-mass spectrometry (GC-MS) was applied to determine the primary metabolites and volatile compounds Sensory evaluation results showed that the panelists were more concerned about ‘mouth feel’ and ‘aroma’ than about ‘fruit size’, ‘fruit shape’ and ‘peel color’. In total, 20 primary metabolites and 100 volatiles were detected in the pear fruit. Hexanal, (E)-2-hexenal, nonanal, d-limonene, (Z)-3-hexen-1-yl acetate and hexyl acetate were identified as the major volatile compounds Correlation anal. revealed that l-(+)-tartaric acid, hexanoic acid, trans-limonene oxide and 2,2,4-trimethyl-1,3-pentanediol diisobutyrate were neg. correlated with sensory scores. Furthermore, OPLS-DA results indicated that the fruit from three orchards with lower ranks in quality could be distinguished from other samples based on the contents of l-(+)-tartaric acid and other eight metabolites, which were all associated with ‘mouth feel’ and ‘aroma’. This study reveals the metabolites that might be closely associated with the sensory quality attributes of Korla pear, which may provide some clues for promoting the fruit quality in actual production This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Synthetic Route of C10H20O2).

Floral scent and pollinators of Cypripedium calceolus L. at different latitudes was written by Braunschmid, Herbert;Guilhot, Robin;Dotterl, Stefan. And the article was included in Diversity in 2021.Synthetic Route of C10H20O2 The following contents are mentioned in the article:

Floral scent is an important trait in plant-pollinator interactions. It not only varies among plant species but also among populations within species. Such variability might be caused by various non-selective factors, or, as has been shown in some instances, might be the result of divergent selective pressures exerted by variable pollinator climates. Cypripedium calceolus is a Eurasian deceptive orchid pollinated mainly by bees, which spans wide altitudinal and latitudinal gradients in mainly quite isolated populations. In the present study, we investigated whether pollinators and floral scents vary among different latitudes. Floral scents of three C. calceolus populations in the Southern Alps were collected by dynamic headspace and analyzed by gas chromatog. coupled to mass spectrometry (GC/MS). These data were completed by previously published scent data of the Northern Alps and Scandinavia. The scent characteristics were compared with information on pollinators recorded for present study or available in the literature. More than 80 scent compounds were overall recorded from plants of the three regions, mainly aliphatics, terpenoids, and aromatics Seven compounds were found in all samples, and most samples were dominated by linalool and octyl acetate. Although scents differed among regions and populations, the main compounds were similar among regions. Andrena and Lasioglossum species were the main pollinators in all three regions, with Andrena being relatively more abundant than Lasioglossum in Scandinavia. We discuss natural selection mediated by pollinators and neg. frequency-dependent selection as possible reasons for the identified variation of floral scent within and among populations and regions. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Synthetic Route of C10H20O2).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones.

Orange juice is one of the most consumed fruit juices worldwide and its adulteration has been a long-lasting concern. In this study, an untargeted volatile metabolomics using a comprehensive two-dimensional gas chromatog.-quadrupole mass spectrometry (GC x GC-qMS) was developed to systematically authenticate orange juice. At least 405 citrus whole fruits were collected, belongs to 58 types of orange samples and 23 types of non-orange citrus. The fruit juices were prepared in the laboratory and analyzed using the comprehensive GC x GC-qMS instrument. After optimizing the instrumental settings, this novel method was able to identified 鈭?50 volatiles in each juice sample, covering a variety types of hydrocarbons, esters, alcs., aldehydes, ketones and others. Combining with unsupervised principal component anal. and supervised partial least squares-discriminant anal. , this novel anal. tool was able to authenticate orange juice from a broad perspectives with a high accuracy in the cross-validation model: 1) differentiating orange juice from non-orange citrus juice (99% accuracy), 2) recognizing orange harvesting years (100% accuracy) and geog. origins (96% accuracy), and 3) distinguishing original pure orange juice from the reconstituted juice (94% accuracy). Key volatile metabolites associated with different categories of samples were also identified after thorough investigation of the loading values of the classification models. These metabolites have high potential to be used as food-markers to design targeted anal. methods for orange juice authentication. This novel comprehensive GC x GC-qMS-based method is ideal for governmental laboratories and the food industry to routinely authenticate orange juice. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Product Details of 112-14-1).

Composition variation of the essential oil from Ocimum basilicum L. cv. Genovese Gigante in response to Glomus intraradices and mild water stress at different stages of growth was written by Mota, Iris;Sanchez-Sanchez, Jose;Pedro, Luis G.;Sousa, Maria Joao. And the article was included in Biochemical Systematics and Ecology in 2020.Application of 112-14-1 The following contents are mentioned in the article:

In this study, a factorial experiment was carried out to investigate the effect of AMF (arbuscular mycorrhizal fungi) and water stress on the quality of fresh plants (through the anal. of essential oil composition) and also on the morphol. characteristics (in terms of biomass) of basil (Ocimum basilicum L. cv. Genovese Gigante). The factors included an arbuscular mycorrhizal fungus inoculation (Glomus intraradices), irrigation level (mild water stress, 60% Field capacity) and the interaction of both AMF and water stress. In addition, the effects of harvesting at two different developmental stages were assessed with respect to the plants tolerance to abiotic stress and the quality of the fresh plant. The main essential oil (EO) constituents for this cultivar were eugenol, which varied between 7.1 and 50.8%, and linalool, 17.0-54.7%, in all the samples. The highest relative amount of eugenol (50.8%) was obtained during the vegetative stage in plants under water stress whereas samples from the control presented 16.2% for this compound The samples which were significantly different from the control samples were the WS (water stress) samples from the vegetative stage. Addnl., this study suggests that AMF plants offset the adverse effect of water stress. In this context, and since the interaction of AMF and water stress did not significantly change the fresh plant quality, i.e. the essential oil profile in both stages of development, it is worthwhile considering this method of production Finally, this experiment permitted an understanding of the stressor thresholds of the species used and also that, compensatory responses occur at different time scales, including between generations and also during development (developmental plasticity). This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Application of 112-14-1).

Transcriptomic and Metabolomic Analyses Provide Insights into the Formation of the Peach-like Aroma of Fragaria nilgerrensis Schlecht. Fruits was written by Wang, Ai-Hua;Ma, Hong-Ye;Zhang, Bao-Hui;Mo, Chuan-Yuan;Li, En-Hong;Li, Fei. And the article was included in Genes in 2022.Reference of 112-14-1 The following contents are mentioned in the article:

Fragaria nilgerrensis Schlecht. is a wild diploid strawberry species. The intense peach-like aroma of its fruits makes F. nilgerrensis an excellent resource for strawberry breeding programs aimed at enhancing flavors. However, the formation of the peach-like aroma of strawberry fruits has not been comprehensively characterized. In this study, fruit metabolome and transcriptome datasets for F. nilgerrensis (HA; peach-like aroma) and its interspecific hybrids PA (peach-like aroma) and NA (no peach-like aroma; control) were compared. In total, 150 differentially accumulated metabolites were detected. The K-means anal. revealed that esters/lactones, including acetic acid, octyl ester, 未-octalactone, and 未-decalactone, were more abundant in HA and PA than in NA. These metabolites may be important for the formation of the peach-like aroma of F. nilgerrensis fruits. The significantly enriched gene ontol. terms assigned to the differentially expressed genes (DEGs) were fatty acid metabolic process and fatty acid biosynthetic process. Twenty-seven DEGs were predicted to be associated with ester and lactone biosynthesis, including AAT, LOX, AOS, FAD, AIM1, EH, FAH, ADH, and cytochrome P 450 subfamily genes. Thirty-five transcription factor genes were predicted to be associated with aroma formation, including bHLH, MYB, bZIP, NAC, AP2, GATA, and TCPfamily members. Moreover, we identified differentially expressed FAD, AOS, and cytochrome P 450 family genes and NAC, MYB, and AP2 transcription factor genes that were correlated with 未-octalactone and 未-decalactone. These findings provide key insights into the formation of the peach-like aroma of F. nilgerrensis fruits, with implications for the increased use of wild strawberry resources. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Reference of 112-14-1).

Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Reference of 112-14-1
