Methyl Salicylate(cas: 119-36-8) is a natural herbivore-induced plant volatile. It is a naturally occurring product in trees, legumes, exotic plants, vegetables, berries, and the primary constituent of the oil of wintergreen.Methyl Salicylate is produced from salicylic acid.Quality Control of Methyl Salicylate

ãA new slow-release formulation of methyl salicylate optimizes the alternative control of Sitobion avenae (Fabricius) (Hemiptera: Aphididae) in wheat fieldsã?was written by Wang, Kang; Liu, Jiahui; Zhan, Yidi; Liu, Yong. Quality Control of Methyl SalicylateThis research focused onwheat crop field pest control methyl salicylate release formulation; alginate bead; behavior manipulation; methyl salicylate; semiochemical control; slow-release formulation. The article conveys some information:

Some defects, such as the short persistence and lower release stability of Me salicylate (MeSA), must be resolved before efficient field application. To enhance the utilization efficacy of MeSA, a slow-release MeSA alginate bead was designed and tested to measure its release rate in a laboratory environment and to obtain insights into its ecol. effects in wheat fields. In laboratory tests, both the 2.5 and 10 mL formulations of MeSA alginate beads (hereafter referred to as MeSA 2.5 and MeSA 10) release stably and continuously for at least 15 days, whereas pure MeSA does so for only â?7 days. In field experiments, both the MeSA 2.5 bead and the MeSA 10 bead reduce the abundance of Sitobion avenae significantly and attract Metasyrphus corollae compared with the control. In addition, the effect of MeSA 10 beads is significantly greater than that of MeSA 2.5. The MeSA alginate bead we manufactured could be an efficient slow-release formulation. The MeSA 10 bead had a significantly greater effect on S. avenae population suppression, partly by attracting M. corollae in fields. In addition to this study using Methyl Salicylate, there are many other studies that have used Methyl Salicylate(cas: 119-36-8Quality Control of Methyl Salicylate) was used in this study.

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.Application of 119-36-8

And the article was published in Toxicological Sciences in 2019. Application of 119-36-8 The author mentioned the following in the article:

This in vitro study evaluated the “”triple protocol”” of dry decontamination, the ladder pipe system (a method for gross decontamination), and tech. decontamination for the decontamination of hair following chem. contamination. First, we assessed the efficacy of the 3 protocols, alone or in combination, on excised porcine skin and human hair contaminated with either Me salicylate (MS), phorate (PHR), sodium fluoroacetate (SFA), or potassium cyanide (KCN). A second experiment investigated the residual hair contamination following decontamination with the triple protocol at different intervals postexposure. In a third experiment, hair decontaminated after exposure to MS or PHR was evaluated for off-gassing. Though skin decontamination was highly effective, a substantial proportion (20%-40%) of the lipophilic compounds (MS and PHR) remained within the hair. The more water-soluble contaminants (SFA and KCN) tended to form much smaller reservoirs within the hair. Interestingly, substantial off-gassing of MS, a medium volatility chem., was detectable from triple-decontaminated hair up to 5 days postexposure. Overall, the decontamination strategies investigated were effective for the decontamination of skin, but less so for hair. These findings highlight the importance of contaminated hair serving as a source of potential secondary contamination by contact or inhalation. Therefore, consideration should be given to the removal of contaminated hair following exposure to toxic chems. In addition to this study using Methyl Salicylate, there are many other studies that have used Methyl Salicylate(cas: 119-36-8Application of 119-36-8) was used in this study.

Zou, Lai-Quan’s team published research in Physiology & Behavior in 2020 | CAS: 119-36-8

ãDecreasing prevalence of specific anosmia to non-steroid odorants from childhood to adolescenceã?was published in Physiology & Behavior in 2020. These research results belong to Zou, Lai-Quan; Vogt, Olivia; Schriever, Valentin A.; Croy, Ilona; Schaal, Benoist; Hummel, Thomas. Application In Synthesis of Methyl Salicylate The article mentions the following:

Specific anosmia is defined as the inability to detect a particular odorant, despite a normal olfactory function. Previous studies reported sex-related difference in detection threshold to steroid odorants, like androstenone or androstadienone during adolescence, and boys showed an increased detection threshold with age. However, such investigations have not been performed for non-steroid odorants. Hence, the current study investigated sex- and age-related effects on the prevalence of specific anosmia in children/adolescents aged 5-14 years (n = 800) to non-steroid odorants. The detection thresholds of three non-steroid odorants (bacdanol, methylsalicylate, and 3-hydrox-2-methyl-4-pyrone) with different mol. weights were measured. Results indicate that the rate of specific anosmia for all three odorants decreases from childhood to adolescence. This decrease is independent of sex and is most pronounced for odorants with higher mol. weight compared to the odorant with lower mol. weight Thus, the development of basic olfactory functions for these three odorants continues until adolescence. The effect of mol. weight suggests that the locus of effect is at the periphery of the olfactory system, due to changes in either olfactory receptor expression patterns or perireceptor events. In the part of experimental materials, we found many familiar compounds, such as Methyl Salicylate(cas: 119-36-8Application In Synthesis of Methyl Salicylate)

Wei, H.-s.’s team published research in Insect Molecular Biology in 2021 | CAS: 119-36-8

Wei, H.-s.; Qin, J.-h.; Cao, Y.-z.; Li, K.-b.; Yin, J. published their research in Insect Molecular Biology in 2021. The article was titled ãTwo classic OBPs modulate the responses of female Holotrichia oblita to three major ester host plant volatilesã?Quality Control of Methyl Salicylate The article contains the following contents:

Insects possess a fairly sophisticated olfactory system in their antennae to detect odorants essential for their survival and reproduction Among them, insect first perceives odor sources by odorant-binding proteins (OBPs) to locate host-plants. Me salicylate, (Z)-3-hexenyl acetate and di-Bu phthalate are major volatile components of Ulmus pumila and Ricinus communis and elicit strong responses of the scarab beetle Holotrichia oblita adults. However, olfactory perception of the scarab beetle to these odorant compounds is unclear. In the current study, we cloned the OBP6 and OBP7 of H. oblita. The expression pattern shows that the two genes were highly expressed in the antennae of female beetles. Binding assays verified that the HoblOBP6 had a better binding affinity to Me salicylate, and so did HoblOBP7 to (Z)-3-hexenyl acetate and di-Bu phthalate. The effect on the responses of female beetles to the three compounds was decreased significantly after these two genes were silenced by RNA interference. These results indicate that HoblOBP6 and HoblOBP7 are essential for female H. oblita perception of Me salicylate, (Z)-3-hexenyl acetate and di-Bu phthalate. Our study provides important insights into the olfactory mechanism of female H. oblita to ester plant volatiles and could facilitate the development of potential pest control strategies in the field. In the experiment, the researchers used many compounds, for example, Methyl Salicylate(cas: 119-36-8Quality Control of Methyl Salicylate)

Chien, Tiffany’s team published research in ACS Synthetic Biology in 2021 | CAS: 119-36-8

Chien, Tiffany; Jones, Drew R.; Danino, Tal published an article in 2021. The article was titled 《Engineered bacterial production of volatile me salicylate》, and you may find the article in ACS Synthetic Biology.Reference of Methyl Salicylate The information in the text is summarized as follows:

The engineering of microbial metabolic pathways over the last two decades has led to numerous examples of cell factories used for the production of small mols. These mols. have an array of utility in com. industries and as in situ expressed biomarkers or therapeutics in microbial applications. While most efforts have focused on the production of mols. in the liquid phase, there has been increasing interest in harnessing microbes’ inherent ability to generate volatile compounds Here, we optimized and characterized the production of Me salicylate, an aromatic compound found mainly in plants, using a common lab strain of E. coli. We utilized genetic components from both microbes and plants to construct the volatile metabolite circuit cassette. In order to maximize production, we explored expression of Me salicylate precursors, upregulation of expression by increasing ribosomal binding strength and codon optimization of the Me transferase gene obtained from plant Petunia x hybrida. Last, we validated and quantified the production of Me salicylate with liquid chromatog. or gas chromatog. mass spectrometry (LC-MS or GC-MS) and found that the codon optimized strain with precursor supplementation yielded the highest production compared to the other strains. This work characterizes an optimized metabolite producing genetic circuit and sets the stage for creation of an engineered bacteria diagnostic to be used in volatile assays. In the experiment, the researchers used many compounds, for example, Methyl Salicylate(cas: 119-36-8Reference of Methyl Salicylate)

《Multiscale orthogonal matching pursuit algorithm combined with peak model for interpreting ion mobility spectra and achieving quantitative analysis》 was written by Zhang, Genwei; Peng, Silong; Xie, Qiong; Yang, Liu; Cao, Shuya; Huang, Qibin. Quality Control of Methyl Salicylate And the article was included in Analytica Chimica Acta in 2020. The article conveys some information:

Ion mobility spectrometry is an important rapid anal. method. However, it is difficult to achieve quant. anal. when spectral peaks overlap. A new method for analyzing ion mobility spectra is presented here. The method achieves quant. anal. by combining the advantages of the peak model (in terms of optimal phys. and chem. interpretation of the system of interest) and the multiscale orthogonal matching pursuit algorithm (in terms of extracting characteristic peaks). A simulated data set, constructed using the peak model, containing overlapping peaks was analyzed to demonstrate the ability of the multiscale orthogonal matching pursuit algorithm to decompose overlapping peaks. Real data sets for Me salicylate and a mixture of acetone and Me salicylate at 16 concentrations were generated using a vapor generator (using permeation tubes). The characteristic peaks were extracted using the multiscale orthogonal matching pursuit algorithm. Univariate calibrations using the peak area and peak height were prepared to allow quant. analyses to be performed. Multivariate calibrations using partial-least-squares and poly-partial-least-squares were prepared and the results were compared with the univariate calibration results. Markedly better or similar predictions were made using the univariate calibration models involving phys. and chem. interpretations than using the multivariate calibration models.Methyl Salicylate(cas: 119-36-8Quality Control of Methyl Salicylate) was used in this study.

Barman, Monica’s team published research in Physiologia Plantarum in 2019 | CAS: 119-36-8

The author of 《Temporal relationship between emitted and endogenous floral scent volatiles in summer- and winter-blooming Jasminum species》 were Barman, Monica; Mitra, Adinpunya. And the article was published in Physiologia Plantarum in 2019. Recommanded Product: Methyl Salicylate The author mentioned the following in the article:

Jasminum spp. is cultivated for their fragrant flowers used in essential oil production and cosmetic uses. An attempt was made to study the temporal variations in floral scent volatiles composition including emitted, free endogenous and glycosyl-linked volatile compounds from two summer-blooming species namely, Jasminum auriculatum and Jasminum grandiflorum as well as from two winter-blooming species namely, Jasminum multiflorum and Jasminum malabaricum. The overall emitted volatile organic compounds (VOCs) were found to be highest when the matrix Porapak Q 80/100 was used with dichloromethane (DCM) as elution solvent. The floral volatile emission from bud to senescence exhibited nocturnal maxima pattern for both the summer-blooming species. Both the winter-blooming species emitted its highest concentration at noon. The free endogenous concentrations of all VOCs were low when corresponding emitted concentrations were high. Enzymic treatment of petal extract revealed that several aromatic volatiles including aromatic alcs. and monoterpenols are synthesized and stored in the flowers as water-soluble glycosides; these compounds were shown to accumulate in higher amounts in flowers at late bud stage. These findings indicate the utilization of the precursors, i.e. the volatile-conjugates, through hydrolysis followed by their release as free-volatiles at flower opening stage. The outcome as a whole suggests a linkage among the temporal pattern of emitted volatiles, free-endogenous volatiles and glycoside-bound volatile compounds in all above studied Jasminum spp. and provided an overview of their floral volatilome. In the experimental materials used by the author, we found Methyl Salicylate(cas: 119-36-8Recommanded Product: Methyl Salicylate)

Synthetic Route of C8H8O3In 2020 ,《Preharvest salicylate treatments enhance antioxidant compounds, color and crop yield in low pigmented-table grape cultivars and preserve quality traits during storage》 was published in Antioxidants. The article was written by Garcia-Pastor, Maria E.; Zapata, Pedro J.; Castillo, Salvador; Martinez-Romero, Domingo; Valero, Daniel; Serrano, Maria; Guillen, Fabian. The article contains the following contents:

Previous reports reported on the effectiveness of preharvest salicylic acid (SA) treatment on increasing fruit quality properties although no information is available about acetyl salicylic acid (ASA) and Me salicylate (MeSa) treatments. Thus, SA, ASA and MeSa were applied at 1, 5, and 10 mM in 2016 and at 1, 0.1 and 0.01 mM in 2017 to vines of ‘Magenta’ and ‘Crimson’ table grapes. Preharvest salicylate treatments at high concentration, 5 and 10 mM, delayed berry ripening and reduced crop yield, while ripening was accelerated and yield increased at lower concentrations In addition, SA, ASA, and MeSa treatments, at 1, 0.1, and 0.01 mM, improved berry color due to increased concentration of total and individual anthocyanins, for both cultivars. Quality parameters, and especially, antioxidant bioactive compounds, such as total phenolics and total and individual anthocyanins, were found at higher levels in treated berries at harvest and during prolonged cold storage, the highest effects being found in 0.1 mM MeSa treated table grapes. Overall, it could be concluded that MeSa treatment at 0.1 mM could be the most useful tool to increase bioactive compounds with antioxidant properties in table grape and in turn, their health beneficial properties, with addnl. effects on increasing crop yield, accelerating on-vine ripening process and maintaining quality traits during prolonged storage. In the experiment, the researchers used many compounds, for example, Methyl Salicylate(cas: 119-36-8Synthetic Route of C8H8O3)

Rivera, Monique J.’s team published research in Scientific Reports in 2020 | CAS: 119-36-8

《Evaluation of semiochemical based push-pull strategy for population suppression of ambrosia beetle vectors of laurel wilt disease in avocado》 was written by Rivera, Monique J.; Martini, Xavier; Conover, Derrick; Mafra-Neto, Agenor; Carrillo, Daniel; Stelinski, Lukasz L.. Name: Methyl Salicylate And the article was included in Scientific Reports in 2020. The article conveys some information:

Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae) bore into tree xylem to complete their life cycle, feeding on symbiotic fungi. Ambrosia beetles are a threat to avocado where they have been found to vector a symbiotic fungus, Raffaelea lauricola, the causal agent of the laurel wilt disease. We assessed the repellency of Me salicylate and verbenone to two putative laurel wilt vectors in avocado, Xyleborus volvulus (Fabricius) and Xyleborus bispinatus (Eichhoff), under laboratory conditions. Then, we tested the same two chems. released from SPLAT flowable matrix with and without low-dose ethanol dispensers for manipulation of ambrosia beetle populations occurring in com. avocado. The potential active space of repellents was assessed by quantifying beetle catch on traps placed ‘close’ (∼5-10 cm) and ‘far’ (∼1-1.5 m) away from repellent dispensers. Ambrosia beetles collected on traps associated with all in-field treatments were identified to species to assess beetle diversity and community variation. Xyleborus volvulus was not repelled by Me salicylate (MeSA) or verbenone in laboratory assays, while X. bispinatus was repelled by MeSA but not verbenone. Ambrosia beetle trap catches were reduced in the field more when plots were treated with verbenone dispensers (SPLAT) co-deployed with low-dose ethanol dispensers than when treated with verbenone alone. Beetle diversity was highest on traps deployed with low-dose ethanol lures. The repellent treatments and ethanol lures significantly altered the species composition of beetles captured in experiment plots. Our results indicate that verbenone co-deployed with ethanol lures holds potential for manipulating ambrosia beetle vectors via push-pull management in avocado. This tactic could discourage immigration and/or population establishment of ambrosia beetles in com. avocado and function as an addnl. tool for management programs of laurel wilt. The experimental process involved the reaction of Methyl Salicylate(cas: 119-36-8Name: Methyl Salicylate)

Wen, Ming’s team published research in Journal of Insect Physiology in 2019 | CAS: 119-36-8

In 2019,Journal of Insect Physiology included an article by Wen, Ming; Li, Ertao; Chen, Qi; Kang, Hui; Zhang, Shuai; Li, Kebin; Wang, Yinliang; Jiao, Yin; Ren, Bingzhong. Related Products of 119-36-8. The article was titled 《A herbivore-induced plant volatile of the host plant acts as a collective foraging signal to the larvae of the meadow moth, Loxostege sticticalis (Lepidoptera: Pyralidae)》. The information in the text is summarized as follows:

The meadow moth Loxostege sticticalis is a serious agricultural pest that feeds on the leaves of many economic crops, such as sugar beet, soybean, sunflower, and potato. In addition to the rapid migration of adult moths, the collective foraging behavior of the larvae is also thought to be involved in the search for new food sources and substantially contributes to the expansion of the infested area. However, whether and how the chem. signals take part in this process remains unknown. In this study, two larva-specific expressed odorants, LstiOR5 and LstiOR6, were successfully cloned and deophanized. A heterologous study on Xenopus laevis oocytes showed that several host plant volatiles could evoke LstiOR responses in a dose-dependent manner. One herbivore-induced plant volatile (HIPV) of soybean leaves, Me salicylate (MeSA), exerted attractive effects on the L. sticticalis larvae at all tested concentrations Further foraging choice assays showed that the L. sticticalis larvae preferred foraged soybean leaves over unforaged leaves. When MeSA was artificially added to unforaged leaves, the unforaged leaves were preferred over the foraged leaves. In addition, GC-MS anal. demonstrated that MeSA was induced by the foraging behavior of the larvae and acted as a collective food signal in L. sticticalis. Moreover, in situ hybridization showed that LstiOR5 was highly expressed in larval antenna neurons. When LstiOR5 was silenced, both the electrophysiol. response of the antenna to MeSA and the preference for foraged leaves were significantly decreased, suggesting that LstiOR5 is involved in the collective foraging behavior of L. sticticalis. Our results clarified the chem. signals that trigger the collective foraging behavior of L. sticticalis and provided more evidence for the mol. mechanism underlying the expansions of their infested areas at a peripheral olfactory sensing level. These findings could facilitate the development of potential control strategies for controlling this pest and provide a potential gene target that correlates with the collective foraging behavior of L. sticticalis, which might lead to better pest management. In the experiment, the researchers used many compounds, for example, Methyl Salicylate(cas: 119-36-8Related Products of 119-36-8)
