Agarwal, Charu published the artcileLow-frequency, green sonoextraction of antioxidants from tree barks of Hungarian woodlands for potential food applications, Quality Control of 30931-67-0, the publication is Chemical Engineering and Processing (2021), 108221, database is CAplus.

The present work evaluates and compares the antioxidant capacities of bioactive constituents in the barks of ten common wood species from Hungary (Quercus rubra, Prunus serotina, Quercus robur, Betula pendula, Fraxinus excelsior, Robinia pseudoacacia, Carpinus betulus, Picea abies, Alnus glutinosa, Pinus sylvestris). Low-frequency ultrasound was used for intensification of extraction from the bark to obtain extracts rich in polyphenolic antioxidants with potential applications in the food industry. The extractions were carried out in different aqueous organic solvents- ethanol 80% and acetone 80% at optimized conditions. The overall antioxidant capacity of the extracts was estimated by the combined evaluation of Folin-Ciocalteu total phenol content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric reducing ability of plasma (FRAP) assays using a scoring system. Aqueous ethanol had better extraction efficiency than aqueous acetone as a solvent medium. Of all the investigated species, Quercus robur showed the maximum antioxidant capacity with TPC of 105.88 ± 17.75 mg GAE/g dw, DPPH (IC50) of 1.90 ± 0.10μg/mL, ABTS of 437.09 ± 36.22 mg TE/g dw and FRAP of 102.62 ± 8.69 mg AAE/g dw. The polyphenolic characterization of Quercus robur, Robinia pseudoacacia and Fraxinus excelsior was done by liquid chromatog./tandem mass spectrometry.

Tang, Yue published the artcileA facile colorimetric sensor for ultrasensitive and selective detection of Lead(II) in environmental and biological samples based on intrinsic peroxidase-mimic activity of WS2 nanosheets, Computed Properties of 30931-67-0, the publication is Analytica Chimica Acta (2020), 115-125, database is CAplus and MEDLINE.

Two-dimensional layered WS2 nanosheets with rich active edge exhibit intrinsic peroxidase-mimic activity, which make them an ideal material for sensor design. However, there is still lack of research on the catalysis and regulation mechanisms of the layered WS2 nanosheets as well as their application in the detection of hazardous substances. Herein, the regulatory effect of Pb(II) on the peroxidase-mimic activity of the layered WS2 nanosheets was firstly investigated, which enable us to construct a novel and facile colorimetric sensor for ultrasensitive and selective detection of Pb(II). To improve the performance of colorimetric sensor, some important parameters like buffer conditions, substrates and temperature have been investigated. Under the optimal conditions, the catalytic kinetics of layered WS2 nanosheets were extensively investigated. The peroxidase-mimic catalytic reaction was proved to be the “ping pong” mechanism, and the regulatory effect of Pb(II) on layered WS2 nanosheets was agreed with noncompetitive inhibition. The absorbance variation of colorimetric sensor is proportionally related to the concentration of heavy metals, which enable us to easily distinguish whether Pb(II) exceeds the permissible level in less than 20 min even by the naked eyes. The limit of detection (LOD) and the limit of quantification (LOQ) of the proposed colorimetric sensor for Pb(II) were determined as low as 4μg L-1 and 13.3μg L-1, and displays excellent selectivity against other competitive metal ions. Moreover, the further studies also validate the applicability of colorimetric sensor in several actual samples, indicating that our strategy may has prospective applications for Pb(II) detection in environment and biol. samples.

Wang, Rongrong published the artcileAnionic-Surfactant-Stabilized Hydrophobic Ionic-Liquid-Based Bicontinuous Microemulsion as a Medium for Enzymatic Oxidative Polymerization of Aniline, HPLC of Formula: 30931-67-0, the publication is ACS Omega (2021), 6(31), 20699-20709, database is CAplus and MEDLINE.

The hydrophobic ionic liquid [C8mim][PF6] (1-octyl-3-methylimidazolium hexafluorophosphate)-based bicontinuous microemulsion stabilized by the anionic surfactant [C4mim][AOT] (1-butyl-3-methylimidazolium bis(2-ethylhexyl) sulfosuccinate) was first tried as a medium for horseradish peroxidase (HRP)-triggered oxidative polymerization of aniline. The effects of the mass ratio of [C8mim][PF6]-to-water (α), the mass fraction of [C4mim][AOT] in the total mixture (γ), and temperature (T) on the enzymic polymerization were investigated using UV-vis-NIR absorption, ESR, and small-angle X-ray scattering spectroscopy techniques. The bicontinuous microemulsion is demonstrated to play a template role in the biosynthesis of polyaniline (PANI). The conductivity of the resulting PANI depends on the microemulsion microstructure and the microstructure- and T-dependent catalytic properties of the solubilized HRP. With the increase in α, the conductivity of the synthesized PANI decreases due to the increase in the template curvature (decrease of the microdomain size) and the decrease in the activity and stability of HRP. Compared with α, γ has little effect on the microdomain size of the template; so, the γ-dependent change in the conductivity of PANI is mainly caused by the changes of the microstructure-dependent activity and stability of HRP. Over the range of 20-35°C, T has little effect on the microdomain size, but it greatly changes the activity and stability of HRP. With the increase in T, the activity of HRP increases steadily, but its stability decreases significantly, which should be one of the reasons why the conductivity of PANI decreases with increasing T. In conclusion, lower values of α, γ, and T are favorable for the biosynthesis of conductive PANI. The present study not only deepens the insight into the role of the template in the process of PANI synthesis, but also opens up a green new way for the biosynthesis of the conducting polymer.

Nam, Jeongmin published the artcileEffect of crosslinkable bacterial cellulose nanocrystals on the physicochemical properties of silk sericin films, Product Details of C18H24N6O6S4, the publication is Polymer Testing (2021), 107161, database is CAplus.

The manufacture of eco-friendly cocoon silk-derived sericin films increases the availability of sericulture resources and the interest in expanding the range of the potential applications of sericin-based materials. However, the brittleness and weak tensile properties of sericin and its vulnerability to moist environments have limited its use. To overcome these two shortcomings of sericin, a functionalized bacterial cellulose-derived nanocrystal (average diameter: 25.4 nm) capable of phys. strengthening and chem. crosslinking on existing sericin films was prepared The improvement of the optical, physicochem., and mech. properties of the sericin film was observed through the dialdehyde bacterial cellulose nanocrystals (D-CNCs) incorporated into the silk sericin (SS) matrix. The phys. reinforcing effect of the D-CNCs on the SS films enhances the mech. properties of the films. Simultaneously, the chem. crosslinking reaction of D-CNCs develops the UV-blocking, water-resistant, and antioxidant properties of the films. The simultaneous fabrication, phys. reinforcement, and chem. crosslinking of the SS/D-CNCs biocomposite film produced using an aqueous solution will provide information on the functionalization and performance improvement of water-soluble biopolymeric materials, especially hydrophilic protein resources.

In previous research works, we have described the production of 7 kDa F5 peptide after a hydrolysis of the white shrimp, Metapenaeus monoceros (Fabricius, 1798) byproduct, using a serine alk. protease (SPVP) purified from Aeribacillus pallidus strain VP3. The present study aims to explore the antioxidative potentials of F5 peptide by both in vitro and in vivo assays. The anti-biofilm activity was performed, showing 50% inhibition at 2μg/mL, 3μg/mL, 19μg/mL, and 45μg/mL for Staphylococcus aureus, Escherichia coli, Bacillus cereus, and Pseudomonas aeruginosa, resp. Consistently, the antioxidative capacity was tested in vitro against 2,2′-azino-bis-(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) cation radical, β-caroten-linoleic acid bleaching, chelating capacity of ferrous ion, and ferric reducing power assays. The cytotoxic effects of F5 peptide on the Human embryonic kidney HEK293 cells were subsequently tested. Remarkably, the F5 peptide was able to improve significantly HEK293 cell viability. To further assess this bioactivity, an in vivo study was performed on adult mice models. The animals were divided into three groups: controls, 100 mg and 200 mg of F5/kg per bodyweight. Indeed, the F5 peptide could prevent the lipid and protein oxidation damage in kidney cells, improving the antioxidative enzymic and non-enzymic capacities.

Chehab, Rana; Coulomb, Bruno; Boudenne, Jean-Luc; Robert-Peillard, Fabien published an article on January 15 ,2020. The article was titled 《Development of an automated system for the analysis of inorganic chloramines in swimming pools via multi-syringe chromatography and photometric detection with ABTS》, and you may find the article in Talanta.Reference of ABTS Diammonium The information in the text is summarized as follows:

Inorganic chloramines are disinfection byproducts resulting from the unwanted reaction between chlorine used as disinfectant in swimming pools and nitrogenous compounds brought by bathers. This parameter (total chloramines or combined chlorine) is currently measured on site by a colorimetric method that does not allow to measure only inorganic chloramines. In this paper, a multi-syringe chromatog. system combined with a post column derivatization is applied for the first time for the specific detection of the three individual inorganic chloramines (monochloramine, dichloramine and trichloramine). These latter ones are separated using a low-pressure monolithic C18 column, and sep. detected after a post-column reaction with the chromogenic reagent ABTS (2,2′-azino-bis-(3-ethyl-benzothiazoline)-6-sulfonic acid-diammonium salt). Development of two ABTS reagents provides discrimination of chlorine and monochloramine that are not separated on the column. Optimization of the exptl. conditions enables determination of inorganic chloramines with very good detection limits (around 10 μg eq.Cl2 L-1) without interferences from other chlorinated compounds such as organic chloramines or free available chlorine. The validation of the whole procedure has been successfully applied to real swimming pools samples. In the experiment, the researchers used ABTS Diammonium(cas: 30931-67-0Reference of ABTS Diammonium)

The phenolic content and antioxidant potential of malting barley are important in brewing. The objective of our study was to investigate the effects of barley genotype, growing environment, and malting conditions on the total phenolic content and antioxidant activities of malting barley grown in North America. Eight barley cultivars grown at three locations over three years were used. For the malting study, a single barley cultivar, separated into different kernel size fractions, was germinated for various periods of time and then processed by kilning or freeze-drying. Total phenolic content (TPC) and some of the antioxidant activities, including DPPH, ABTS, and superoxide anion radical scavenging activities, reducing power, and iron (II) chelating activity, were significantly impacted by the barley genotype, growth environment, and their interactions. The TPC and most antioxidant activities were also influenced by malting conditions and were generally higher in the malted barleys of the thin kernel size fraction, four-day germination, and in samples processed by kilning, when compared to the plumper kernel size fractions, one and two days of germination, and freeze-dried samples, resp. There were interactions between malting parameters, and stepwise regression anal. was used to suggest the contribution of each parameter to the TPC and antioxidant activities.

The objectives of this research were to determine the sugar compositions, polyphenol contents and antioxidant effects of non-centrifugal sugars (NCS) of different sugarcane varieties. The polyphenols contents and compounds of nine NCSs obtained from the juices of different sugarcane varieties clarified with a 50 nm ceramic membrane (M-NCSs) were measured via ultraperformance liquid chromatog.-mass spectrometry (UPLC-MS). Their antioxidant activities were investigated via 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, 2, 2′-azino-bis-(3-Et benzothia-zoline-6-sulfonic acid) (ABTS) assay, β-carotene-linoleate assays, and ferrous and cupric ion chelating assays. Results showed that the phenolic compound with the highest content was gallic acid, and all samples were abundant in phenolics, including flavonoids, with high antioxidative activities. The content of phenolics and flavonoids, ranged from 17.24 to 21.14 mg/mL and from 203.55 to 350.37μg/mL, resp. Among these M-NCSs, Funong 41 (G) genotype had the best DPPH free radical scavenging activity. The GUC 23-2 (A1) genotype showed the best ABTS free radical scavenging activity. β-Carotene-linoleate assays revealed that the 15-6013 (B2) genotype exhibited the best antioxidant activity. The Guitang 42 (E) genotype displayed the best ferrous ion chelating activity. The Zhongzhe 9 (F) genotype presented the best cupric ion chelating activity.
