Application In Synthesis of 3-Hydroxydihydrofuran-2(3H)-one And the article was included in Food Chemistry on April 25 ,2019. The article conveys some information:

This study aimed to evaluate the effect of the process time (5, 10, and 15 min) and flow rate (10, 20, and 30 mL/min) of cold plasma technol. on physio-chem. characteristics (pH), bioactive compounds (DPPD, Total Phenolic Compounds, ACE-inhibitory activity values), fatty acid composition, and volatile compounds profile of chocolate milk drink. The mild (lower flow rate and process time) and more severe (higher flow rate and process time) conditions led to a reduction of the bioactive compounds (total phenolic compounds and ACE-inhibitory activity), changes in fatty acid composition (increased saturated fatty acid and decreased monounsaturated fatty acid and polyunsaturated fatty acid), less favorable health indexes (higher atherogenic, thrombogenic and hypercholesterolemic saturated fatty acids and lower desired fatty acids), and lower number of volatile compounds In contrast, in intermediate cold plasma conditions, an adequate concentration of bioactive compounds, fatty acid composition, and health indexes, and increased number of volatile compounds (ketones, esters, and lactones) were observed Overall, cold plasma technol. has proven to be an interesting alternative to chocolate milk drinks, being of paramount importance the study of the cold plasma process parameters.

And the article was published in Pharmaceuticals in 2020. Category: tetrahydrofurans The author mentioned the following in the article:

In the current study, we present the correlation between the capability of laser-induced breakdown spectroscopy (LIBS) to monitor the elemental compositions of plants and their biol. effects. The selected plant, Moringa oleifera, is known to harbor various minerals and vitamins useful for human health and is a potential source for pharmaceutical interventions. From this standpoint, we assessed the antibacterial and in vitro cytotoxicity of the bioactive components present in Moringa oleifera seed (MOS) extract Detailed elemental anal. of pellets of MOSs were performed via LIBS. Furthermore, the LIBS outcome was validated using gas chromatog.-mass spectrometry (GC-MS). The LIBS signal was recorded, and the presence of the essential elements (Na, Ca, Se, K, Mg, Zn, P, S, Fe and Mn) in the MOSs were examined The bactericidal efficacy of the alc. MOS extract was examined against Escherichia coli (E. coli) and Staphylococcus aureus(S. aureus) by agar well diffusion (AWD) assays and SEM (SEM), which depicted greater inhibition against Gram-pos. bacteria. The validity and DNA nuclear morphol. of human colorectal carcinoma cells (HCT-116) cells were evaluated via an MTT assay and DAPI staining. The MTT assay results manifested a profoundly inhibitory action of MOS extract on HCT116 cell growth. Addnl., MOS extracts produced inhibitory action in colon cancer cells (HCT-116), whereas no inhibitory action was seen using the same concentrations of MOS extract on HEK-293 cells (non-cancerous cells), suggesting that MOS extracts could be non-cytotoxic to normal cells. The antibacterial and anticancer potency of these MOS extracts could be due to the presence of various bioactive chem. complexes, such as Et ester and D-allose and hexadecenoic, oleic and palmitic acids, making them an ideal candidate for pharmaceutical research and applications. The results came from multiple reactions, including the reaction of 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Category: tetrahydrofurans)

In 2019,ChemCatChem included an article by Jensen, Pernille Rose; Taarning, Esben; Meier, Sebastian. Quality Control of 3-Hydroxydihydrofuran-2(3H)-one. The article was titled 《Probing the Lewis Acid Catalyzed Acyclic Pathway of Carbohydrate Conversion in Methanol by In Situ NMR》. The information in the text is summarized as follows:

Future bioindustries will rely on the formation of diverse chems. at high yield through various reaction pathways. These pathways include reactions to a series of alpha-hydroxy esters and acids that can be formed from the conversion of C3-C6 carbohydrates by Lewis acidic catalysts in alcs. and water. Definitive kinetic and mechanistic insights to support the development of carbohydrate conversion processes are arguably less developed than for analogous biocatalytic processes. Here, we visualize acyclic pathways of carbohydrate dehydration, using the acyclic C4 carbohydrate erythrulose as a probe mol. for the conversion by homogeneous SnCl4 in methanol. In situ studies allow the detection of previously postulated intermediates, identify the branch point to competing products and provide energetic and mechanistic insight by kinetic anal. Reversibility of reactions, stereoselectivity and differential propensity for deuterium incorporation in competing pathways can be tracked by the formation of compounds with asym. mass distribution.

Recommanded Product: 19444-84-9 And the article was included in Fuel Processing Technology on April 30 ,2019. The article conveys some information:

Comprehension in hemicellulose pyrolysis is critical to generate renewable fuel and valuable chem. Herein, a self-designed tubular reactor was applied to observe the appearance alteration and chem. structure evolution during the whole xylan pyrolysis process. Before 200°C, it was free moisture removal stage without significant chem. structure alteration. Xylan began to depolymerize at 200°C corresponding with the appearance change from its original state to dark brown, cleavage of branched-chain and primary product acids & ketones generation. The main chain of xylan was completely broken at 250-350°C via β-1,4-glycosidic bond cleavage, dehydration, decarboxylation, and decarbonylation reaction. Acids were mainly originated from hemicellulose pyrolysis. The typical signals from FTIR, 13C CP/MAS NMR were disappeared at 350°C. In the carbonation stage, the C/H and C/O ratio reached 2.01 and 4.54, leading to the aromaticity enhancement of char and formation of carbon-centered radicals.3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Recommanded Product: 19444-84-9) was used in this study.

The Chrysopogon zizanioides plant possesses multiple traditional uses, especially in therapeutics, but only a few articles have reported its biol. activity. Hence, the present study was planned to explore the phytochem. constituents, cytotoxic potential, radical scavenging activity, and GC/MS (Gas chromatog. & Mass spectrometry) anal. of the vetiver root extracts The roots extracted with different solvents exhibited more significant phytochem. constituents in polar solvents in comparison to non-polar ones, favoring the extraction of a greater number of components in highly polar solvents. All the extracts were tested for their cytotoxicity using SRB (Sulforhodamine B) assay. They confirmed ethanolic extract as a potent extract with GI50 56±0.5 μg/mL in oral cancer (SCC-29B) along with no cytotoxicity in healthy cells (Vero cells), making it a safer therapeutic option in comparison to standard Adriamycin. This extract was also analyzed for its antioxidant potential by DPPH (1,1-Diphenyl-2-picrylhydrazyl) assay with IC50 value 10.73 μg/mL, which was quite comparable to Ascorbic acid having IC50 value 4.61 μg/mL. The quant. anal. of ethanolic extract exhibited 107 compounds amongst which Khusenic acid, Ascorbic acid, Junipen, gamma-Himachalene, alpha-Guaiene were the majorly occurring compounds that can be explored further for their cytotoxic activity.

In 2022,Energies (Basel, Switzerland) included an article by Wu, Haijun; Shakeel, Usama; Zhang, Quan; Zhang, Kai; Xu, Xia; Xu, Jian. COA of Formula: C4H6O3. The article was titled 《Ethanol-Assisted Hydrothermal Liquefaction of Poplar Using Fe-Co/Al2O3 as Catalyst》. The information in the text is summarized as follows:

Although the conversion of lignocellulosic biomass into bio-oil with high yield/quality through hydrothermal liquefaction (HTL) is promising, it still faces many challenges. In this study, a Fex-Co(1-x)/Al2O3 catalyst was prepared with the coprecipitation method and low-content ethanol was used as the cosolvent for the HTL of poplar. The results showed that the Fex-Co(1-x)/Al2O3 catalyst significantly promoted the yield and energy recovery rate (ERR) of bio-oil compared with the control (10% ethanol content). At 260 °C for 30 min, 60Fe-40Co/Al2O3 had the best catalytic effect, achieving the highest bio-oil yield (67.35%) and ERR (93.07%). As a multifunctional bimetallic catalyst, Fex-Co(1-x)/Al2O3 could not only increase the degree of hydrogenation deoxidization of the product but also promote the diversity of phenolic compounds gained from lignin. The bio-oil obtained from HTL with Fex-Co(1-x)/Al2O3 as catalyst contained lower heterocyclic nitrogen, promoting the transfer of more bio-oil components to substances with lower b.p.

As a kind of biomass resource, lignin is the only natural renewable resource that can provide abundant aromatic compounds, which is undoubtedly considered as the best candidate to produce value-added chems. by lignin depolymerization Thus, it is of great significance to develop approaches that are able to accommodate the complex structure of lignin. Herein, an efficient depolymerization method is implemented in methanol using a mesoporous solid superbase KF/γ-Al2O3 catalyst. Research shows that the depolymerization of lignin is not obvious below the critical temperature of methanol, and the conversion of lignin increases significantly above the critical temperature, which can reach 60.6% at 270°C. Phenols and methoxy-substituted monocyclic aromatic compounds are predominant in the liquid products acquired by gas chromatog./mass spectrometry. Furthermore, oligomers were analyzed by time-of-flight mass spectrometry equipped with electrospray ionization. It is found that the mol. mass of the oligomers varied between 200 and 600 Da, the degree of unsaturation is mainly 4 and 8 with 1-2 aromatic rings, and the carbon number is found to be within the range of 15-30. It is speculated that the oligomers are mainly monophenyl or biphenyl compounds containing branched chains.

《Chemical composition and larvicidal activity of flower extracts from Clitoria ternatea against Aedes (diptera: culicidae)》 was written by Ravindran, Darvin R.; Bharathithasan, Madhuri; Ramaiah, Patmani; Rasat, Mohd Sukhairi Mat; Rajendran, Dinesh; Srikumar, Shakila; Ishak, Intan H.; Said, Abd Rahman; Ravi, Rajiv; Amin, Mohamad Faiz Mohd. HPLC of Formula: 19444-84-9 And the article was included in Journal of Chemistry in 2020. The article conveys some information:

Mosquitoes have always been a human health threat; the major global health problems caused by them are malaria, dengue fever, yellow fever, and Zika as well as several other vector-borne outbreaks. The major problems in controlling these vectors borne diseases are related to resistance to eradication measures. Different classes of insecticides used for controlling public health have raised the concern of resistant problems with mosquitoes and environmental pollution caused by the control measures. Thus, a search for alternative natural compounds is necessary for solving the insecticidal resistance problem using pesticides in the larval stage of vector development as well as creating a chem.-free environment for a healthy society. Hence, the major focus of this study is to identify the larvicidal mechanisms, metabolite, antioxidants, and chem. compounds and elucidate their structures from C. ternatea flower and to test their efficacies against early 4th instar larvae of Aedes aegypti and Aedes albopictus. Clitoria ternatea flowers were collected from the garden of the Faculty of Medicine in International Quest University, Ipoh, Perak, and thence used for crude extraction Further on, the metabolite test, antioxidant test, and chromatog. techniques were conducted to identify the chem. composition of extracts and their chem. structures were identified using GCMS-QP2010 Ultra (Shimadzu). Next, the extracts were evaluated against the early 4th instar larvae of Aedes mosquito vectors following the WHO procedures for larval bioassays. The larvicidal activity of Clitoria ternatea flower extracts evidently affected the early 4th instar larvae of Aedes mosquito vectors. The highest larvicidal activity was observed against the early 4th instar larvae of Aedes aegypti with the LC50 and LC95 values of 1056 and 2491 mg/L, resp. Meanwhile, the larvae bioassay test for Aedes albopictus recorded the LC50 and LC95 values of 1425 and 2753 mg/L. Moreover, the results for nontarget organism test on guppy fish, Poecilia reticulata, showed no mortalities with flower extracts at 2500 mg/L, hence posing no toxic effects on fish. In this study, we have found a total of 16 chem. compounds and 6 chem. compounds have been reported to possess direct insecticidal, larvicidal, and pupicidal effects. Six chems. with insecticidal properties were found to be glycerin, 2-hydroxy-gamma-butyrolactone, neophytadiene, n-hexadecanoic acid, cis-vaccenic acid, and octadecanoic acid with a total of 28.7% efficacy. Clitoria ternatea flower extracts also showed different types of phenols such as anthocyanins, flavonoids, and tannins. Our findings showed that the crude extract of Clitoria ternatea flower bioactive mols. is effective and may be developed as biolarvicide for Aedes mosquito vector control. Furthermore, this study also provided a baseline understanding for future research work in the field of applications of Clitoria ternatea flower extracts for their long-term effects on human health such as a food additive, antioxidant, and cosmetic.

Kawamata, Yuki; Yoshikawa, Takuya; Koyama, Yoshihito; Ishimaru, Hiroya; Ohtsuki, Satoru; Fumoto, Eri; Sato, Shinya; Nakasaka, Yuta; Masuda, Takao published an article on January 31 ,2021. The article was titled 《Uniqueness of biphasic organosolv treatment of soft- and hardwood using water/1-butanol co-solvent》, and you may find the article in Industrial Crops and Products.Application of 19444-84-9 The information in the text is summarized as follows:

Biphasic organosolv treatment for soft- and hardwood using water/1-butanol was unique based on the correlation between liquid-phase states and solubility of the co-solvents when compared with a monophasic water/ethanol system. First, Pro II process simulator showed that water/1-butanol exhibited a biphasic system in the range of 1.6-19.0 mol/mol at a treatment temperature of 473 K. In addition, solubility of the co-solvents was evaluated using the Hildebrand solubility parameter (δ), which indicated that the biphasic system could simultaneously provide 28.5 and 42.0 MPa1/2 for the 1-butanol and water phase, resp. Each δ value appeared appropriate for lignin and hemicellulose dissolution because they were similar to those reported for lignin and a typical sugar. While hemicellulose could be removed by increasing water content in an organosolv of Japanese cedar sawdust, high lignin removal was achieved only under biphasic conditions. Carbon yield of each fraction (solid, 1-butanol-, and water-soluble fraction) and Py-GC/MS anal. revealed that lignin and hemicellulose could be recovered in the 1-butanol and water fractions, resp. The organosolv using Japanese cedar and willow was compared to the results when using monophasic water/ethanol. The results indicated that the co-solvent could not efficiently remove hemicellulose and lignin simultaneously because the monophasic system did not produce the level of solubility needed under the same conditions. In contrast, the biphasic water/1-butanol system achieved greater removal of hemicellulose and lignin compared to water/ethanol. The biphasic system was also applicable to separation of an industrial agricultural waste; sugarcane bagasse. Finally, the 2D-NMR spectra of 1-butanol-soluble lignin showed a trace amount of β-O-4 linkages in the lignin, indicating β-O-4 was cleaved via hydrolysis in the water phase during biphasic treatment.

Recommanded Product: 19444-84-9On October 15, 2021 ,《Co-hydrothermal carbonization of swine manure and cellulose: Influence of mutual interaction of intermediates on properties of the products》 was published in Science of the Total Environment. The article was written by Li, Qingyin; Lin, Haisheng; Zhang, Shu; Yuan, Xiangzhou; Gholizadeh, Mortaza; Wang, Yi; Xiang, Jun; Hu, Song; Hu, Xun. The article contains the following contents:

Co-hydrothermal carbonization (HTC) of livestock manure and biomass might improve the fuel properties of the hydrochar due to the high reactivity of the biomass-derived intermediates with the abundant oxygen-containing functionalities. However, the complicated compositions make it difficult to explicit the specific roles of the individual components of biomass played in the co-HTC process. In this study, cellulose was used for co-HTC with swine manure to investigate the influence on the properties of the hydrochar. The yield of hydrochar obtained from co-HTC reduced gradually with the cellulose proportion increased, and the solid yield was lower than the theor. value. This was because the cellulose-derived intermediates favored the stability of the fragments from hydrolysis of swine manure. The increased temperature resulted in the reduction of the hydrochar yield whereas the prolonged time enhanced the formation of solid product. The interaction of the co-HTC intermediates facilitated the formation of O-containing species, thus making the solid more oxygen- and hydrogen-rich with a higher volatility. In addition, the co-HTC affected the evolution of functionalities like -OH and C=O during the thermal treatment of the hydrochar and altered its morphol. by stuffing the pores from swine manure-derived solid with the microspheres from HTC of cellulose. The interaction of the varied intermediates also impacted the formation of amines, ketones, carboxylic acids, esters, aromatics and the polymeric products in distinct ways.
