An antibacterial film based on Chinese yam starch (D-sorbitol as plasticizer) incorporated with eugenol (YDE) was prepared for pork preservation. The structure of films was characterized and the evaluation of two plasticizers (glycerol and D-sorbitol) on their mechanical and barrier properties was performed to determine the vehicle of eugenol. The release behavior and antimicrobial activity of YDE were investigated and the application of the films for pork preservation was evaluated. The mechanical and barrier properties of films were dependent on plasticizer. The release of eugenol from films was well-controlled by two release mechanisms of diffusion and erosion. YDE displayed good eugenol dose-dependent antibacterial activity which was higher against E. coli than against L. monocytogenes and S. aureus . The film with 3% eugenol can extend the shelf-life of pork beyond 50%, suggesting that the film may have great potential in active packaging for extending the shelf-life of foodstuffs.

Based on the prodrug principle, aspirin eugenol ester (AEE) was synthesized, which can reduce the side effects of aspirin and eugenol. As a good candidate for new antithrombotic and anti-inflammatory medicine, it is essential to evaluate its preventive effect on thrombosis. Preventive effect of AEE was investigated in κ-carrageenan-induced rat tail thrombosis model. AEE suspension liquids were prepared in 0.5% sodium carboxymethyl cellulose (CMC-Na). AEE was administrated at the dosage of 18, 36 and 72 mg/kg. Aspirin (20 mg/kg), eugenol (18 mg/kg) and 0.5% CMC-Na (30 mg/kg) were used as control drug. In order to compare the effects between AEE and its precursor, integration of aspirin and eugenol group (molar ratio 1:1) was also designed in the experiment. After drugs were administrated intragastrically for seven days, each rat was injected intraperitoneally with 20 mg/kg BW κ-carrageen dissolved in physiological saline to induce thrombosis. The length of tail-thrombosis was measured at 24 and 48 hours. The blank group just was given physiological saline for seven days without κ-carrageenan administrated. The results indicated that AEE significantly not only reduced the average length of thrombus, PT values and FIB concentration, but also reduced the red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT) and platelet (PLT). The effects of AEE on platelet aggregation and anticoagulant in vitro showed that AEE could inhibit adenosine diphosphate (ADP)-induced platelet aggregation as dose-dependence but no notable effect on blood clotting. From these results, it was concluded that AEE possessed positive effect on thrombosis prevention in vivo through the reduction of FIB, PLT, inhibition of platelet aggregation and the change of TT and PT values.

Eugenol, as a natural antibacterial agent, has been widely studied for its inhibitory effect on the common food-borne pathogen Staphylococcus aureus (S. aureus). However, the widespread application of eugenol is still limited by its instability and volatility. Herein, γ-polyglutamic acid coated eugenol cationic liposomes (pGA-ECLPs) were successfully constructed by self-assembly with an average particle size of 170.7 nm and an encapsulation efficiency of 36.2%. The formation of pGA shell significantly improved the stability of liposomes, and the encapsulation efficiency of eugenol only decreased by 20.7% after 30 days of storage at 4 °C. On the other hand, the pGA layer can be hydrolyzed by S. aureus, achieving effective control of release through response to bacterial stimuli. The application experiments further confirmed that pGA-ECLPs effectively prolonged the antibacterial effect of eugenol in fresh chicken without causing obvious sensory effects on the food. The above results of this study provide an important reference for extending the action time of natural antibacterial substances and developing new stimuli-responsive antibacterial systems.

Fusariumwilt, mainly caused byFusarium oxysporum, affects ginger yield and quality worldwide. To explore a safe and sustainable method of preventing and controllingFusariumwilt, the inhibitory effects of eugenol onF. oxysporum FOX-1were analysed in this study. The results showed that eugenol inhibited the reproductive and vegetative growth ofF. oxysporum FOX-1in vitro. Microscopic observations revealed that eugenol disrupted the hyphal morphology ofF. oxysporum. In addition, eugenol destroyed the cell membrane integrity of the pathogenic fungi, resulting in the leakage ofF. oxysporum FOX-1intercellular contents, including electrolytes, soluble proteins, nucleic acids, and malonydialdehyde. Results of an in vivo inoculation test showed that eugenol exerted a strong inhibitory effect onFusariumwilt in ginger seedlings. In summary, eugenol had an inhibitory effect on the growth ofF. oxysporum FOX-1and controlledFusariumwilt in ginger seedlings. These findings provide a foundation for future development of botanical antifungal agents to manageFusariumwilt.Keywords:Fusariumwilt;eugenol;essential oil;antifungal activity;Zingiber officinale

Methyl eugenol (ME) is a highly potent sexual attractant for Bactrocera dorsalis , which plays a crucial role in agricultural pest management. In this study, a composite fiber membrane was prepared by polystyrene (PS), polyethylene glycol diacrylate (PEGDA), and ME through electrostatic spinning respectively. The effective release period of ME was prolonged by triggering PEGDA with UV light. The mass ratio of PS to PEGDA affects the morphology of the fibers as well as the loading capacity (LC) and encapsulation efficiency (EE) for ME. Under optimal test conditions, the diameter of the fibers was 1.70 μm, and the ME loading capacity and encapsulation efficiency were (7.80 ± 0.07%) and (85.84 ± 7.94%). The combination of PS and PEGDA was confirmed by FTIR analysis, while its excellent thermal stability was verified through TGA testing. In the PS/PEGDA-ME-UV membrane, the cumulative release rate of ME reached 81.97% by week 8, which conformed to a first-order model. In the trapping experiments, a 53% rate of Bactrocera dorsalis capture was maintained even by week 8, demonstrating its potential for application in agricultural biocontrol.

Aspirin eugenol ester (AEE) is a new potential pharmaceutical compound possessing anti-inflammatory, anti-cardiovascular disease, and antioxidative stress activity. The pharmacological activities of AEE are partly dependent on its regulation of cell apoptosis. However, it is still unclear how AEE inhibits cell apoptosis on the basis of its antioxidative stress effect. This study aimed to reveal the vascular antioxidative mechanism of AEE in response to H2O2-induced oxidative stress in HUVECs and paraquat-induced oxidative stress in rats. In the different intervention groups of HUVECs and rats, the expression of ASK1, ERK1/2, SAPK/JNK, and p38 and the phosphorylation levels of ERK1/2, SAPK/JNK, and p38 were measured. The effects of ASK1 and ERK1/2 on the anti-apoptotic activity of AEE in the oxidative stress model were probed using the corresponding inhibitors ASK1 and ERK1/2. The results showed that in the HUVECs, 200 μM H2O2 treatment significantly increased the phosphorylation of SAPK/JNK and the level of ASK1 but decreased the phosphorylation of ERK1/2, while in the HUVECs pretreated with AEE, the H2O2-induced changes were significantly ameliorated. The findings were observed in vitro and in vivo. Moreover, inhibition of ASK1 and ERK1/2 showed that ASK1 plays a vital role in the protective effect of AEE on H2O2-induced apoptosis. All findings suggested that AEE protects the vascular endothelium from oxidative injury by mediating the ASK1 pathway.

Marine biofouling severely impedes the development of marine engineering, while existing coatings suffer from inadequate environmental compatibility and insufficient long-term efficacy. To address these limitations, this study reported the fabrication of eugenol-functionalized ZnO (ZnO@Eug) via a one-pot hydrothermal approach. Subsequently, ZnO@Eug was further modified with hexadecyl trimethyl ammonium bromide (CTAB) via electrostatic interactions to yield the ZnO@Eug@CTAB composite filler, which was then incorporated into a polydimethylsiloxane (PDMS) matrix to fabricate the ZnO@Eug@CTAB/PDMS (ZECP) composite coating. Benefiting from the synergistic effects of Zn 2+ , eugenol, and CTAB, the ZECP coating achieved 100 % antibacterial efficiency against E. coli after 24 h of co-cultivation with bacterial suspensions. Anti-algal and anti-marine organism experiments demonstrated that the ZECP coating effectively suppressed Chlorella colonization and prevented the attachment of conchs. Moreover, the ZECP coating displayed controlled Zn 2+ release behavior while maintaining a high water contact angle of 121° and low surface free energy of 20.2 mN·m −1 , thereby contributing to its long-term antifouling performance. Based on the dual functions of active antibacterial and anti-marine organism adhesion, the ZECP coating can be applied in the field of environmentally friendly marine antifouling coatings.

Essential oil-loaded emulsion is known to be unstable against Ostwald ripening. Hence, aiming to cut off this phenomenon, we fabricated eugenol-in-water emulsion by using co-stabilization method including interfacial layer formed by cinnamaldehyde/chitosan (CA-chitosan) and surfactant of glycerol monocaprylate (GMC). Oiling-off occurred in the emulsion with GMC as the sole stabilizer. While only white precipitates appeared in the CA-chitosan-stabilized emulsions due to the higher density of eugenol . In the presence of co-stabilizers, the particle size of emulsions showed unimodal distribution and kept almost constant within three months. Although there were some white precipitates in the emulsion after long-time storage, oil droplets still kept intact under optical microscopy. This result indicated that co-stabilizers could help to suppress the process of Ostwald ripening. The addition of polyvinyl alcohol effectively enhanced the stability of emulsions against gravitational separation. Eugenol emulsions kept stable even when eugenol content was up to 5 and 10 wt%. Antibacterial assay and time-kill experiment indicated that encapsulated eugenol had better antibacterial activity and long-term antibacterial efficiency, as compared to free eugenol. The obtained knowledge provides a novel technique to prepare eugenol-in-water emulsions, which has good long-term stability and antibacterial activity.

In this work, HZSM-5, Al-SBA-15 and Al-SBA-15/HZSM-5 were adopted as supporting materials for the nickel-based catalysts used in hydrodeoxygenation process. Incipient wetness impregnation method was employed to load nickel species onto these materials. The physicochemical characterization was carried out using advanced instruments. The effect of composition of nickel-based catalysts on hydrodeoxygenation (HDO) reaction was studied. Support materials of nickel-based catalyst have a significantly impact on HDO activity. The highest selectivity (67.9%) of propyl-cyclohexane was obtained over nickel based Al-SBA-15/HZSM-5 catalyst, and nearly all the eugenol was completely hydrodeoxygenated after reaction. The impact of light fractions existed in bio-oil on phenols upgrading process was investigated. The conversion of eugenol mixed with light fractions reached nearly 100% for all the reactions. Eugenol mixed with light fractions as reactant could reduce ring break reaction during hydrodeoxygenation process. The selectivity of alkanes remained nearly unchanged after adding ethylene glycol into the reactant. However, the selectivity of propyl-cyclohexane was significantly decreased by mixing furfural or acetic acid with eugenol as reactant.

Vitamin K 2 (VK 2 ) and vitamin D 3 (VD 3 ) can synergistically promote calcium absorption and reduce the prevalence of osteoporosis. Given their hydrophobicity and environmental sensitivity, stabilizing both these vitamins is pivotal for their application. In this study, we designed shellac-gliadin composites (SGCs) with favorable amphiphilicity, yielding a self-emulsifying delivery system (SEDS) upon mild mixing with eugenol. By increasing eugenol/SGCs mass ratio, SEDS was transformed from spherical to a network-like structure, forming tunable topological nanostructures with tailorable delivery performance and bioavailability. Based on the dual-step process, VK 2 was encapsulated during shellac-gliadin assembly, while VD 3 was co-encapsulated via self-emulsification. The generated dual-vitamin self-emulsifying system (DSEDS) improved the stability under UV-light and long-term storage for both vitamins with high encapsulation capacities of 48.05 and 9.36 mg/g for VK 2 and VD 3 , respectively. The dual-step strategy introduced a novel approach for loading various fat-soluble nutrients, with potential applications in food and nutrition industry.

SUMMARY Cold and drought stress are the most critical stresses encountered by crops and occur simultaneously under field conditions. However, it is unclear whether volatiles contribute to both cold and drought tolerance, and if so, by what mechanisms they act. Here, we show that airborne eugenol can be taken up by the tea ( Camellia sinensis ) plant and metabolized into glycosides, thus enhancing cold and drought tolerance of tea plants. A uridine diphosphate (UDP)-glucosyltransferase, UGT71A59, was discovered, whose expression is strongly induced by multiple abiotic stresses. UGT71A59 specifically catalyzes glucosylation of eugenol glucoside in vitro and in vivo . Suppression of UGT71A59 expression in tea reduced the accumulation of eugenol glucoside, lowered reactive oxygen species (ROS) scavenging capacity, and ultimately impaired cold and drought stress tolerance. Exposure to airborne eugenol triggered a marked increase in UGT71A59 expression, eugenol glucoside accumulation, and cold tolerance by modulating ROS accumulation and CBF1 expression. It also promoted drought tolerance by altering abscisic acid homeostasis and stomatal closure. CBF1 and CBF3 play positive roles in eugenol-induced cold tolerance and CBF2 may be a negative regulator of eugenol-induced cold tolerance in tea plants. These results provide evidence that eugenol functions as a signal in cold and drought tolerance regulation and shed new light on the biological functions of volatiles in the response to multiple abiotic stresses in plants.

Fusarium graminearum poses a major threat to global grain production due to its pathogenicity and mycotoxin contamination. This study explored the antifungal effects and characterized molecular alterations of eugenol, a plant-derived phenolic compound, against F. graminearum . An integrated multi-omics strategy combining transcriptomic and lipidomic analyses was employed to characterize stage-specific responses of conidia and mycelia to eugenol, complemented by phenotypic and biochemical assays. Eugenol exhibited pronounced dose-dependent antifungal activity, accompanied by compromised cellular integrity and disruption of lipid homeostasis. Notably, its mode of action displayed clear developmental specificity. In the conidial stage, eugenol may interfere with phosphatidylcholine transport and membrane lipid remodeling, potentially limiting the membrane supply required for polarized growth. In contrast, during the mycelial stage, eugenol exposure correlated with the induction of peroxisome-associated lipid catabolism and stress responses, likely resulting in metabolic imbalance and growth suppression. Collectively, these findings delineate a stage-specific landscape of F. graminearum responses to eugenol and propose a hypothetical model centered on lipid metabolic disruption, supporting the further development of eugenol-based antifungal strategies for controlling F. graminearum .
