Piper sarmentosum Roxb. (PS) and Piper cathayanum M. G. Gilbert & N. H. Xia (PC) are both listed as Traditional Chinese Medicine herbs. In this study, ultra-performance liquid chromatog. mass spectrometry (UPLC-MS/MS) was used to analyze secondary metabolites and metabolically profile the leaves, stems and roots in PS and PC. A total of 110 and 92 differential metabolites were shared from various organs of PS and PC, resp. Compared to the stems and roots of PS or PC, alkaloids and phenols in leaves of PS or PC accounted for 70% and 57% of the total alkaloids and phenols, resp. An anal. of enriched metabolic pathways demonstrated that L-tyrosine and 4-hydroxycinnamic acid in PS were directly involved in five and three metabolic pathways, which are related to the biosynthesis of isoquinoline alkaloids and phenol backbones, resp. The L-glutamic acid and oxoglutaric acid in PC were involved in seven and two metabolic pathways, resp. L-glutamic acid synthesizes heme, tropane, piperidine and pyridine alkaloids, and the type II polyketide backbone. Moreover, oxoglutaric acid generated via L-glutamic acid was mainly involved in the citrate cycle and played a fundamental role in determining these important metabolic processes. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Reference of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide

Zheng, Guihua; Yang, Yiyi; Deng, Linghui; Zhang, Ting; Zhu, Feiyun; Sun, Jing; Li, Shuangjiang; Feng, Xiaonan published an article in 2022, the title of the article was Pollution status and health impact assessment of antibiotics in environmental – and drinking water.Electric Literature of 144-80-9 And the article contains the following content:

The problem of antibiotics pollution in environmental water and drinking water has attracted the attention of environmental protection departments and all walks of life. At present, antibiotics have been widely detected in many water systems, and the concentration range is from ng/L to pg/L. In this paper, a method for the anal. of antibiotics in water by high performance liquid chromatog. tandem mass spectrometry (HPLC-MS/MS) was established. Then, the risk quotient (HQ) of antibiotics in wastewater treatment plant effluent and river water was calculated and studied. The results showed that some antibiotics did not cause direct ecol. risk. Finally, the health risk assessment of environmental water and drinking water was carried out. The results showed that the non carcinogenic risk caused by antibiotic pollution in the reservoir was far lower than the acceptable risk level, even far lower than the negligible risk level, indicating that the residues of these antibiotics in the drinking water would not pose significant non carcinogenic harm to human body. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Electric Literature of 144-80-9

On December 16, 2021, Shi, Wei; Tiwari, Surya P.; Thompson, Robert L.; Culp, Jeffrey T.; Hong, Lei; Hopkinson, David P.; Smith, Kathryn; Resnik, Kevin; Steckel, Janice A.; Siefert, Nicholas S. published an article.Recommanded Product: 1,3-Diphenylurea The title of the article was Computational Screening of Physical Solvents for CO2 Pre-combustion Capture. And the article contained the following:

A computational scheme was used to screen phys. solvents for CO2 pre-combustion capture by integrating the com. NIST database, an inhouse computational database, chem-informatics, and mol. modeling. A com. available screened hydrophobic solvent, di-Et sebacate, was identified from the screening with favorable phys. properties and promising absorption performance. The promising performance to use di-Et sebacate in CO2 pre-combustion capture has also been confirmed from experiments Water loading in di-Et sebacate is very low, and therefore, water is kept with H2 in the gas stream. The favorable CO2 interaction with di-Et sebacate and the intermediate solvent free volume fraction leads to both high CO2 solubility and high CO2/H2 solubility selectivity in di-Et sebacate. An inhouse NETL computational database was built to characterize CO2, H2, N2, and H2O interactions with 202 different chem. functional groups. It was found that 13% of the functional groups belong to the strong interaction category with the CO2 interaction energy between -15 and -21 kJ/mol; 62% of the functional groups interact intermediately with CO2 (-8 to -15 kJ/mol). The remaining 25% of functional groups interact weakly with CO2 (below -8 kJ/mol). In addition, calculations show that CO2 interactions with the functional groups are stronger than N2 and H2 interactions but are weaker than H2O interactions. The CO2 and H2O interactions with the same functional groups exhibit a very strong linear pos. correlation coefficient of 0.92. The relationship between CO2 and H2 gas solubilities and solvent fractional free volume (FFV) has been systematically studied for seven solvents at 298.2 K. A skewed bell-shaped relation was obtained between CO2 solubility and solvent FFV. When an organic compound has a d. approx. 10% lower than its d. at 298.2 K and 1 bar, it exhibits the highest CO2 loading at that specific solvent d. and FFV. Note that the solvent densities were varied using simulations, which are difficult to be obtained from the experiment In contrast, H2 solubility results exhibit an almost perfect pos. linear correlation with the solvent FFV. The theor. maximum and min. phys. CO2 solubilities in any organic compound at 298.2 K were estimated to be 11 and 0.4 mol/MPa L, resp. An examination of 182 exptl. CO2 phys. solubility data and 29 simulated CO2 phys. solubilities shows that all the CO2 phys. solubility data are within the maximum and min. with only a few exceptions. Finally, simulations suggest that in order to develop phys. solvents with both high CO2 solubility and high CO2/H2 solubility selectivity, the solvents should contain functional groups which are available to interact strongly with CO2 while minimizing FFV.

Wu, Huizhen; Zhou, Min; Xu, Jie; Wang, Jianmei; Tong, Jianying; Sun, Nabo; Qian, Mingrong published an article in 2022, the title of the article was Determining a wide range of antibiotics and pesticides in poultry feathers using selective accelerated solvent extraction-liquid chromatography-mass spectrometry.SDS of cas: 144-80-9 And the article contains the following content:

This study established a detection method based on accelerated solvent extraction-liquid chromatog.-mass spectrometry for determining residues of 3 chloramphenicols, 8 macrolides, 18 sulfonamides, 4 nitroimidazoles, 15 insecticides, and 22 fungicides in poultry feathers. The extraction solvent, methanol, was used for a static extraction time of 5 min, and repeated three times. Fifty milligrams of adsorbents C18/PSA (1 : 1, W/W) were added to the extraction cell to achieve simultaneous extraction and purification The extraction efficiency of three solvents, methanol, acetonitrile and Et acetate, was investigated. An orthogonal exptl. design was used to explore the optimal combination of extraction temperature, static extraction time, number of extraction cycles, and adsorbent ratio for accelerated solvent extraction After the optimal ratio was determined, the dosage of adsorbents was optimized. The extracted sample solution was concentrated by blowing nitrogen, redissolved, passed through a 0.22 渭m PTFE membrane filter, then injected for instrumental anal. The validation results showed that the recovery of the proposed method was 60.4-107.6%, the limit of detection 0.2-3.0 渭g kg-1, and the limit of quantification 0.5-8.3 渭g kg-1. This quant. multi-residue detection method was able to determine the residues of 70 target compounds in poultry feathers.

Bozkus, Tugba Nigar; Deger, Orhan; Yasar, Ahmet published an article in 2021, the title of the article was Chemical characterization of water and ethanolic extracts of Turkish propolis by HPLC-DAD and GC-MS.Name: N,N-Diethylacetamide And the article contains the following content:

This study aims to determine the qual. and quant. contents of Turkish propolis collected from various regions of Turkey using high-performance liquid chromatog. with the diode-array detector (HPLC-DAD) and gas chromatog.-mass spectrometry (GC-MS) in water and ethanolic extracts In HPLC-DAD analyses, it was determined that water extract of Turkish propolis contains phenolic acids such as caffeic acid (204.00 渭g/mL), trans-cinnamic, chlorogenic, and caffeoylquinic acids, responsible for its antioxidant activity; whereas, the ethanolic extract of Turkish propolis contains chrysin (641.33 渭g/mL), caffeic acid phenethyl ester (630.67 渭g/mL), pinocembrin (572.67 渭g/mL), galangin (534.11 渭g/mL), naringenin (372.39 渭g/mL), and also kaempferol, trans-cinnamic acid, caffeic acid, myricetin, and quercetin. GC-MS analyses showed that ethanolic extract of propolis contains caffeic acid by Rtx-1 column and the water extract of propolis contains quinic acid and ferulic acid by Rtx-5ms column. Various sugar derivatives were detected by both columns in water and ethanolic extracts of Turkish propolis. HPLC-DAD can be considered as a more effective method than GC-MS for the chem. characterization of propolis. Water extract of Turkish propolis can be a good source of raw materials for various sectors, as it is both cheap and has less health risk than ethanolic extract, and is suitable for human use. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Name: N,N-Diethylacetamide
