China has a large variety of edible mushrooms and ranks first in the world in terms of production and variety. Nevertheless, due to their high moisture content and rapid respiration rate, they experience constant quality deterioration, browning of color, loss of moisture, changes in texture, increases in microbial populations, and loss of nutrition and flavor during postharvest storage. Therefore, this paper reviews the effects of essential oils and plant extracts on the preservation of edible mushrooms and summarizes their mechanisms of action to better understand their effects during the storage of mushrooms. The quality degradation process of edible mushrooms is complex and influenced by internal and external factors. Essential oils and plant extracts are considered environmentally friendly preservation methods for better postharvest quality. This review aims to provide a reference for the development of new green and safe preservation and provides research directions for the postharvest processing and product development of edible mushrooms.Keywords:edible mushrooms;essential oils;plant extracts;postharvest;mechanism

In this paper, corrosion inhibition performance of Helianthus tuberosus L extracts(HTLE) and Poria cocos extracts(PCSE) alone and compounded with Na 2 SiO 3 in 0.01 mol L −1 NaOH solution on AA2024-T3 aluminum alloy was investigated by weight loss, electrochemical impedance spectroscopy, potential polarization, atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS), quantum chemical calculations and molecular dynamics simulations. Infrared spectroscopy was used to study the main active components in both extracts. The results revealed that when the two extracts were utilized separately, the corrosion inhibition impact was insignificant. However, when compounded with Na 2 SiO 3 , the corrosion inhibition efficiency was greatly enhanced. Fixing the concentration of Na 2 SiO 3 at 610 mg L −1 , the inhibition effectiveness rose with the increase of the concentration of the extracts, and when the concentration of HTLE, PCSE were 800 mg L −1 and 1000 mg L −1 , respectively, the inhibition efficiencies could reached approximated 98 %. The two compounds were anodic-dominant hybrid corrosion inhibitors. AFM and XPS analysis revealed that the two compounds could successfully adsorb on the aluminum alloy surface, protecting the metal from corrosion. Theoretical simulations were conducted by selecting the three major components from each of the two extracts. Quantitative chemistry calculations indicated the accepted and donated electron groups of the major components. Molecular dynamics simulations show that the primary components compounded with Na 2 SiO 3 have a higher negative adsorption energy than their action alone.

Many methods for management of mirid bugs, one of the major pest species in cotton fields, have been developed in recent decades. The use of attractive plant volatiles may be a safe and effective alternative compared with chemical pesticides. Very little is known about the responses of the bugs to some specific volatiles. In this study, the attractive effects for the mirid bug Apolygus lucorum were evaluated and compared among ethanol extracts obtained from six types of plants. The results showed that A. lucorum had the highest selection response rate to the extract from Allium tuberosum seeds and 70.51% of the adults tended to choose this odour source. Among 40 identified compounds of the volatiles comprising A. tuberosum seed extracts, diethyl phthalate and methyl levulinate had significantly higher attractive effects than that of cotton leaves, but the respective selection response rates were less than 65%. We found that when methyl levulinate and diethyl phthalate were mixed in volume ratios of 3:7 and 6:4, the selection response rates of A. lucorum for the mixtures were 54.67% and 63.65%, respectively. These response rates were significantly higher than those for the two compounds presented alone. Furthermore, the selection response rates of A. lucorum based on these mixtures reached 82.75% and 75.73%, respectively when compared with cotton leaves. The two volatile mixtures also showed a significantly higher attractive effect for Adelphocoris suturalis , with respective selection response rates at 74.58% and 77.80% when compared with cotton leaves. Moreover, the two attractants showed no difference between the responses of male and female mirid bugs. We concluded that an appropriate application of the attractants described herein has the potential to develop a safe and effective approach for the monitoring and control of mirid bugs in cotton fields.

With the assistance of plant extracts, the facile synthesis of three-dimensional (3D) porous LaCoO3 perovskite is reported at a lower calcination temperature of 500 °C. The formation mechanism is carefully studied by investigating the different roles of organic and inorganic components in Cacumenplatycladi extract. The results indicate that organic components (mainly phenolic acids) function as the similar complex species of citric acid, while the mineral nutrients (Na+, K+, Ca2+, and Mg2+) together with NO3– serve as combustion-aid agents even with trace amounts. Moreover, the biosynthesized LaCoO3 has a high surface area of 32.5 m2 g–1 and exhibits excellent catalytic performance for benzene oxidation. Benzene of 1000 ppm can achieve a stable conversion above 90% at 285 °C in a continuous run for 80 h (weight-hourly space velocity (WHSV) = 40 000 mL g–1 h–1). It can be attributed to the bio-LaCoO3 with more electrophilic adsorption of oxygen species and 3D porous structure.

Extracting rare earth elements (REEs) from wastewater is crucial for saving the environment, sustainable use of natural resources and economic growth. Reported here is a simple, low cost and one-step synthesis of Fe nanoparticles (FeNPs) based on two plant extracts having the ability to recover REEs. The synthesis of FeNPs using Excoecaria cochinchinensis leaves extract (Ec-FeNPs) exhibited high selectivity for heavy rare earth due to unique biomolecules, achieving separation coefficients (K d ) of 3.16 × 10 3 –4.04 × 10 6 mL/g and recovery efficiencies ranging from 71.7 to 100 %. Conversely, the synthesis of FeNPs using Pinus massoniana lamb extract (PML-FeNPs) revealed poorer REE recovery efficiencies of 7.2–86.7 %. To understand the differences between Ec-FeNPs and PML-FeNPs in terms of selectivity and efficiency, LC-QTOF-MS served to analyze the biomolecules differences of two plant extracts. In addition, various types of characterization were carried out to identify the different functional groups encapsulated on the surface of FeNPs. These results reveal the source of the difference in the selectivity of Ec-FeNPs and PML-FeNPs for REEs. Furthermore, during DFT calculations, it was found that biomolecules with varying affinities for the surface of FeNPs interact with each other, leading to the formation of structures that exhibit high reactivity towards REEs. Finally, incorporating Spearman correlation analysis demonstrates that the selective removal efficiency of REEs was closely linked to surface complexation, ion exchange, and electrostatic adsorption. Consequently, this work strongly highlights the potential for the practical application of novel adsorbents in this field.

Rice sheath blight is a destructive fungal disease caused by Rhizoctonia solani . To find a safe and green measure, the biological activity of six plant extracts against R. solani was determined by mycelial growth rate method. The results showed that magnolol possessed better antifungal activities against R. solani , with an EC 50 value of 7.47 mg/L. further action mechanism of magnolol against R. solani was carried out. Studies by scanning electron microscopy (SEM) showed that the morphology of R. solani mycelia was deformation and surface folds. Transmission electron microscope (TEM) observation on treated R. solani showed that magnolol could induce cytoplasmic membrane rupture and cytoplasmic membrane even disappeared completely accompanied with cellular debris was covered around this fungal, and the mycelia treated with magnolol showed fluorescence after PI staining. Further study showed that the content of malondialdehyde (MDA) and activity of chitinase , β-1,3-glucanase and relative conductivity of mycelia were increased, while the content of soluble protein and activities of catalase (CAT), polyphenol oxidase (PPO), superoxide dismutase (SOD), succinate dehydrogenase (SDH) and NAD-malate dehydrogenase (NAD-MDH) were significantly decreased. These results indicated that magnolol could significantly damage the plasma membrane of R. solani , and interfere with cell respiratory metabolism, thus inhibiting the growth of mycelium.

Recently, it has been shown that silver nanoparticles (AgNPs) exhibit great potential for different applications, including food storage, cosmetic products, electronic components, biosensor materials, cryogenics, dental materials and especially for drug-delivery activities. In this study, we synthesized AgNPs with neem extract (NE) alone and mixed plant extracts of neem, onion and tomato (NOT) as a combined reducing and stabilizing agent by a green synthesis method at different pHs. The synthesized products were characterized by ultraviolet-visible spectroscopy (UV-vis), X-ray diffraction (XRD), dynamic light scattering (DLS), atomic force microscopy (AFM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The antibacterial effects of the synthesized products were studied by the Kirby disk diffusion method. It was confirmed that the AgNPs work effectively as a drug material against Gram-positive bacteria Staphylococcus aureus in nutrient agar. In addition, it was seen that the reducing and stabilizing agent NOT could work effectively with six medicines with a different nature at the maximum addition of 15 μg. However, the synthesized product with NE alone only worked for four of the medicines. Therefore, it was evident that the AgNPs synthesized with NOT extract were more susceptible to the Gram-positive bacteria Staphylococcus aureus. We believe that this new route for synthesizing AgNPs with NOT extract could be more beneficial in comparison to NE alone for improved antibacterial properties in drug-delivery applications.

This study describes an inexpensive, simple and green method to form silver nanoparticles from different leaf extracts ofAchyranthes asperaandScoparia dulcisplants. The silver nitrate is reduced byAchyranthes asperaandScoparia dulcisleaf extracts respectively to generate two silver nanoparticle types symbolized as AA.AgNPs and SD.AgNPs. The optical absorption, size and morphology of silver nanoparticles are significantly impacted by extract types. The ultraviolet visible spectrum of AA.AgNPs shows a 433-nm peak being more broadened than that of SD.AgNPs. The Fourier infrared transform spectra of two of these silver nanoparticles revealed that their surface is modified by organic constituents from extracts, and thus they are stabilized in solution without any additional reaction. Images from transmission electron microscopy and scanning electron microscope indicate that AA.AgNPs are in clusters with the size of 8–52 nm almost possessing oval shape, while SD.AgNPs are smaller size of 5-45 nm separated well in diversified shapes (spherical, triangle, quadrilateral and hexagonal). Moreover, both AA.AgNPs and SD.AgNPs exhibit the highly antifungal effect againstAspergillus niger, Aspergillus flavusand the most strong impact onFusarium oxysporum.For these obtained results, two new silver nanoparticles are promising fungicides for various applications of medical and agricultural fields.Keywords:silver nanoparticle;fungicide;plant extract;Achyranthes aspera;Scoparia dulcis

Silver nanoparticles (AgNPs) are broad-spectrum antibacterial agents that are safe for the environment and the human body. To achieve a balance between material functionality, degradability, and safety of AgNPs, the peanut red skin (PSE)/polyphenol-hydroxypropyl-β-cyclodextrin (HPβCD)/AgNPs were prepared for the first time by ultrasound-triggered molecular encapsulation and biosynthesis for hydrophilic fusion of medicine and small molecules. Additionally, a novel “controlled release” sodium alginate (SA)-based hydrogel was developed and medicine/small-molecule self-assembled PSE/HPβCD/AgNPs were introduced into the three-dimensional network structure of the SA hydrogels. The SA-based hydrogels exhibited excellent mechanical and rheological properties. In different pH conditions, the hydrogels exhibit differing release and expansion behaviors, and the maximum cumulative release of AgNPs was 98.21% at pH > 6.8. Furthermore, the hydrogels exhibited strong antibacterial effects against pathogenic bacteria. They also showed excellent antioxidant properties and cytocompatibility. These advantages highlight the potential utility of the developed hydrogels for biomedical applications and agricultural fields.

Recently, the discharge of effluent containing dyes and other chemicals into river, lakes, and land has become a serious problem which increases the pollution level drastically. The dyes in the effluent are very difficult to be removed by conventional water treatment methods. Thus, there is a great need for more advanced methods that are cost-effective and more efficient. In this study, silver nano particles (AgNps) were synthesized by green method using extracts of onion (O), tomato (T), acacia catechu (C) alone, and mixed COT extracts. The reduction and formation of AgNps and its ions have been characterized by using several techniques, Ultra visible spectroscopy (UV–vis), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM)-energy dispersive X-ray spectrometer (EDX), Fourier transmission infrared spectroscopy (FTIR), and dynamic light scattering (DLS). These techniques revealed that the particle sizes of synthesized AgNps in all the extracts were ranged in between 5 and 100 nm with a crystalline nature. The synthesized AgNps were used as catalysts for the degradation of three different types of dyes, methyl orange (MO), methyl red (MR), and congo red (CR) in the liquid state. The excellent catalytic application of all the synthesized AgNps on the degradation of the studied dyes was confirmed via UV–visible results by studying the reduction in the absorbance maxima value within a very short interval of time. COT synthesized products were found to achieve the best performance for all dyes degradation among all products.

Panax notoginseng is a rare medicinal and edible plant widely used for multi-treatments, and in this study, a polysaccharide Pnp was prepared from P. notoginseng , and its structure and biology activities were investigated. Results showed that the molecular weight of Pnp was 78.6 kDa, and Pnp mainly consisted of →2,4)-α-L-Rha p -(1→, →5)-α-L-Ara f -(1→ and →4)-α-D-Gal p -(1→ residues with acetyl groups. Furthermore, the macrophages were activated the immunologic function after TLR2 and MR recognizing Pnp. Besides, Pnp could be durative utilized by the probiotic Lactobacillus plantarum and the account of viable cells kept at 9.5 log CFU/mL for 72h. The hydrophobicity and the short-chain fatty acids levels (especially butyric acid) of L. plantarum were enhanced by Pnp, which indicated that Pnp exerted beneficial effects on the host health. The results laid a solid foundation for the exploitation of Pnp as a nutraceutical and functional candidate in the food industry.

This article reports on silver nanoparticles (AgNPs) that were green-synthesized by usingEriobotrya japonica(Thunb.) leaf extract and their use for the catalytic degradation of reactive dyes. The properties of biogenic AgNPs were characterized using UV-vis absorption spectroscopy, field emission scanning electron microscope (FESEM), X-ray powder diffraction (XRD), transmission electron microscope (TEM), Fourier transforming infrared spectroscopy (FTIR), energy dispersive X-ray spectroscopy (EDS), and selected area electron diffraction (SAED) analysis. The UV-vis spectroscopy and X-ray analyses confirmed the formation of AgNPs and showed the strong absorbance around 467 nm with surface plasmon resonance (SPR). The mean diameter of biogenic AgNPs at room (20 °C), moderate (50 °C), and high temperatures (80 °C) were 9.26 ± 2.72, 13.09 ± 3.66, and 17.28 ± 5.78 nm, respectively. The reaction temperature had significant impacts on the sizes of synthesized AgNPs. The higher the synthesis temperature, the larger size and the lower catalysis activity for reductive decomposition of reactive dyes via NaBH4. The results supported a bio-green approach for developing AgNPs with a small size and stable degradation activity of reactive dyes over 92% in 30 min by usingEriobotrya japonica(Thunb.) leaf extract at pH 7, 20 °C, and 1:10 ratio of silver nitrate added to the leaf extract.Keywords:green biosynthesis;silver nanoparticles;Eriobotrya japonica;plant extract;catalyst
