《Evaluation of the perceptual interaction among ester aroma compounds in cherry wines by GC-MS, GC-O, odor threshold and sensory analysis: An insight at the molecular level》 was written by Niu, Yunwei; Wang, Pinpin; Xiao, Zuobing; Zhu, Jiancai; Sun, Xiaoxin; Wang, Ruolin. Category: esters-buliding-blocksThis research focused onwine ester aroma compound; Aroma intensity; Ester compounds; Olfactory threshold; Perceptual interaction. The article conveys some information:

The ester aroma profiles of five Chinese cherry wines and the perceptual interaction among esters were investigated in this study. 24 esters were identified by Gas chromatog.-olfactometry (GC-O) and Gas Chromatog.-Mass Spectrometer (GC-MS). According to addition/omission anal., seven volatile compounds among them were selected and studied using sensory profiling and multivariate statistic methods such as Principal Component Anal. (PCA). In sensory anal., a significant reduction of olfactory threshold for total aromatic reconstitution was induced by the addition among each of them in Feller’s additive model, which demonstrated their synergistic effects. The σ/τ plot showed that most of them were followed by a partial addition behavior. Furthermore, PCA indicated that the addition among each of them had a significant effect on fruity, floral, sweet and fermentation aroma intensity. Specifically, Et decanoate and Me salicylate at sub-threshold concentrations were also likely to contribute to overall aroma. The results of perceptual interaction were mainly influenced by chem. structure and mol. polarity. The experimental process involved the reaction of Methyl Salicylate(cas: 119-36-8Category: esters-buliding-blocks)

Methyl Salicylate(cas: 119-36-8) has been used: as a component of clarifying solution for treating Mongolian gerbil cochlea intact for immunofluorescence analysis, as a plant elicitor to test its effect on reducing the whitefly population from tomato plants.SDS of cas: 119-36-8

In 2019,Food Chemistry included an article by Chen, Qincao; Zhu, Yin; Dai, Weidong; Lv, Haipeng; Mu, Bing; Li, Pengliang; Tan, Junfeng; Ni, Dejiang; Lin, Zhi. SDS of cas: 119-36-8. The article was titled 《Aroma formation and dynamic changes during white tea processing》. The information in the text is summarized as follows:

The formation of and dynamic changes in aroma during white tea processing have not previously been systematically investigated. In this study, advanced comprehensive two-dimensional gas chromatog.-time-of-flight mass spectrometry was employed to investigate the mechanism of white tea aroma formation. A total of 172 volatiles were identified and mainly comprising endogenous volatiles, which displayed diverse change trends during the withering period. In this process, free aroma precursor amino acids and glycosidically bound volatiles (GBVs) were found to contribute to the formation of white tea aroma, with the differential expression of aroma-related key genes accounting for various accumulation of endogenous volatiles and GBVs. In addition, the drying was also shown to play an important role in the formation of white tea aroma. Our study provides the first characterization of white tea aroma formation and establishes a theor. basis for quality control during white tea processing operations. In addition to this study using Methyl Salicylate, there are many other studies that have used Methyl Salicylate(cas: 119-36-8SDS of cas: 119-36-8) was used in this study.

The article was titled 《Safety assessment of the process Drava International, based on Starlinger deCON technology, used to recycle post-consumer PET into food contact materials》, and you may find the article in EFSA Journal.Quality Control of Methyl Salicylate The information in the text is summarized as follows:

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Drava International (EU register number RECYC217), which uses the Starlinger deCON technol. The input material is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, e.g. bottles, including no more than 5% PET from non-food consumer applications. The flakes are preheated before being submitted to solid-state polycondensation (SSP) in a reactor at high temperature under vacuum and Having examined the challenge test provided, the Panel concluded that the preheating (step 2) and the decontamination in the SSP reactor (step 3) are critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, pressure, residence time and It was demonstrated that this recycling process is able to ensure a level of migration of potential unknown contaminants into food below the conservatively modelled migration of 0.1μg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process is not considered to be of safety concern, when used at up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill. The final articles made of this recycled PET are not intended to be used in microwave or conventional ovens and such uses are not covered by this evaluation. The experimental process involved the reaction of Methyl Salicylate(cas: 119-36-8Quality Control of Methyl Salicylate)

Luo, Binsheng’s team published research in Food Chemistry in 2021 | CAS: 119-36-8

Luo, Binsheng; Kastrat, Ertan; Morcol, Taylan; Cheng, Haiping; Kennelly, Edward; Long, Chunlin published an article in 2021. The article was titled 《Gaultheria longibracteolata, an alternative source of wintergreen oil》, and you may find the article in Food Chemistry.Electric Literature of C8H8O3 The information in the text is summarized as follows:

Gaultheria longibracteolata (Ericaceae) has been traditionally used by different linguistic groups in Yunnan Province, China, but it has not been well studied. Through our ethnobotanical study in Luchun County of Yunnan, we found that this species has multiple traditional uses including food, medicine, and worship. The essential oils from the root, stem, and leaf were investigated by both GC-MS and anti-bacterial assays. The GC-MS study showed that Me salicylate is the main (>90%) component of the essential oil, and the oil composition extracted from different plant parts showed some similarities. The oil of G. longibracteolata displayed antimicrobial activity against Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus, which is likely due to its Me salicylate content. Gautheria longbracteolata appears to be a useful natural wintergreen oil substitute, but further studies are needed to develop this product. In the experiment, the researchers used Methyl Salicylate(cas: 119-36-8Electric Literature of C8H8O3)

Yang, Jun-Nan’s team published research in Insect Science in 2021 | CAS: 119-36-8

Yang, Jun-Nan; Wei, Jia-Ning; Kang, Le published an article in 2021. The article was titled 《Feeding of pea leafminer larvae simultaneously activates jasmonic and salicylic acid pathways in plants to release a terpenoid for indirect defense》, and you may find the article in Insect Science.Recommanded Product: Methyl Salicylate The information in the text is summarized as follows:

The pea leafminer, Liriomyza huidobrensis, is an important pest species affecting ornamental crops worldwide. Plant damage consists of oviposition and feeding punctures created by female adult flies as well as larva-bored mines in leaf mesophyll tissues. How plants indirectly defend themselves from these two types of leafminer damage has not been sufficiently investigated. In this study, we compared the indirect defense responses of bean plants infested by either female adults or larvae. Puncturing of leaves by adults released green leaf volatiles and terpenoids, while larval feeding caused plants to addnl. emit Me salicylate and (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene (TMTT). Puncturing of plants by female adults induced increases in jasmonic acid (JA) and JA-related gene expressions but reduced the expressions of salicylic acid (SA)-related genes. In contrast, JA and SA and their-related gene expression levels were increased significantly by larval feeding. The exogenous application of JA+SA significantly triggered TMTT emission, thereby significantly inducing the orientation behavior of parasitoids. Our study has confirmed that larval feeding can trigger TMTT emission through the activation of both JA and SA pathways to attract parasitoids; however, TMTT alone is less attractive than the complete blend of volatiles released by infested plants. In the experiment, the researchers used Methyl Salicylate(cas: 119-36-8Recommanded Product: Methyl Salicylate)

Shimizu, Kohei’s team published research in Plant Journal in 2022 | CAS: 119-36-8

In 2022,Shimizu, Kohei; Suzuki, Hitomi; Uemura, Takuya; Nozawa, Akira; Desaki, Yoshitake; Hoshino, Ryosuke; Yoshida, Ayako; Abe, Hiroshi; Nishiyama, Makoto; Nishiyama, Chiharu; Sawasaki, Tatsuya; Arimura, Gen-ichiro published an article in Plant Journal. The title of the article was 《Immune gene activation by NPR and TGA transcriptional regulators in the model monocot Brachypodium distachyon》.SDS of cas: 119-36-8 The author mentioned the following in the article:

The nonexpressor of pathogenesis-related (NPR) gene family is well known to play a crucial role in transactivation of TGA transcription factors for salicylic acid (SA)-responsive genes, including pathogenesis-related protein 1 (PR1), during plants immune response after pathogen attack in the model dicot Arabidopsis thaliana. However, little is known about NPR gene functions in monocots. We therefore explored the functions of NPRs in SA signaling in the model monocot Brachypodium distachyon. BdNPR1 and BdNPR2/3 share structural similarities with A. thaliana AtNPR1/2 and AtNPR3/4 subfamilies, resp. The transcript level of BdNPR2 but not BdNPR1/3 appeared to be pos. regulated in leaves in response to Me salicylate. Reporter assays in protoplasts showed that BdNPR2 pos. regulated BdTGA1-mediated activation of PR1. This transactivation occurred in an SA-dependent manner through SA binding at Arg468 of BdNPR2. In contrast, BdNPR1 functioned as a suppressor of BdNPR2/BdTGA1-mediated transcription of PR1. Collectively, our findings reveal that the TGA-promoted transcription of SA-inducible PR1 is orchestrated by the activator BdNPR2 and the repressor BdNPR1, which function competitively in B. distachyon. In the experiment, the researchers used Methyl Salicylate(cas: 119-36-8SDS of cas: 119-36-8)

Prateeksha’s team published research in Scientific Reports in 2019 | CAS: 119-36-8

In 2019,Scientific Reports included an article by Prateeksha; Barik, Saroj Kanta; Singh, Brahma Nand. Related Products of 119-36-8. The article was titled 《Nanoemulsion-loaded hydrogel coatings for inhibition of bacterial virulence and biofilm formation on solid surfaces》. The information in the text is summarized as follows:

The indiscriminate use of antibiotics has led to the emergence of drug-resistant bacteria which has become one of the biggest challenges of the twenty-first century for the researchers to combat and in turn search for novel targets which could lead to the development of effective and sustainable therapies. Inhibition of biofilm formation and virulence of bacterial pathogens is an emerging approach to address the challenges related to bacterial infections. To suppress the virulence and biofilm formation by Escherichia coli O157:H7 (ECOH), we developed stable nanoemulsion (NE) of Gaultheria fragrantissima Wall. essential oil′s (EO) bioactive compounds, viz., eugenol (E-NE) and Me salicylate (MS-NE) that showed significantly higher anti-biofilm and anti-virulence activities as compared to eugenol and Me salicylate without affecting ECOH planktonic cell growth. Transcriptional anal. showed that E-NE and MS-NE reduced the expression of genes, including curli, type I fimbriae, Shiga-like toxins, quorum sensing, and ler-controlled toxins, which are needed for biofilm formation, pathogenicity, and attachment. E-NE and MS-NE loaded hydrogel coatings showed superior anti-biofilm activity against ECOH on glass, plastic and meat surfaces as compared to eugenol and Me salicylate loaded coatings. Conclusively, NE-loaded hydrogel coatings could be used in combating ECOH infection on solid surfaces through anti-biofilm and anti-virulence strategies. In the part of experimental materials, we found many familiar compounds, such as Methyl Salicylate(cas: 119-36-8Related Products of 119-36-8)

Southworth, Felicity’s team published research in PLoS One in 2020 | CAS: 119-36-8

The author of 《A controlled cross-over study to evaluate the efficacy of improvised dry and wet emergency decontamination protocols for chemical incidents》 were Southworth, Felicity; James, Thomas; Davidson, Louise; Williams, Natalie; Finnie, Thomas; Marczylo, Tim; Collins, Samuel; Amlot, Richard. And the article was published in PLoS One in 2020. Application In Synthesis of Methyl Salicylate The author mentioned the following in the article:

The UK Initial Operational Response (IOR) to chem. incidents includes improvised decontamination procedures, which use readily available materials to rapidly reduce risk to potentially exposed persons. A controlled, cross-over human volunteer study was conducted to investigate the effectiveness of improvised dry and wet decontamination procedures on skin, both alone, and in sequence. A simulant contaminant, Me salicylate (MeS) in vegetable oil with a fluorophore was applied to three locations (shoulder, leg, arm). Participants then received no decontamination (control) or attempted to remove the simulant using one of three improvised protocols (dry decontamination; wet decontamination; combined dry and wet decontamination). Simulant remaining on the skin following decontamination was quantified using both Gas Chromatog. Tandem Mass Spectrometry (GC-MSMS) for anal. of MeS and UV imaging to detect fluorophores. Addnl., urine samples were collected for 24 h following application for anal. of MeS. Significantly less simulant was recovered from skin following each improvised decontamination protocol, compared to the no decontamination control. Further, combined dry and wet decontamination resulted in lower recovery of simulant when compared to either dry or wet decontamination alone. Irresp. of decontamination protocol, significantly more simulant remained on the shoulders compared to either the arms or legs, suggesting that improvised decontamination procedures are less effective for difficult to reach areas of the body. There was no effect of decontamination on excreted MeS in urine over 24 h. Overall, findings indicate that improvised decontamination is an effective means of rapidly removing contaminants from skin, and combinations of improvised approaches can increase effectiveness in the early stages of decontamination and in the absence of specialist resources at an incident scene. However, the variable control and consistency of improvised decontamination techniques means that further intervention is likely to be needed, particularly for less accessible areas of the body. In addition to this study using Methyl Salicylate, there are many other studies that have used Methyl Salicylate(cas: 119-36-8Application In Synthesis of Methyl Salicylate) was used in this study.
