Insyani, Rizki published the artcileImproved hydrodeoxygenation of lignin-derived oxygenates and biomass pyrolysis oil into hydrocarbon fuels using titania-supported nickel phosphide catalysts, COA of Formula: C9H10O4, the publication is Energy Conversion and Management (2022), 115822, database is CAplus.

Biomass pyrolysis oil is a potentially essential renewable energy source that can serve as an alternative to petroleum-based fuels and chems. In this study, biomass pyrolysis oil was converted into petroleum-like deoxygenated hydrocarbons via catalytic hydrodeoxygenation using a titania-supported nickel phosphide catalyst. The phosphor precursor was added to several transition metals, including nickel, cobalt, copper, and iron, supported on titania. The formation of isolated nickel phosphide particles, which were active for complete hydrodeoxygenation, was confirmed by the characterization of prepared catalysts. As a model reactant of biomass pyrolysis oil, a mixture of alkyl-methoxyphenol compounds was hydrodeoxygenated to produce completely deoxygenated compounds, generating an 87% yield of cycloalkanes at 300 °C and 4 MPa H2 for a reaction time of 2 h. The hydrodeoxygenation of biomass pyrolysis oil also generated a 37.4% yield of hydrocarbon fuels. The high hydrodeoxygenation activity can be attributed to the synergy between the hydrogenating metals and the acid sites, which can be improved by electron transfer from a slightly cationic nickel to a slightly anionic phosphor. Furthermore, the addition of phosphor improved the formation of highly dispersed nickel particles, increasing the quantity of hydrogen-adsorbing surface metals. The observations in this study indicate that the efficient conversion of lignocellulose-derivatives into chems. and fuels can be achieved using modified non-precious transition metal catalysts.

Zou, Zidan published the artcileCore shell hetero-structured SiO₂@Ni/SiO₂ catalyst for efficient aqueous-phase hydrogenation of bio-derived unsaturated compounds, SDS of cas: 134-96-3, the publication is Fuel (2022), 123694, database is CAplus.

Silica is one of the most referenced materials for the preparation of heterogeneous metal catalysts. However, silica spheres with smooth surfaces have difficulty encapsulating active metals due to their small surface area and the presence of only a handful of silicon hydroxyl groups on the surface. In this work, the silica sphere has been first consciously transformed into a hierarchical SiO₂@silicate structure, and then the core-shell hetero-structured SiO₂@Ni/SiO₂ catalyst can be tactfully obtained by reducing treatment. The core-shell catalyst is composed of a rigid core (SiO2) and a rough shell (Ni NPs highly disperse on nanosheet SiO₂), which are carefully verified by X-ray diffraction (XRD), transmission electron microscope (TEM), field scanning electron microscope (FESEM), H₂-TPR/TPD and XPS. The derived SiO₂@Ni/SiO₂ catalyst can selectively hydrogenate vanillin in the aqueous phase at near-room temperature (40 °C) and low hydrogen pressure (2 MPa H₂), and the conversion of vanillin can be up to 99%. The preparation method of the SiO₂@Ni/SiO₂ catalyst is simple and can be amplified to a large scale at a low price, thus can be adopted to convert bio-derived unsaturated compounds in an economical and eco-friendly way.

Tan, Ming published the artcileRoasting treatments affect physicochemical, aroma and nutritional quality of strong fragrant rapeseed oil, Related Products of ethers-buliding-blocks, the publication is Journal of Food Composition and Analysis (2022), 104648, database is CAplus.

The strong fragrant rapeseed oil (SFRO) attracts the growing interest in China due to its fragrant flavor, attractive color, and phys. and oxidative stability. It is usually produced with simple processes including rapeseed roasting, mech. pressing, and degumming with hot water (80-90°C). To produce SFROs with high quality and nutritional contents, the seed roasting parameters including temperature up to 220°C and time ranging from 10 min to 30 min were investigated. Results showed that 20-min roasting at temperature 160°C resulted in the highest oil extraction yield of 33.20% with the lowest water content of 0.121%. The produced SFRO had the roasted, nutty and soft tastes with the maximum overall score, the highest total tocopherol and sterol contents of 789.73 mg/kg and 4582.80 mg/kg, resp., and high CoQ10 content of 65.57 mg/kg. Over-roasting at roasting temperature of over 180°C and time of over 30 min led to the high Lovibond red readings, off-flavors, and increased concentrations of high saturated fatty acids and Benzo[a]pyrene (BaP). Our findings would provide a reference to produce SFROs with the highest extraction yield and nutrient contents, acceptable physicochem. properties, optimal profile of the fatty acids and the key aroma compounds, and relatively-low BaP concentration

Jimenez-Sanchez, Maria published the artcileThe impact of ultrasound, micro-oxygenation and oak wood type on the phenolic and volatile composition of a Tempranillo red wine, Computed Properties of 134-96-3, the publication is LWT–Food Science and Technology (2022), 113618, database is CAplus.

The accelerated ageing of a Tempranillo red wine has been studied at pilot scale through the combined application of ultrasound, micro-oxygenation and different oak wood type chips (American, French and Spanish). The phenolic and volatile content of the aged samples and their sensory profiles have been determined The wine samples that had been aged using micro-oxygenation, French or American oak chips, and ultrasound revealed to be similar in terms of polyphenols to those wines that had been aged without implementing this last accelerating technique. Ageing time, with a high extraction kinetics, was the most significant variable with regard to their polyphenol content. In terms of volatiles, Spanish and French oak wood wine samples showed a similar behavior closely associated to ageing time, while American oak wood achieved a rather low enrichment in volatile constituents, resulting in a poor sensory profile of the final wines, which was particularly poor in the case of ultrasound aged wines.

Ruan, Jing-Ya published the artcileStructural characterization of phenolic constituents from the rhizome of Imperata cylindrica var. major and their anti-inflammatory activity, HPLC of Formula: 134-96-3, the publication is Phytochemistry (Elsevier) (2022), 113076, database is CAplus and MEDLINE.

As one of raw materials, the rhizome of Imperata cylindrica var. major (Nees) C. E. Hubb. is used in kinds of preparations curing inflammation related diseases, while its effective substances are not yet clear. In this paper, its chem. constituents and their anti-inflammatory activities were investigated. As results, ten compounds, named as imperphenoside A (1), imperphenols B (2) and C (3), imperphenosides D-F (4-6), and imperlignanosides A-D (7-10), along with previously reported thirty-seven known ones (11-47) were obtained from it. Their structures were ascertained basing on the extensive spectroscopic methods and electronic CD data anal. Meanwhile, compounds 4, 11, 12, 24, 27, 31, 32, 37, 43, 45, and 47 exhibited nitric oxide inhibitory effects in concentration dependent at 3, 10, and 30 μM on lipopolysaccharides induced RAW 264.7 cells. Moreover, the western blot anal. indicated that compounds 4, 11, 43, and 47 could restrain the phosphorylation of nuclear factor kappa-B kinase to down-regulate the protein expression of inflammatory cytokines such as inducible nitric oxide synthase, interleukin-6 and tumor necrosis factor-α. In conclusion, they might play the anti-inflammatory effects through regulating NF-κB signaling pathway.

Sun, Guodong published the artcileOrganic matter biomarker and ¹³C NMR characteristics of soil and sediment standard reference materials from China, Formula: C9H10O4, the publication is Science of the Total Environment (2022), 155661, database is CAplus and MEDLINE.

Soil and sediment organic matter (OM) in terrestrial environments represent two critical organic carbon pools on Earth and are likely subject to distinct degrees of oxidation and modification. However, few studies have identified critical mol.-level characteristics that differentiate soil and sediment OM from various climate zones. Using biomarkers and solid-state ¹³C NMR (NMR) spectroscopy analyses, we studied the OM characteristics of 11 soil and 7 sediment standard reference materials (SRMs) originating from various geog. locations in China. Results showed significantly higher concentrations of lignin phenols in sediment OM than in soil OM, which may result from protection by higher contents of CaO and less microbial degradation in sediments. Nevertheless, the relative abundances of solvent-extractable lipids (alkanes, alkanols, and alkanoic acids) and ester-bound cutin and suberin biomarkers did not differ significantly between soil and sediment SRMs. The concentrations of lignin biomarkers decreased with increasing weathering degree of the soil, while cutin biomarkers increased with mean annual temperature and precipitation This phenomenon was not observed in sediment SRMs. This study reveals the distinct OM characteristics between Chinese soil and sediment SRMs and provides fundamental data for future studies to link OM characteristics and functions.

Oikonomou, Adriana published the artcileDefence against Bremia lactucae conferred by the resistance gene Dm7 in lettuce is broken by treatment with dichloroisonicotinic acid, Name: 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Plant Pathology (2022), 71(3), 611-620, database is CAplus.

The effect of inducers of systemic acquired resistance, dichloroisonicotinic acid (DCINA) and acibenzolar-S-Me (BION), on compatible interactions between Bremia lactucae and lettuce were examined using a detached cotyledon infection assay. Treatment with both activators caused a reduction in sporulation on susceptible cultivars Cobham Green challenged with isolate CL9W and Diana inoculated with isolate Tv, with DCINA being more effective than BION on an equimolar basis. Unexpectedly, treatment with both compounds suppressed the resistance conferred by the Dm7 gene in cv. Diana challenged by isolate CL9W (A7). The frequency of sporulation was greatly increased by DCINA in the incompatible interaction. The suppression of defense was associated with a delay in the onset of the Dm7-based hypersensitive reaction as indicated by the extended viability of penetrated epidermal cells, and reductions in both the accumulation of the phytoalexin lettucenin A and the deposition of autofluorescent phenolics such as syringaldehyde on plant and oomycete cell walls. The anal. of DCINA homologues indicated that 2-chloroisonicotinic acid was as effective as the dichloro-derivative in suppressing resistance in cv. Diana, whereas the absence of the carboxyl group rendered 2,6-dichloropyridine inactive. Infection of cotyledons by Botrytis cinerea was also found to be enhanced by DCINA treatment. Based on our results, we discuss the possibility that DCINA reduces Dm7 transcription through an epigenetic mechanism, as is supported by bioinformatic analyses of the resistance gene, and that it suppresses jasmonate-dependent resistance to B. cinerea.

Rozas, Robinson published the artcileSolvent effects on the molecular structure of isolated lignins of Eucalyptus nitens wood and oxidative depolymerization to phenolic chemicals, Synthetic Route of 134-96-3, the publication is Polymer Degradation and Stability (2022), 109973, database is CAplus.

The aim of the present work was to study the effect of a solvent/water mixture on the structural characteristics of extracted lignin from Eucalyptus nitens, and to relate the functional groups and inter unit linkages present in the lignin with the distribution of phenolic compounds obtained after its alk. oxidation The high content of β-O-4′ substructures linked to a S unit in organosolv lignins of E. nitens lignin could be linked to the high yield of syringaldehyde in its alk. oxidation Kraft lignin oxidation gives rise to lower content of syringaldehyde when compared with organosolv lignins. This might be due to the higher proportion of condensed structures, mainly β-β’ (∼42%) and spirodienone (∼14%). Fukui functions showed that the regions with higher probability for an electrophilic attack on lignin would be located on Ph rings and on the phenolic -OH group (benzylic position), whereas nucleophilic attacks in some cases were located over the double bond and ring. This work contributed to a better description of the proposed oxidative depolymerization mechanisms.

Batsch) extracts and an evaluation of their antidiabetic, antioxidant, and antibacterial activities, Related Products of ethers-buliding-blocks, the publication is South African Journal of Botany (2022), 636-645, database is CAplus.

Peaches contain high amounts of polyphenol compounds The consumption of peaches gives protection against various conditions such as obesity, diabetes, cardiovascular and bacterial diseases, and inflammation. The present study aimed to examine the phytochem. compounds and the antioxidant, antibacterial, anti-α-glucosidase, and anti-α-amylase activities of the different extracts (methanol, ethanol, and hexane) of fresh red peach collected from the Mersin province in Turkey. In this study, chem. compositions of methanol and ethanol extracts prepared from peach pulp were studied by using liquid chromatog.-mass spectrometry (LC-MS/MS). Thirteen metabolites: quinic acid, fumaric acid, aconitic acid, protocatechuic acid, salicylic acid, chlorogenic acid, rutin, isoquercitrin, hesperidin, astragalin, nicotiflorin, quercetin, and amentoflavone, were identified in ethanol extracts and also these phenolic compounds, excluding salicylic acid, were identified in the methanol extract The ethanol extract showed the most activity in all enzyme inhibition and in antibacterial and antioxidative activity assays, which is mainly due to its rich phenolic content. The most dominant compounds determined in ethanol extract were quinic acid, chlorogenic acid, fumaric acid, and isoquercitrin resp. According to the results of this study, ethanol extract in particular is a potential ingredient to be used in food-derived antidiabetic and antibacterial formulations.

Samir Ali, Sameh published the artcileExploring the potential of a newly constructed manganese peroxidase-producing yeast consortium for tolerating lignin degradation inhibitors while simultaneously decolorizing and detoxifying textile azo dye wastewater, Formula: C9H10O4, the publication is Bioresource Technology (2022), 126861, database is CAplus and MEDLINE.

MnP-YC4, a newly constructed manganese peroxidase-producing yeast consortium, has been developed to withstand lignin degradation inhibitors while degrading and detoxifying azo dye. MnP-YC4 tolerance to major biomass-derived inhibitors was promising. MnP induced by lignin was found to be highly related to dye decolorization by MnP-YC4. Simulated azo dye-containing wastewater supplemented with a lignin co-substrate (3,5-Dimethoxy-4-hydroxybenzaldehyde) decolorized up to 100, 91, and 76% at final concentrations of 20, 40, and 60%, resp. MnP-YC4 effectively decolorized the real textile wastewater sample, reaching up to 91.4%, and the COD value decreased significantly during the decolorization, reaching 7160 mg/l within 7 days. A possible dye biodegradation pathway was proposed based on the degradation products identified by UV-vis, FTIR, GC/MS, and HPLC techniques, beginning with azo bond cleavage and eventually mineralized to CO₂ and H₂O. When compared to the phytotoxic original dye, the phytotoxicity of MnP-YC4 treated dye-containing wastewater samples confirmed the nontoxic nature.
