Xanthoceras sorbifoliaBunge. is used in traditional medicine in North China. To evaluate the anti-tumor and radical-scavenging activities ofX. sorbifoliahusks polyphenols and determine their structure-activity relationships, 37 polyphenols1–37were obtained by bioassay-guided fractionation. Two new compounds1–2, and compounds5,6,8,9,11,14–17,21–25,27–29,31,33,34,36, and37were isolated from the genusXanthocerasfor the first time. Compounds1–37did not show strong cytotoxicity against the four tested tumor cell lines (A549, HepG2, MGC-803, and MFC) compared to paclitaxel and under the conditions tested in the anti-tumor assay, but compounds3,4,7,8,10,18–20,25,26,29,30,32, and35exhibited stronger radical-scavenging activity than ascorbic acid in a 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt assay. This was the first report on the anti-tumor and radical-scavenging activities of the polyphenols isolated fromX. sorbifoliahusks. Overall, the present study contributed valuable information concerningX. sorbifoliahusks use in medicine and pharmacology.Keywords:Xanthoceras sorbifolia;polyphenols;extracts;anti-tumor activity;radical-scavenging activity

The physicochemical properties and fatty acid profile of natural Sapium sebiferum oil (SSO) were analyzed and found to have a high iodine value of 186.8 g/100 g. Then, a novel SSO-based polyurethane (PU) was successfully synthesized via an in situ polymerization method, and multi-walled carbon nanotubes (CNTs) were modified by an acid mixture and ethylenediamine (EDA) to further reinforce the PU matrix. The microstructure and the properties of the functionalized CNTs and the PU/CNT composites were characterized by Fourier transform infrared (FTIR), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). The results showed that amino-functionalized CNTs could homogeneously disperse in the PU matrix and significantly improved the thermal and mechanical properties of the composite. Compared with pure PU, the glass transition temperature and initial decomposition temperature of the PU matrix with amino-functionalized CNTs were respectively enhanced by 17.1 and 32.5 °C. Meanwhile, 295% improvement in the tensile strength, 111.3% enhancement in the Young's modulus and 22.4% increment in the elongation at break of the composite were observed. The properties of the PU/CNT composites indicate the great potential applications of SSO in polymer materials.

Seven fatty acids were detected by GC-MS inXanthoceras sorbifoliumBunge seed oil extracted at different temperatures, including Palmitic acid C16:0, Stearic acid C18:0, Oleic acid C18:1, Eicosenoic acid C20:1, Docosenoic acid C22:1, Tetracosenoic acid C24:1, and Linoleic acid C18:2. The highest content of nervonic acid (NA) was found inXanthoceras sorbifoliumBunge seed oil extracted at 70 °C. Three methods were selected to analyze the extraction rate of nervonic acid inXanthoceras sorbifoliumBunge seed oil, including urea complexation, low-temperature solvent crystallization, and a combined treatment using these two methods. The final content of nervonic acid obtained was 14.07%, 19.66%, and 40.17%, respectively. The combined treatment method increased the purity of nervonic acid inXanthoceras sorbifoliumBunge seed oil by 12.62 times. Meanwhile, thermogravimetric behavior analysis of samples extracted using different methods was conducted by thermogravimetric analyzer, which suggested that the thermal stability of the samples extracted by the combined treatment was enhanced. These results can provide a new process parameter and scientific basis for the extraction of NA. At the same time, FTIR and NMR were also used to characterize the combined extraction sample, and the structure of the samples was proved.

In recent years, the frequent occurrence of algal blooms has posed continuous threats to aquatic ecosystems and social safety. Environmentally friendly algae-inhibiting methods utilizing allelopathic substances offer advantages such as convenient application and low costs, presenting a bright application prospect in the fields of water and ecological restoration. This study aimed to investigate the procedure for extracting total flavonoids from Zanthoxylum bungeanum leaves and assess allelopathic mechanism of Z. bungeanum leaf extracts on Microcystis aeruginosa . The optimal extraction conditions were determined as follows: solvent-to-material ratio = 10 mL/g; extraction time = 55 min; ethanol volume fraction = 80%; and ultrasonic temperature = 80 °C. Antioxidant activity tests revealed that Z. bungeanum leaf extracts exhibit superior capacity compared to Butylated hydroxytoluene (BHT) but inferior to Vitamin C (VC). Moreover, high-concentration Z. bungeanum leaf extracts can disrupt the structures of oxygen-evolving complexes at the donor sides of photosystem II (PSII) reaction center and influence energy distribution at PSII reaction centers, thereby inhibiting electron transmission activities at both donor and receptor sides of the PSII reaction center. The elucidated allelopathic mechanism of Z. bungeanum leaf extracts provides theoretical evidence for the algal-bloom control and the development of allelopathic algae-inhibiting agents, offering a reference for the further comprehensive development and utilization of Z. bungeanum . Graphical High-concentration Z. bungeanum leaf extracts can disrupt the structures of oxygen-evolving complexes at the donor sides of photosystem II (PSII) reaction center and influence energy distribution at PSII reaction centers, thereby inhibiting electron transmission activities at both donor and receptor sides of the PSII reaction center.

In the present work, the extraction process of total flavonoids (TFs) fromX. sorbifoliaflowers by ultrasound-assisted extraction was optimized under the response surface methodology (RSM) on the basis of single-factor experiments. The optimal extraction conditions were as follows: ethanol concentration of 80%, solid–liquid ratio of 1:37 (g/mL), temperature of 84 °C, and extraction time of 1 h. Under the optimized conditions, the extraction yield of the TFs was 3.956 ± 0.04%. The radical scavenging capacities of TFs against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) were much greater than that of rutin. The results of antibacterial experiments indicated that the TFs displayed strong inhibitory activities onE. coli,S. aureusandBacillus subtilis. Therefore,X. sorbifoliaflowers can be used as a novel source of natural flavonoids, and the TFs have potential applications as natural antioxidants or antibacterial agents in the food and pharmaceutical industries.Keywords:Xanthoceras sorbifoliaBunge;total flavonoids;ultrasound-assisted extraction;response surface methodology;antioxidant activity;antibacterial activity

BackgroundXanthoceras sorbifolium Bunge leaves (XLs) are valuable resources rich in phytochemicals, especially in flavonoids, but they are rarely exploited and utilized.ObjectiveThe purpose of this paper is to reduce the waste of XLs resources (usually used as agricultural waste) and extract the high added value of active ingredients from XLs.MethodsThe extraction of flavonoids from XLs using ultrasonic-assisted extraction (UAE) was reported. Response surface methodology (RSM) was used to adopt different ultrasonic conditions such as ethanol concentration, liquid:solid ratio, and ultrasonic power. In addition, the chemical structures were identified using ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) and HPLC.ResultsResponse surface analysis indicated the optimal level of ethanol concentration, liquid:solid ratio, and ultrasonic power as 71.49%, 13.87 mL/g, and 157.49 W respectively for the maximum response of total flavonoids (5.52 ± 0.23%), which fitted well with the predicted value (5.68 ± 0.17%). In addition, the extracts from XLs exhibited potent antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) ammonium salt (ABTS).ConclusionThe potent antioxidant activity of flavonoids from XLs is beneficial for their application in the food and drug industry, which will facilitate the rise of the added value of the flavonoids from XLs.HighlightsMyricetin, rutin, and epicatechin, which may be responsible for the antioxidant activity of the extracts from XLs, were confirmed by UPLC–MS/MS and HPLC analysis. The extracted flavonoids can be used as a natural antioxidant additive to food products.

This study investigates the use of flavonoid-rich extracts from Zanthoxylum bungeanum pericarps (ZBPFs) for sustainable dyeing and functionalization of cationized cotton fabrics. The extracts were obtained through ethanol/water extraction and purified using macroporous resin, with flavonoids such as rutin, astragalin, coumarin, baicalin, and quercetin making up over 72 % of the total composition. Stability tests revealed that ZBPFs were stable under neutral or mildly acidic conditions but were highly sensitive to reducing agents, prolonged light exposure, and metal ions. Cotton fabrics modified with 3-chloro-2-hydroxypropyl trimethylammonium chloride and dyed with ZBPFs reached a maximum color depth (K/S value) of 12.5 at 5 % owf. Fabrics dyed with 2 % owf ZBPFs demonstrated excellent UV protection (UPF of 115.54), antioxidant activity (98.1 % radical scavenging), and antibacterial efficacy (over 98 % against E . coli and S . aureus ). The adsorption of ZBPFs onto cationized cotton fitted both the pseudo-second-order and Sips models. This indicates that chemical adsorption is the predominant mechanism and suggests multiple interactions between the ZBPFs and the fabric. The dyed fabrics exhibited high stability in rubbing and washing fastness, although their light fastness was comparatively lower. Further, washing with potassium aluminum sulfate significantly diminished the antioxidant and antibacterial properties, while washing with other solutions, such as tap water and deionized water, showed minimal effects on performance. This research highlights the potential of ZBPFs as a stable, bioactive, and environmentally friendly dye, offering considerable functional and ecological benefits in textile applications.

A novel and cyclic in situ transesterification of yellow horn ( Xanthoceras sorbifolia Bunge.) seeds to biodiesel using the switchable solvent, N , N -dimethylcyclohexylamine (DMCHA) as both a reusable solvent and catalyst was proposed. An optimizing study for the reaction conditions has been performed through response surface methodology. The maximum yield of fatty acid methyl esters (FAMEs) achieved 96.07% under the best conditions of temperature 63.93 °C, 28.05 min, methanol amount of 10.41 mL/g (v/w of material) and DMCHA amount of 16.42 mL/g. Notably, The results of mechanism study combined with molecular dynamics and quantum chemistry theory showed that DMCHA is compatible with the triglycerides, and the effect of the hydrogen bonds, interaction energy, and radial distribution function on DMCHA performance were investigated for the first time. This new configuration of using switchable solvent for simultaneous extraction and reaction would be an appropriate, efficient and environment-friendly approach for simplify biodiesel production.

Sapium sebiferum , an ornamental and bio-energetic plant, is propagated by seed. Its seed coat contains germination inhibitors and takes a long time to stratify for germination. In this study, we discovered that the S. sebiferum seed coat (especially the tegmen) and endospermic cap (ESC) contained high levels of proanthocyanidins (PAs). Seed coat and ESC removal induced seed germination, whereas exogenous application with seed coat extract (SCE) or PAs significantly inhibited this process, suggesting that PAs in the seed coat played a major role in regulating seed germination in S. sebiferum . We further investigated how SCE affected the expression of the seed-germination-related genes. The results showed that treatment with SCE upregulated the transcription level of the dormancy-related gene, gibberellins (GAs) suppressing genes, abscisic acid (ABA) biosynthesis and signalling genes. SCE decreased the transcript levels of ABA catabolic genes, GAs biosynthesis genes, reactive oxygen species genes and nitrates-signalling genes. Exogenous application of nordihydroguaiaretic acid, gibberellic acid, hydrogen peroxide and potassium nitrate recovered seed germination in seed-coat-extract supplemented medium. In this study, we highlighted the role of PAs, and their interactions with the other germination regulators, in the regulation of seed dormancy in S. sebiferum .

Zanthoxylum bungeanumleaves were regarded as a waste byproduct for a long period of time, yet their functional components presented potential as novel antimicrobial agents. However, their effectiveness in controlling algal blooms remains unexplored. In this study, the inhibition effect ofZ. bungeanumleaf extracts on algal blooms was firstly demonstrated, and the flavonoid profiles of the leaf extract were identified using non-targeted metabolomics analysis. Then, response surface methodology was performed for extraction to further evaluate the feasibility of industrial application. Specifically, the effects of extracts on the cell density, photosynthetic efficiency, and antioxidant activity ofTetrodesmus obliquuswas investigated. The results showed that the extraction yield of flavonoids fromZ. bungeanumleaves reached 6.85% under the optimized conditions of an ultrasonic power of 600 W, an LSR of 20:1 mL/g, an ethanol concentration of 77.5%, an ultrasonic duration of 18 min, and an ultrasonic temperature of 80 °C, which significantly decreased the Fv/Fm and PIabs values by 54.60% and 98.22%, respectively, after exposure ofT. obliquusto 40.0 mg/LZ. bungeanumleaf extract for 66 h. Meanwhile, treatment withZ. bungeanumleaf extract at a dose of 40.0 mg/L generated T-AOC values that were 4.0 times higher than the control without the addition ofZ. bungeanumleaf extracts. These results suggest thatZ. bungeanumleaf extracts could be used in the development of potentially effective biological algicides. Our study provides data to support the development of algicides and realizes the resource application ofZ. bungeanumleaf waste, achieving a synergistic outcome of both economic and ecological benefits.

The influence of ultrasonic treatment (100–500 W, 30 min) on the molecular structures and emulsifying properties of Zanthoxylum seed protein (ZSP) was explored for the first time in this work. Research results indicated that the all ultrasonic treatments at different power levels decreased the particle size but increased the surface charge of ZSP. In addition, the ultrasonic treatments induced the structural unfolding of the ZAP, as indicated by the increase in α-helix, ultraviolet–visible absorbance, surface hydrophobicity and the amount of surface free sulfhydryl groups, as well as the decrease in β-sheet and intrinsic fluorescence intensity. As a result, the significantly (p < 0.05) increased emulsifying activity index (EAI) and emulsion stability index (ESI) of ZSP were observed after ultrasonic treatment. In addition, the emulsion prepared by ultrasonically treated ZSP exhibited the smaller and more uniform droplets with significantly improved stability against environmental stress (temperature, salt concentration, pH), creaming and oxidation due to the increased ratio of interfacially adsorbed ZSP. Furthermore, ultrasonic treatment at 400 W was found to be the optimum condition for modification. These findings will provide a theoretical foundation for the utilization of ultrasound in enhancing the emulsifying properties of ZSP and promoting its application in the field of food processing.

In the present study, modified polyporous magnetic cellulose beads (PMCBs) were synthesized by several organic amines (EDA, DETA, TETA and AST) grafting PMCBs and then utilized as a new kind of support to immobilize Candida antarctica lipase B (CALB) for biodiesel production. The immobilized lipase catalysts based on PMCBs were characterized by Fourier transform infrared and scanning electron microscopy. The results showed that PMCBs-DETA was a more suitable immobilization support and the catalytic activity of immobilized lipases could reach 1.0 U/mg. Then the synthesized catalyst of CALB-PMCBs-DETA was used to produce biodiesel from Yellow horn seed oil via transesterification reaction. A high biodiesel yield (92.3%) was obtained under the optimal reaction conditions and the main compositions of the prepared biodiesel were tested by GC-MS. Moreover, the catalyst of CALB-PMCBs-DETA could be removed easily by a magnet and recycled at least 5 times. As a new kind of support, the modified PMCBs could be a promising alternative for the carriers of immobilizing enzymes used for the green and efficient production of biodiesel.
