Plant essential oils, with high bioactivity and biodegradability, provide promising alternatives to synthetic pesticides for pest control. Trans-anethole is the major component of essential oil from star anise, Illicium verum Hook. The compound has a strong contact toxicity against the green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), which is a major insect pest of many vegetables and crops. However, little information is known about how M. persicae responds to trans-anethole at the molecular level. We conducted a comparative transcriptome analysis of M. persicae in response to a LD50 dose of trans-anethole. A total of 559 differentially expressed genes were detected in the treated individuals, with 318 genes up-regulated, and 241 genes down-regulated. Gene ontology (GO) analysis revealed that these genes were classified into different biological processes and pathways. We also found that genes encoding ATP-binding cassette (ABC) transporters, DnaJ, and cuticle proteins were dramatically up-regulated in response to trans-anethole. To study the function of these genes, we performed RNA interference (RNAi) analysis. Knockdown of an ABC transporter gene (ABCG4) and a DnaJ gene (DnaJC1) resulted in a significantly increased mortality rate in M. persicae following trans-anethole exposure, indicating the involvement of these two genes in the toxicity response to trans-anethole. The findings provide new insights into the mechanisms of M. persicae in coping with plant essential oils.

Plant-derived terpenoids are essential secondary metabolites exhibiting broad-spectrum antibacterial properties. However, the bioactivities of terpenoids against Ralstonia solanacearum remain unexplored. Herein, the bioactivities of 30 terpenoids against R. solanacearum were assessed, and trans-anethole (TAN) was identified as a potent antibacterial agent with a minimum inhibitory concentration and minimum bactericidal concentration of 50 and 75 mg/L, respectively. TAN was low-toxic to silkworms, earthworms, seeds, and E. coli. Furthermore, TAN (>25 mg/L) significantly impeded the R. solanacearum growth, blocked ATP and exopolysaccharide (EPS) synthesis, caused DNA damage and cell rupture, and affected swimming motility and biofilm formation, and suppressed expressions of related genes. Compared with thiodiazole copper, and ethylicin, 100 mg/L TAN had a significantly greater control efficiency in both greenhouse and field tests. Importantly, TAN enhanced the abundance of the beneficial bacteria Bacillus and Sphingomonas. These findings highlight TAN as a potential bacterial wilt control agent.

Antimicrobial activity is an attractive property for packaging materials which can extend the shelf life of products and provide microbial safety for consumers. The study aimed to analyze the physicochemical and antimicrobial properties of gelatin-based edible films containing trans -anethole as the active additive. Encapsulation with β-cyclodextrin was used as an effective way to introduce trans -anethole into gelatin matrix. The results showed that the trans -anethole/β-cyclodextrin inclusion complex could be evenly dispersed in the gelatin-based edible films with appropriate addition. The incorporation of trans -anethole conferred the edible films with good antimicrobial activity as expected, which increased with the content of trans -anethole increasing. Moreover, the addition of inclusion complex improved the tensile strength and surface hydrophobicity and reduced the moisture content of the edible films. It was interesting that the edible films presented great UV light barrier property and it was increased by the addition of inclusion complex. Overall, the antimicrobial gelatin-based edible films showed great potential as bioactive packaging materials to extend food shelf life.

This article reports a novel type of biobased magnetic hollow particles (BMHPs) derived from a widely available biophenylpropene trans -anethole (ANE). To prepare BMHPs, ANE and maleic anhydride (MAH) underwent copolymerization in the presence of particulate templates to form core/shell particles. Sequential removing the cores and hydrolyzing processes provide biobased hydrolyzed hollow particles (BHHPs), which were then grafted with amino-modified Fe 3 O 4 NPs. The prepared BMHPs were characterized by SEM, TEM, XRD, VSM, EDS and FT-IR techniques and further used as bioadsorbent to remove pollutants from wastewater. The maximum adsorption capacity towards Cr 3+ , Pb 2+ and Rhodamine B is up to 44.5, 48.8 and 50.4 mg/g, respectively. Kinetic and isothermal studies show that the adsorption is best fitted with pseudo-second order model and Langmuir isothermal adsorption. BMHPs demonstrated remarkable magneticity and can be easily separated by external magnet. Recycling use study showed that the dye-adsorbed BMHPs can be easily restored in HCl/THF mixed solution. The advantages of the new adsorbents, namely, derivative from bio-resource, high adsorption capacity, much ease in separation and regeneration recyclability, render them with promising potentials in wastewater treatment.

Trans -anethole (AT) has a variety of antimicrobial properties and is widely used as food functional ingredient. However, the applications of AT are limited due to its low water solubility, strong odor and low physicochemical stability. Therefore, the aim of this work was to encapsulate AT with β-cyclodextrin (β-CD) for obtaining inclusion complex by co-precipitation method. The measurements effectively confirmed the formation of inclusion complex between AT and β-CD. The results showed that the inclusion complex presented new solid crystalline phases and was more thermally stable than the physical mixture and β-CD. The phase solubility study showed that the aqueous solubility of AT was increased by being included in β-CD. The calculated stability constant of inclusion complex was 1195 M − 1 , indicating the strong interaction between AT and β-CD. Furthermore, the release study suggested that β-CD provided the protection for AT against evaporation. The release behavior of AT from the inclusion complex was controlled.

The safe storage and protection of grain includes the exploitation of plant-based fumigants as a green control technology. This study first determined the fumigant toxicity of 12 traditional Chinese medicinal plants against adults of the rusty grain beetle, Cryptolestes ferrugineus (Stephens), one of the most ubiquitous and pestilent grain storage pests worldwide. Exposure to volatiles released from Illicium verum Hook. f. powder was found to be by far the most lethal. Illicium verum power and its volatiles eluent were then confirmed to be highly effective in killing both larvae and adults of C. ferrugineus . Star anise volatiles also showed good biological activity against Lasioderma serricorne (Fabricius) and Sitophilus zeamais Motschulsky, but not Tribolium castaneum Herbst. No significant differences were found in mortality of the adults of the rusty grain beetle when exposed at different temperatures ranging from 15−35°C. Gas chromatography-mass spectrometry (GC–MS) analysis showed that the main components of the eluent of star anise powder were trans -anethole (62.60%), estragole (23.70%), linalool (3.66%) and d -limonene (2.15%). In the fumigation test using synthetic standards of these four chemicals, only trans -anethole showed effective biological activity with exposure to 30 mL/L trans -anethole for 24 h resulting in 100% mortality of rusty grain beetle adults. Estragole did significantly enhance fumigant efficiency of trans -anethole. We further found that trans -anethole affects the beetles acetylcholinesterase activity, which was inhibited and decreased by 64.48% within 24 h. The results therefore show that trans -anethole, the major component of star anise volatiles contributes to its fumigant toxicity against C. ferrugineus by, at least partly, affecting its insect nervous system. Hence, star anise or its biologically active substances show very good potential to be used as a botanical insecticide to control C. ferrugineus .

Ulcerative colitis (UC) is the most common inflammatory bowel disease (IBD); it is incurable, and the treatment is expensive. Trans-anethole (TA), the main component of fennel, exhibits various biological activities. An increasing number of studies have demonstrated the efficacy of herbal active ingredients in the treatment of UC. This study aimed to investigate the effect and mechanism of TA in UC. In this study, we have experimented on mice with dextran sulfate sodium salt (DSS)-induced UC. The TA group was gavaged with 62.5 mg/kg TA by gavage once daily on days 8–14. To observe the effect of TA on the colon tissue, various investigations were performed, including western blot and immunohistochemistry for intestinal barrier protein expression, TUNEL staining for apoptosis, western blot, and ELISA for inflammation level, flow cytometry for Th17/Treg, LC–MS for blood bile acid content, GC–MS for blood fatty acid content, and 16s RNA for intestinal contents. TA alleviated weight loss in mice with UC; increased colon length; alleviated intestinal mucosal damage; upregulated claudin-1, occludin, and ZO-1 protein expression levels; reduced inflammatory factors in the colon and serum; and alleviated apoptosis. TA reduced fatty acid and bile acid levels by inhibiting colony abundance and reducing Th17/Treg cell differentiation in the colon. We found that TA alleviates DSS-induced UC by remodeling the intestinal flora to regulate immunity and bile acid metabolism.

Plant-derived trans- anethole (TAN) exhibits favorable antibacterial activity and biocompatibility, but poor solubility, photolysis, and volatility limit its use. Here, we prepared a TAN nanoemulsion (TAN-NE) via low-energy emulsification using non-ionic surfactants (polyethylene glycol tert -octylphenyl ether and polyoxyethylenated castor oil) and a co-surfactant (anhydrous ethanol). TAN-NE had spherical morphology, particle size of 20.68 nm, formulation yield (92.16%), encapsulation efficiency (88.49%), and loading efficiency (3.60%). It showed improved water solubility, photostability, and structural stability under various pH, ionic strength, temperature, and storage conditions. In vitro experiments demonstrated that TAN-NE enhanced the antibacterial efficacy of TAN against Ralstonia solanacearum by inhibiting protein and EPS synthesis, damaging cell integrity, reducing motility and biofilm formation, and the downregulating virulence genes. More importantly, TAN-NE displayed an efficient protective activity of 71.74% against tobacco bacterial wilt on 15-day post inoculation, surpassing those of TAN (52.17%) and thiodiazole copper (42.39%). Additionally, TAN-NE also exhibited good biosafety to earthworms, seeds, tobacco plants and soil environment. Collectively, our study provides a guidance for the nanoemulsion system of insoluble natural product.

Clean and safe water resources are essential for environmental safety and human health. Hydrogels and biomass polymers have attracted considerable attention in recent years, considering their nontoxicity, controllable performance, and high adsorption capacity. The interpenetrating network described here is a combination of a biomass polymer and a hydrogel adsorbent was established, the biomass polymer microspheres were first prepared with the combination of biomass monomer trans-anethole and maleic anhydride copolymer. A simple, environmentally friendly, and facile method of incorporating biomass polymer into sodium alginate biopolymer was developed by introducing the cross-linking agents calcium chloride and glutaraldehyde into the biomass polymer. Furthermore, the biomass polymer sodium alginate hydrogel (BP@SA/H) was characterized by FTIR, XPS, SEM, and XRD. In order to test materials' performance, the removal of pollutants and the adsorption study were also investigated after and before adsorption toward metals and dyes in water. We examined the factors influencing the materials, adsorption capability, such as initial concentration, time, absorbent amount, and pH. Moreover, the maximum adsorption values for Pb +2 and Cd +2 were 734.9 and 722 mg/g. While the adsorption toward RhB dye are 745 mg/g. In addition, the adsorption results were investigated using kinetic and isothermal models, demonstrating that biomass polymer hydrogel adsorption is chemisorption. Therefore, the as-developed biomass polymer sodium alginate hydrogel (BP@SA/H) is an exceptional multifunctional material that can be used to remove hazardous pollutants from wastewater.
