Cationic liposomes (CLs) are novel nonviral vectors widely used for delivering drugs or genes. However, applications of CLs are largely hampered by their cytotoxicity, partly because the potential mechanism underlying the cytotoxicity of CLs remains unclear. The aim of the present study was to explore the underlying mechanism of cytotoxicity induced by CLs on HepG2 cells. Differential metabolites were identified and quantified using ultra-liquid chromatography quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF/MS). The toxicity of CLs on HepG2 cells was evaluated by multivariate data analysis and statistics. Additionally, CCK-8 assay, heatmap, pathway and co-expression network were carried out to explore the relations between the metabolites and the pathways. The results showed a dose-dependent toxic effect of CLs on HepG2 cells, with an IC 50 value of 119.9 μg/mL. Multivariate statistical analysis identified 42 potential metabolites between CLs exposure and control groups. Pathway analysis showed significant changes in pathways involving amino acid metabolism, energy metabolism, lipid metabolism and oxidative stress in the CLs exposure group vs the control group. Metabolites related to the above-mentioned pathways included phenylalanine, methionine, creatine, oxalacetic acid, glutathione, oxidized glutathione, choline phosphate and several unsaturated fatty acids, indicating that cells were disturbed in amino acid metabolism, energy and lipid supply when CLs exposure-induced injury occurred. It is concluded that CLs may induce cytotoxicity by enhancing reactive oxygen species in vitro , affect the normal process of energy metabolism, disturb several vital signaling pathways and finally induce cell death.

Peanuts are a rich dietary source of lipids, which are essential for human health. In this study, the lipid contents of 13 peanut cultivars were analyzed using UPLC-Q-TOF-MS and GC–MS. The OXITEST reactor was used to test their lipid oxidation stabilities. A total of 27 subclasses, 229 individual lipids were detected. The combined analysis of lipid and oxidation stability showed that lipid unsaturation was inversely correlated with oxidation stability. Moreover, lipid profiles differed significantly among the different peanut cultivars. A total of 11 lipid molecules (TG 18:2/18:2/18:2, TG 24:0/18:2/18:3, TG 20:5/14:1/18:2, TG 18:2/14:1/18:2, PE 17:0/18:2, BisMePA 18:2/18:2, PG 38:5, PMe 18:1/18:1, PC 18:1/18:1, MGDG 18:1/18:1, TG 10:0/10:1/18:1) might be employed as possible indicators to identify high oleic acid (OA) and non-high OA peanut cultivars, based on the PLS-DA result of lipid molecules with a VIP value greater than 2. This comprehensive analysis will help in the rational selection and application of peanut cultivars.Keywords:peanuts;oleic acid;lipidomics;oxidation stability

Pomegranate peel (PoP) is a valuable by-product rich in phenolic compounds with strong antioxidant potential. This study applied mechanochemical-assisted extraction (MCAE) to recover phenolics efficiently from PoP using eight solid reagents. The extraction parameters were optimized through response surface methodology based on a central composite design. Ultra-performance liquid chromatography coupled with triple time-of-flight mass spectrometry (UPLC-Triple-TOF/MS) tentatively identified twelve major phytochemicals. These phytochemicals include hydrolysable tannins, flavonoids, and phenolic acids. The optimal MCAE conditions were a liquid–solid ratio of 50 mL/g, an extraction temperature of 78 °C, and an extraction time of 67 min. Under these conditions, a total of 12 phytochemicals were identified and the total phenolic content reached 258.09 ± 1.35 mg GAE/g dry weight. The extract exhibited high antioxidant capacity (DPPH of 526.54 ± 13.38 μmol TE/g DW, ABTS of 1315.65 ± 15.16 μmol TE/g DW, FRAP of 798.57 ± 11.30 μmol TE/g DW, and RA of 1353.87 ± 23.43 μmol TE/g DW) and strong inhibitory activity against α-glucosidase and α-amylase. These results demonstrate that MCAE represents an eco-friendly and cost-effective technique for recovering bioactive phenolic compounds from PoP, offering promising applications as natural antioxidants and enzyme inhibitors in functional food formulations, providing new opportunities for the food industries. These findings provide a new strategy for valorizing agricultural by-products into functional ingredients for food applications.

Recently, fragrance ingredients have attracted increasing attention due to their imperceptible risks accompanying the comfortable feeling. To understand transformation mechanisms and toxicity evolution of benzyl formate (BF) in environment, its photochemical degradation in water was thoroughly studied herein. Results showed that 83.5% BF was degraded under ultraviolet (UV) irradiation for 30 min. Laser flash photolysis and quenching experiments demonstrated that triplet excited state ( 3 BF*), O 2 •− , and 1 O 2 were three main reactive species found during BF photodegradation. Eight degradation intermediates, including benzaldehyde, benzyl alcohol, o-cresol, bibenzyl, benzyl ether, 1,2-diphenylethanol, benzoic acid, and benzylhemiformal, were mainly formed as identified by LC-Q-TOF/MS and GC-MS analyses. Furthermore, the degradation mechanism was explained as the bond cleavage of 3 BF* and BF •+ , O 2 •− / 1 O 2 oxidation, e aq − reduction, and • OH addition reactions. Aquatic assessment suggests that except benzyl alcohol, benzoic acid, and benzylhemiformal, all the products were persistent and could result in increased aquatic toxicity compared to original BF. Consequently, these degradation products may cause more toxicity to organisms if they remain accumulated in water environment for a long time.

Background Honey-fried Licorice (HFL) is a dosage form of Glycyrrhizae Radix et Rhizome processed with honey, which has been recorded to exhibit better efficacy in tonifying the spleen compared to the raw product. In contrast, different processing methods of Glycyrrhizae Radix et Rhizome exhibit different efficacies and applications, but their current quality control index components remain consistent. Purpose Based on the discovery and research strategy of traditional Chinese medicine decoction piece quality marker (Q-marker), this study aimed to conduct a multidimensional integration of constituents absorbed into the body and metabolomics based on the tonifying spleen and stomach effects of HFL to effectively identify the Q-marker of HFL. Methods In this study, a spleen deficiency rat model was established using the "exhausted swimming + poor diet" method to investigate the pharmacodynamics of tonifying the spleen and stomach by HFL. The constituents absorbed into blood was conducted using UPLC-Q-TOF/MS, correlation analysis between metabolomics and constituents absorbed into blood recognized the Q-Marker of HFL. Results The pharmacodynamic data demonstrated that HFL exhibited a significant regulatory effect on the disordered levels of PP, trypsin, chymase, PL, α-Glu, MTL, GAS, VIP, IL-2, IFN-γ, and IgA in the spleen deficiency model. Furthermore, HFL was found to improve the pathological changes in the spleen and intestine in the spleen deficiency model, highlighting its significant "tonifying spleen and stomach" effect. In the serum containing HFL, a total of 17 constituents were identified as being absorbed into the blood. Among these, 11 were prototypical components, while 6 were metabolites. Metabolomics data revealed that 9 differentially expressed metabolic markers were observed. Furthermore, the analysis of endogenous metabolic markers indicated that 10 components exhibited significant correlations with these biomarkers. Conclusion The effect of "tonifying spleen and stomach" of HFL is closely related to the regulation of the material and energy metabolism pathway. The Q-Marker of HFL is glycyrrhizic acid and 18 β -glycyrrhetinic acid as the main control standards and liquiritin, isoliquiritin, liquiritin, isoliquiritin, isolicorice flavonol, licorice chalcone C and Formononetin were used as auxiliary standards.

Insomnia is an accompanying symptom of many diseases and is closely associated with neurodegenerative diseases. Naoling Pian (NLP) is a patented Chinese medicine mainly used to treat insomnia. To evaluate the sedative and hypnotic effects of NLP and its modulatory effects on biological metabolites and metabolic pathways, rats with p-chlorophenylalanine (PCPA)-induced insomnia were given different doses of NLP by oral gavage for seven days. Diazepam (DZP) served as a positive control. Behavior was measured using the open field test, and neurotransmitter levels in the brain tissue related to sleep were measured using ELISA. The metabolic profiles and biomarkers of PCPA-induced insomnia in rats before and after NLP administration were analyzed using UPLC-Q/TOF-MS combined with multivariate data analysis. The results showed that the levels of 5-hydroxytryptamine, gamma-aminobutyric acid, norepinephrine, and dopamine in the brain tissue were significantly recovered in the NLP treatment groups, demonstrating similar or even superior therapeutic effects compared to the DZP group. The behavior of the PCPA-model rats partially recovered to normal levels after seven days of treatment. Metabolomics identified 30 metabolites in the urine as potential biomarkers of insomnia, and NLP significantly altered 25 of these, involving 21 metabolic pathways. NLP has a remarkable effect on insomnia, the therapeutic effects of which may be largely due to the rectification of metabolic disturbances. This is the first study of the sedative and hypnotic effects of NLP from a metabolomic perspective.

Fructus Corni (FC), as a promising Chinese medicinal herb, has aroused considerable interest. Generally, FC needs to be processed according to the limited standard policy in China before clinical application, while the investigations on the specific processing methods (such as wine steaming or high-pressure wine steaming) are unclear. A comprehensive metabolomics strategy based on integrated non-targeted metabolomics and targeted glycomics in this paper was implemented to investigate the influences of the different processing technologies such as steaming, wine steaming, high-pressure steaming, high-pressure wine steaming, wine immersion, and wine stir-frying on FC, respectively. UHPLC-Q-TOF-MS/MS was employed for identifying and distinguishing the secondary metabolites. A total of 85 components were identified in all groups. The results of PCA score plots showed that the crude and processed samples had a complete separation, and wine steamed and high-pressure wine steamed samples could be a category, indicating that the two processed products had a similar quality. Multiple chromatography including HPLC (C 18 )-PDA, HPLC (NH 2 )-ELSD, and HPGPC-ELSD was used for determining the molecular weight distributions, the monosaccharide compositions of polysaccharides, and the contents of free monosaccharides and oligosaccharides. The results indicated that the content and composition of saccharides were different in crude and different processed FC. The polysaccharides were composed of fucose, arabinose, galactose, glucose, galacturonic acid, mannose and rhamnose, and the free monosaccharides were composed of fucose, arabinose, galactose, glucose, mannose, rhamnose and fructose in all FC samples. The PCA score plots of the glycomics indicated that the crude and high-pressure wine steamed FC could be a category, showing that the two groups had similar chemical compositions. Ultimately, the simulation processing experiments indicated that the transformation of morroniside, polysaccharides, oligosaccharides, fructose, and glucose to 5-HMF through the reactions of dehydration and deglycosylation was the potential mechanism of enhancing the effects by processing. Conclusionly, the saccharides should be investigated as thoroughly as the secondary metabolites, and the high-pressure wine steamed FC could be an alternative to wine steamed FC.

Network pharmacological analysis of RGG was performed based on HPLC-Q-TOF-MS/MS. • RGG alleviates liver fibrosis and suppresses hepatic stellate cell activation. • RGG exerts anti-fibrotic effects through autophagy mediated by the PTEN/AKT/mTOR signaling pathway. To clarify the bioactive constituents and anti-fibrotic mechanisms of Rougan Granules (RGG), this study utilized HPLC-Q-TOF-MS/MS to identify its chemical profile, followed by network pharmacology and molecular docking to explore potential targets. In vivo, RGG was administered at different doses to mice with carbon tetrachloride (CCl 4 )-induced liver fibrosis. The attenuation of liver injury by RGG was evaluated via serum biochemical profiling, histological staining, and western blot analysis. In vitro, platelet-derived growth factor-BB (PDGF-BB) was used to activate LX-2 cells, and the mechanisms of RGG in suppressing hepatic stellate cell (HSC) activation were validated via immunofluorescence and western blot. Furthermore, autophagic flux was monitored using laser scanning confocal microscopy in LX-2 cells transfected with mRFP1-EGFP-LC3B lentivirus. A total of 120 chemical constituents were identified, with network pharmacology analysis indicating that quercetin, genistein, and kaempferol might serve as the primary bioactive components of RGG. Functional enrichment analysis revealed that common targets were significantly enriched in the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) signaling pathway. Molecular docking confirmed that these key components exhibited stable binding affinities for phosphatase and tensin homolog (PTEN) and AKT1. Both in vivo and in vitro experiments validated that RGG upregulates PTEN expression to inhibit the AKT/mechanistic target of rapamycin (mTOR) signaling pathway. Furthermore, RGG was shown to exert anti-fibrotic effects by inducing HSC autophagy through the modulation of this pathway. These findings reveal that RGG attenuates liver fibrosis via PTEN/AKT/mTOR-mediated autophagy, supporting its therapeutic potential.

Guishao Yigong Decoction (GYD), a classic prescription that tonifies the spleen and qi, has been used in clinical practices for thousands of years to treat spleen deficiency. However, its in vitro and in vivo metabolic characteristics are still unclear. In this study, a rapid and reliable analytical method based on ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) with automated data processing (MetaboLynx) was established to investigate the metabolites and metabolic pathways of GYD in vivo and in vitro . Based on the characteristics of protonated ions, eleven precursors (ginsenoside Re, ginsenoside Rg1, ginsenoside Rb1, atractylenolide I, atractylenolide III, paeoniflorin, glycyrrhizic acid, pachymic acid, liquiritin, nobiletin, and ferulic acid) and their corresponding metabolites were detected and tentatively identified. A total of 81 metabolites were identified, including 53 metabolites in vivo , 40 metabolites of liver microsomes, and 43 metabolites of intestinal flora in vitro . Distinct metabolic patterns were observed between intestinal flora and liver microsomes - the former primarily catalyzed phase I transformations (hydroxylation, methylation, dehydroxylation, demethylation, and reduction), while the latter also executed phase II metabolism, with glucuronidation being the predominant conjugation reaction. The metabolic profiling and pathways of active components in GYD were systematically analyzed, which was helpful in clarifying its potential mechanism and clinical application.

In the present study, magnetic beads (MBs) conjugated with multiple monoclonal antibodies were constructed for capturing bacteria from food matrices. Escherichia coli ( E. coli ), Klebsiella pneumoniae , and Vibrio parahaemolyticus were taken as model bacteria, and multi-antibodies functionalized MBs (multi-Abs@MBs) were utilized for their capture. The excellency of the specificity and reproducibility of the present protocol was demonstrated by capturing E. coli , K. pneumoniae , and V . parahaemolyticus from water medium, and blood clam ( Scapharca subcrenata ) protein extracts, respectively. The presence of 10 CFU/mL of bacteria is still detectable. The prepared multi-antibodies functionalized MBs remain effective for bacterial capture after 1 day of storage at 4 °C. The multi-Abs@MBs successfully sensed E. coli and V . parahaemolyticus from fresh blood clam muscle tissue sample. The present protocol is expected to be applied in bacterial analysis of protein foods to guide their safe consumption.

Protein N-glycosylation, as one of the most crucial post-translational modifications, plays a significant role in various biological processes. The structural alterations of N-glycans are closely associated with the onset and progression of numerous diseases. Therefore, the precise and specific identification of disease-related N-glycans in complex biological samples is invaluable for understanding their involvement in physiological and pathological processes, as well as for discovering clinical diagnostic biomarkers. However, protein N-glycosylation suffers from microscopic heterogeneity and low abundance in biological systems, leading to N-glycopeptide signals being overshadowed by those of their non-glycosylated counterparts during mass spectrometry (MS) analysis. Consequently, there is an urgent demand for the development of novel methods for highly efficient N-glycan enrichment. In this study, we introduced a novel hydrophilic nanomaterial, nitrogen-modified reduced graphene oxide (N-rGO), tailored for this purpose, which was formed by a condensation reaction between the amino groups of rGO and the carboxyl groups of Fmoc-Photo-Linker. Compared to other enrichment materials, N-rGO not only supports efficient N-glycans enrichment via hydrophilic interaction (HILIC), but also serves as an effective matrix for direct MALDI-TOF MS analysis combined with DHB, thereby avoiding sample loss during N-glycans release. 76 and 81 serum N-glycans were obtained from 3 healthy individuals and 3 hepatocellular carcinoma (HCC) patients. Notably, relative quantification of serum N-glycans between 20 patients and 20 healthy controls showed significant expression differences, such as H5N4F1S1, H6N5F1, H5N4S2, H5N4F2S1 and H5N5F1S1, indicating the potential of N-rGO for biomarker discovery.
