Plant polyphenols are secondary metabolites that play a crucial role in plant resistance to environmental stressors,and exhibit a variety of health benefits for the human body.In recent years,there has been an increasing focus on the health effects of plant polyphenols,including tea polyphenols,and curcumin.These compounds possess antimicrobial and anti-inflammatory properties,as well as the ability to regulate Reduction-Oxidation(REDOX)processes and metabolism.However,the instability of the phenolic hydroxyl structure in plant polyphenols results in low bioavailability,which limits their application in health food and biomedicine.Advances in assembly chemistry and nanotechnology have established a foundation for the construction of stable polyphenol biomaterials,thereby enhancing their biological effects.This review focuses on the development of plant polyphenol-based biomaterials,including selfassembled polyphenol nanoparticles,polyphenol-based eutectic systems,polyphenol hydrogels,and polyphenol chitosan,for applications in antimicrobial activity,drug delivery,and disease treatment.The aim is to explore the latest research advancements in plant polyphenol biomaterials and to promote the application of these natural compounds in the fields of food and biomedicine. 展开更多

Objective Exposure to mixtures of environmental chemicals may influence asthma outcomes;however,the evidence remains equivocal.This study aimed to assess the association between mixed exposure to phenols and parabens and asthma outcomes in adults and to explore the mediating role of body mass index(BMI).Methods Based on data from the National Health and Nutrition Examination Survey(NHANES,2013–2016),this study used multivariate generalized linear regression and weighted quantile sum(WQS)regression models to evaluate the associations between individual and joint exposure to phenols and parabens and asthma outcomes.These associations were further analyzed and stratified according to age and BMI.A mediation effect analysis was used to assess the role of BMI in this association.Results This study included 2,556 adults,of whom 400(15.7%)were diagnosed with asthma.After adjusting for all covariates,a significant positive correlation was observed between the chemical mixture and asthma,with an odds ratio of 1.33(95%confidence interval,1.06–1.68).Among the eight phenols and parabens,bisphenol F(BPF),propylparaben(PrP),and bisphenol S(BPS)were the major contributors.Additionally,BMI mediated 15.5%of the association between BPF exposure and asthma.Conclusion In this cross-sectional study,mixed exposure to phenols and parabens was significantly associated with asthma outcomes,with BPF,PrP,and BPS identified as the primary contributing chemicals.This study provides valuable insights into the association between mixed chemical exposure and asthma as well as potential control pathways. 展开更多

Phenolic compounds are vital chemicals that can be converted into high-density jet fuel components, such as aromatic hydrocarbons or cycloalkanes. Pyrolysis of biomass waste for producing high-value phenolic compounds offers a sustainable approach to waste management and energy conversion. While N/O-doped biochar has demonstrated potential in enhancing phenolics production, its application faces challenges such as complex preparation, high activation temperatures, and unclear catalytic mechanisms. This study addresses these issues by developing a single-step sodium amide(NaNH2) activation method at mild temperatures(<500℃) to produce N/O-doped biochar with optimized catalytic properties. Characterization identified graphitic-N(–GN) and oxidized-N(–ON) configurations, along with aldehyde-O(–CHO) and carboxyl-O(–COOH) groups, as key active sites that enhanced catalytic performance. Experimentally, the N/O-doped biochar achieved a phenolics yield of 57.87% at an activation temperature of 400℃, representing a 19.18% increase over non-catalytic condition. Density functional theory(DFT)calculations further elucidated the role of N and O groups, showing that –GN and –ON in N groups, as well as –CHO and –COOH in O groups,lowered energy barriers in radical-induced demethoxylation, thereby promoting phenolic product formation. Machine learning analysis identified nucleophilicity and local softness as critical descriptors, indicating that these configurations effectively modulated electron density at active sites. These findings provide a comprehensive mechanistic understanding of how specific N and O functional groups in biochar enhance catalytic efficiency in targeted phenolic production. 展开更多

Grape peel,as the by-product of grape wine,is rich in phenolic and proanthocyanidins.Obesity has become a serious global public health problem and supplementation of grape peel phenolics(GPP)may be an effective intervention method.From a dietary nutrition perspective,this study aims to investigate the effects of GPP on improving intestinal barrier function in high-fat diet-treated mice,and further explore the potential mechanism.The results showed that GPP supplementation obviously reduced body weight of mice,increased the abundance of beneficial bacteria(Akkermansia,g_Lachnospiraceae_NK4A136_group,Bacteroidetes and g_norank_f_Muribaculaceae),reduced the relative abundance of harmful bacteria(g_Coriobacteriaceae_UCG-002,g_Dubosiella and Romboutsia).Meanwhile,GPP could alleviate colonic barrier inflammation,facilitate the production of short-chain fatty acids and secondary bile acids,increase the mRNA and protein expression levels of intestinal tight junction proteins,and protect intestinal barrier integrity,especially in the LGPP group(100 mg/kg·day GPP).Kyoto Encyclopedia of Genes and Genomes analysis on fecal metabolism indicated that GPP could effectively alleviate intestinal imbalance caused by obesity through targeting multiple shared pathways.Bile secretion and arachidonic acid are the key differential metabolic pathways,and 14 key differential metabolites were identified.In conclusion,GPP supplementation has the potential to alleviate obesity by regulating gut microbiota,improving gut barrier integrity,and modulating the related metabolites. 展开更多

During the casting process,no-bake resin-bonded sand molds and cores rapidly heat up upon contact with high-temperature molten metal,causing dramatic changes in the resin binder system and a significant deterioration in mechanical properties,which subsequently leads to casting defects.To reveal the mechanism behind the evolution of high-temperature performance,the effects of resin content,base sand type,and particle size on the compressive strength of alkaline phenolic no-bake resin-bonded sand at temperatures ranging from 600℃ to 1,000℃ were investigated.The results show that the temperature range of 600-800℃ represents the primary stage of strength loss,corresponding to intense resin decomposition.Meanwhile,structural reorganization of the carbon skeleton above 900℃ can lead to a partial recovery of strength.This study provides key data and theoretical support for understanding the high-temperature mechanical behavior of resin-bonded sand and its relationship with casting defects. 展开更多

The sustainable sourcing of novel bioactive compounds from natural sources is crucial to the success of the pharmaceutical,food,and cosmetics industries.Iris bucharica Foster(syn.Juno bucharica(Foster)Vved.)is a promising source of novel bioactive molecules,particularly phenolic compounds,which are renowned for their antioxidant properties.In this study,we developed a reliable HPLC-UV-DAD method to identify and quantify phenolic compounds in the leaves and bulbs of I.bucharica,establishing the first set of quality control markers for this species.A total of 21 phenolic compounds were identified in the leaves,with flavonoids isoorientin,guaijaverin,hyperoside,and cosmosiin,the isoflavonoid biochanin A,and the simple phenolic ferulic acid being the most prominent.In comparison,14 compounds were identified in the bulbs,primarily isoflavonoids,including tectoridin and germanaism B,and flavonoid apigenin.The leaves extracts exhibited significant antioxidant activity,whereas the anti-allergic and anti-inflammatory effects were mild.These findings highlight I.bucharica as a sustainable source of bioactive compounds with potential industrial applications.However,further studies are needed to evaluate bioavailability and in vivo efficacy,as well as to optimise extraction methods to realize its industrial potential fully. 展开更多

The extraction of phenol was conducted in the straight,helical and in-plane spiral microchannels using tributyl phosphate,methyltri-n-octylammonium chloride and 1-butyl-3-methylimidazolium hexafluorophosphate in kerosene,respectively.The results indicated that initial phenol concentration had little effect on phenol extraction efficiency but led to a near-linear increase in space-time yield of phenol.The phenol extraction efficiency initially rose sharply with capillary length before stabilizing,whereas space-time yield of phenol decreased continuously with increasing capillary length.Both extraction efficiency and space-time yield of phenol declined with increasing capillary inner diameter.In the straight microchannel,the phenol extraction efficiency increased with overall volumetric flow rate before leveling off,while in the in-plane spiral microchannel,it decreased with increasing flow rate.The space-time yields in both straight and in-plane spiral microchannels increased rapidly with rising overall volumetric flow rate.The extraction efficiency and space-time yield of phenol decreased with increasing helical diameter and pitch.Horizontal placement of the helical microchannel yielded higher extraction efficiency and space-time yield of phenol compared to vertical placement.Increasing the volume fraction of extractant in the extractant phase improved both extraction efficiency and spacetime yield of phenol.Under optimal conditions,phenol extraction efficiencies in all three microchannels exceeded 99.8%.Among phenol-containing wastewater with identical flow rates and concentrations,the in-plane spiral microchannel demonstrated superior phenol extraction performance compared to the other two microchannel types.The improvement of extraction efficiency and spacetime yield of phenol were realized through both reduction in microchannel dimensions and increase in the curvature of the microchannel. 展开更多

Phenolic acid metabolites play important physiological roles,and many genetic loci affecting phenolic acid metabolism traits have been identified in several crops.Although barley is one of the important cereal crops,research on the genetic basis of phenolic acid synthesis in barley grains remains limited.Here,we analyze the 39 phenolic acid metabolites detected in mature grains of barley double haploid(DH)population and further identify 154 metabolite quantitative trait loci(mQTLs)related to 36 phenolic acids using four mapping methods.Subsequently,we identify 12 candidate genes that affect the content of phenolic acid metabolites,and overexpression of one candidate gene,HvCOMT-1,in barley reveals its involvement in the synthesis of phenolic acids.Moreover,we show that the transcription factor HvMYB-1 regulates the expression of HvCOMT-1.Functional analysis in Arabidopsis shows that HvCOMT-1 increases stem diameter and lignin deposition.Further analysis reveals that the expression level of HvCOMT-1 is closely related to the barley lodging-related traits.Overall,our findings enhance the understanding of the genetic basis for phenolic acid variations in mature barley grains and provide valuable reference for genetic improvement of barley nutritional quality. 展开更多

In order to investigate the effects of oxide particles on the high-temperature resistance and ablation performance of ceramicizable phenolic resin composites,three types of quartz fiber-reinforced ceramicizable phenolic resin composites were prepared using MgO particles or Al2O3 particles as the second-phase oxides and ZrB2 particles as the high-temperature ceramic filler,through a mold pressing process.The enhancement effects and mechanisms of the added second-phase oxides on the high-temperature resistance and ablation performance of the composites were discussed and analyzed through high-temperature testing,phase characterization,oxyacetylene testing,and microstructure characterization.The results show that ZrB2 particles oxidize to form ZrO2 and B2O3 in an oxygen-rich high-temperature environment.The added second-phase oxide particles can react with B2O3 to form corresponding borates,thereby strengthening the matrix.After treatment at 800℃,the flexural strength of the ZrB2-MgO quartz fiber-reinforced phenolic resin composite(QFPR/ZM)increased by 55.3%compared to the ZrB2 quartz fiber-reinforced phenolic resin composite(QFPR/Z).The oxyacetylene ablation performance of the composites with added oxide particles was significantly influenced by the generated borates.Mg3B2O6 has a higher high-temperature viscosity than Al18B4O33 at high temperatures,resulting in a lower linear ablation rate for QFPR/ZM compared to the ZrB2-Al2O3 quartz fiber-reinforced phenolic resin composite(QFPR/ZA). 展开更多

Central fatigue is closely linked to disruptions in the microbiota-gut-brain axis(MGBA),yet the molecular mechanisms involved remain largely unclear,and effective nutritional interventions are still limited.Tartary buckwheat polyphenols(TBP) have demonstrated potential in modulating the gut microbiota and supporting neuronal function.However,the specific pathways through which TBP exert their anti-fatigue effects are not fully understood.Clarifying these mechanisms is crucial for the development of precision dietary strategies to alleviate central fatigue.In this work,we established a mouse model of overexercise-induced central fatigue to systematically evaluate the effects of TBP through behavioral assessments,histological examination,neurotransmitter profiling,and inflammatory and oxidative stress marker analysis.The results showed that TBP significantly improved fatigue-related behaviors,alleviated intestinal and brain tissue damage,and modulated the expression of various neurotransmitters.Furthermore,TBP significantly reduced serum levels of pro-inflammatory cytokines(e.g.,interleukin-1 beta,and tumor necrosis factor-alpha),and mitigated oxidative stress by enhancing glutathione peroxidase and catalase activity and reducing malondialdehyde levels.16S rRNA sequencing revealed that TBP altered gut microbiota composition,promoting the abundance of beneficial taxa such as Lachnospiraceae,Lactobacillus,and Roseburia,while suppressing potentially harmful microbes.Short-chain fatty acids analysis further demonstrated that TBP modulated levels of acetic,propionic,and butyric acids,contributing to intestinal barrier integrity and energy homeostasis.Metabolomics analysis revealed that TBP influenced several key pathways,including alanine,aspartate,and glutamate metabolism,as well as neuroactive ligand-receptor interactions,thereby restoring the metabolic balance under central fatigue.Collectively,this work provides supportive evidence that TBP alleviates central fatigue through modulating the MGBA. 展开更多

Aiming at the selective adsorption removal and efficient separation of pollutant phenol from wastewater,a photo-responsive surface molecularly imprinted adsorbent with smart ultraviolet(UV)-switchable wettability has been designed and synthesized.The selective adsorption of phenol is achieved by constructing phenol-imprinted cavities with o-phenylenediamine(o-PD)as the functional monomer,while the reversible switching of surface wettability is realized through the synergistic effect of the photo-induced hydrophilic hollow titanium dioxide(H-TiO2)matrix and the cross-linked hydrophobic trimethylolpropane trimethacrylate imprinted polymer layer.The surface wettability of the constructed adsorbent o-PD/SMIP@H-TiO2can be changed from hydrophobic(water contact angle of 113°)to hydrophilic(water contact angle of 21°)after 30 min of UV irradiation,which is beneficial to the dispersion of the adsorbent and mass transfer of adsorbate.As the phenol adsorption takes place in the dark and reaches equilibrium(24.4 mg/g),the surface of o-PD/SMIP@H-TiO2gradually reverts to hydrophobicity,which facilitate the separation and regeneration of adsorbent,and the adsorption capacity in the 5th reuse maintains 94%.Furthermore,97%of the adsorbed phenol can be recovered from the saturated o-PD/SMIP@H-TiO2adsorbent.Meanwhile,the adsorbent demonstrates distinct specific recognition and selective adsorption performance towards phenol when multiple phenolic pollutants are present in the solution.The selectivity is attributed to the formation of hydrogen bonds between the nitrogen atoms on the directionally-arranged o-PD monomers within the imprinted cavities and the hydrogen atoms of phenol molecules.This photo-responsive imprinted adsorbent material is expected to exert a substantial influence on the wastewater purification industry. 展开更多

Poly(phenylene oxide)(PPO)exhibits excellent dielectric properties,making it an ideal substrate for high-frequency,high-speed copper-clad laminates.The phenolic hydroxyl group at the end of PPO plays a key role in its reactivity.Accurately quantifying the phenolic hydroxyl content in PPO is essential but challenging.In this study,we proposed a method for measuring the phenolic hydroxyl content of PPO using differential UV absorption spectroscopy.In alkaline solutions,the phenolic hydroxyl in PPO completely ionizes to form phenoxide ions,leading to a significant increase in UV absorbance at approximately 250 and 300 nm.Notably,the differential UV absorbance at approximately 300 nm was directly proportional to the phenolic hydroxyl concentration.Using 2,6-dimethylphenol as a standard,a calibration curve was established to relate the phenolic hydroxyl concentration to differential UV absorbance at approximately 300 nm,providing a precise and straightforward method for phenolic hydroxyl quantification in PPO with distinct advantages over conventional techniques. 展开更多

Polyoxometalate-based metal-organic complexes(POMOCs)which combine the structural features and performance advantages of MOCs and POMs,have a wide application in the field of catalysis.However,the catalytic capacity of POMOCs commonly cannot be fully utilized due to their imporosity and low surface area of single-crystals.In this work,a new POMOC with a formula of[Cu3O(4-atrz)6(PO3)(PMo12O40)](POMOC 1,4-atrz=4-amino-4H-1,2,4-triazole)was synthesized.And the size regulation of POMOC 1 from single-crystal to nanoscale was achieved by using citric acid as a modulator and adjusting the reaction temperature.Nano-sized POMOC 1 exhibited excellent catalytic performance in the oxidation reaction of phenols owing to the synergistic catalysis of POM and coordinatively unsaturated Cu(Ⅱ),and more surface-accessible catalytic sites of nano-catalyst. 展开更多

In environmental photocatalysis,it remains challenging to improve carrier separation efficiency and thereby enhance photocatalytic performance.In this study,N-doped graphene quantum dots(NGQDs)-NaBiO₃/BiOBr(NNB)p-n heterojunction photocatalysts were developed via simple ion-etching and in-situ deposition methods,exhibiting outstanding performance in the separation of electron/hole(e⁻/h⁺)pairs and showing significantly enhanced visible light degradation activity toward phenol.The DFT computations indicated that photogenerated electrons transferred from p-BiOBr to n-NaBiO₃,and NGQDs as electron acceptors and donors could promote the transfer of the photogenerated electrons and facilitate the separation of e⁻/h⁺ pairs.The enhanced photocatalytic performance of NNB was ascribed to the p-n heterojunction formed by NaBiO₃ and BiOBr and the strong electron transfer/storage ability of NGQDs.Based on capture tests and electron spin resonance measurements,superoxide radicals and photogenerated holes were identified as the primary active species,while linear oxygen was the secondary active species in the visible light degradation of phenol over NNB.In addition,the excellent photocatalytic activity,high photostability,and strong mineralization ability toward phenol demonstrated that NNB hybrid materials had promising application potential for pollutant degradation.This work offers a unique strategy for enhancing the photocatalytic efficiency of commercial NaBiO₃·2H₂O for environmental applications. 展开更多

Type 2 diabetes mellitus(T2DM)is a chronic metabolic disorder characterized by hyperglycemia,oxidative stress,and inflammation.Synthetic phenolic antioxidants(SPAs),primarily butylated hydroxyanisole,butylated hydroxytoluene,and tert-butylhydroquinone,have been widely detected in various environmental and consumer product matrices.Although they possess free radical scavenging ability,SPAs have dual effects on T2DM under different conditions.This review aims to outline the current research landscape in this field.We systematically analyze the literature and specifically note that the current understanding of the association between SPAs and T2DM is predominantly based on hypotheses from animal and cellular experiments,whereas direct human research data remain extremely scarce.This article elaborates on the paradoxical roles of SPAs,potentially increasing disease risk while alleviating complications,and analyzes the underlying regulatory mechanism centered on the balance of the nuclear factor erythroid 2-related factor 2uclear factor kappa-light-chain-enhancer of activated B cells pathway.Finally,we emphasize the urgent need for future welldesigned,large-scale human studies to fill this critical evidence gap and clarify the precise role of SPAs in T2DM. 展开更多

Lignin-derived oxygenated aromatics,particularly phenols and aromatic ethers obtained through depolymerization,represent promising feedstocks for synthesizing high-density and high-heat-sink aviation fuels via alkylation-hydrogenation processes.This study systematically evaluates the catalytic performance of various zeolites(Hβ,HZSM-5,MCM-41 and HUSY)in the alkylation reaction of phenol with cyclohexanol.Characterization results demonstrate that HUSY zeolite showed superior catalytic activity compared to other zeolites,attributable to its favorable pore architecture and well-balanced acid site distribution that synergistically facilitate molecular diffusion and catalytic transformations.To further enhance the catalytic properties,HUSY zeolite was modified with citric acid at various concentrations and compared with those treated with NaOH and oxalic acid.The results revealed that citric acid treatment preserved the crystallinity of the zeolite while modulating its acid distribution and pore structure.All modified zeolites enhanced phenol alkylation activity.Notably,the HUSY-0.5M catalyst,which exhibited the highest medium-strong acid to total acid ratio,achieved superior catalytic performance,80.4%conversion of phenol and 99.6%selectivity for alkylation products.The catalyst also exhibited high activity in the alkylation of various lignin-derived compounds,demonstrating its broad applicability.This work provides a new strategy for the valorization of lignin-derived phenols into high-value fuel precursors through alkylation. 展开更多

Metallic and phenolic compounds significantly impact the stability,flavor,and clarity of brandy,with implications for precipitation formation and human health.This study evaluated the effects of non-mineral pure-fiber paperboard(PF)and paperboard containing mineral filter(MF)on metallic elements and phenolic substances in ice wine pomace brandy aged in oak chips.The contents of 22 metallic elements were determined by inductively coupled plasma–mass spectrometry.Phenolic compounds were profiled by UHPLC–Q Exactive Orbitrap-MS and quantified by UPLC.Results demonstrated that temperature critically influenced metallic precipitation in MF,with Ca,Fe,Mg,Zn,and K increasing significantly at higher temperatures.Filtration markedly reduced polyphenol content,however,PF minimized phenolic loss compared to MF.A comparative analysis revealed that PF was superior to MF in reducing metallic introduction and preserving phenolic content.Thus,PF filtration at low temperatures(e.g.,0°C)effectively clarifies and stabilizes ice wine pomace brandy while preserving phenolic compounds. 展开更多

Modern society punishes us by aging earlier.Relying on advanced medicine and pharmacology for prevention and control raise concerns about long-term safety.Therefore,diet-driven nutritional anti-aging strategies are being strongly promoted.Phenolics are natural treasures from dietary sources and contain the potential for anti-aging and disease prevention.Based on this,the review fi rst describes the exploration and development of markers indicating aging.The potential and mechanisms of phenolics in managing aging are further synthesized.The morphology,preparation methods,and recent advances in nano strategies suitable for clinical oral delivery are reported to provide a feasible basis for resource integration of phenolics.Finally,its application is comprehensively considered,and constructive comments are made regarding challenges and future development.Even though relevant products have appeared on the market,achieving compliance and commercialization still faces multiple constraints and many challenges,which place greater demands on integrating new strategies and regulating the market. 展开更多

The most common secondary metabolites of plants,phenolics are found throughout the kingdom of plants.Plant polyphenols are receiving more and more attention because of their strong antioxidant qualities and their notable impact in preventing a number of disorders linked to oxidative stress,including cancer.This study examines phenolic acid extraction and determination techniques used in medicinal plants.The creation and identification of phenolic compounds or extracts from various plants has emerged as a key field of study in the health and medical sciences in recent years.An extensive and up-to-date summary of phenolic extraction,purification,analysis,and quantification as well as their anti-oxidant properties is given in this review.In addition,recent human intervention trials and the anticancer effects of phenolics in in vivo and in vitro animal models are examined.Supercritical fluid extraction(SFE)and accelerated solvent extraction(ASE)are two more methods that can be used to extract phenolic acids from plant materials,while Soxhlet extraction and ultrasonic aided extraction(UAE)are the most widely employed methods.Thanks to recent advancements in this technology,particularly when combined with mass spectrometry(MS),phenolic acids are typically measured via liquid chromatography(LC)following extraction. 展开更多
