The study explored the chemical, antimicrobial, and antioxidant properties of essential oils from garlic (GEO), parsley (PEO), and thyme (TEO) using GC-MS, ATR-FTIR, and DSC techniques, and examined the synergistic effects of their combination on antioxidant and antimicrobial properties. The oils' antimicrobial effectiveness against pathogens was also tested. GC-MS analysis revealed diverse chemical profiles. The garlic, thyme, and parsley mixture (GTP) showed the highest phenol content (533.05 milligrams of gallic acid equivalent per 100 grams of dry weight sample), flavonoids (284.16 milligrams of quercetin equivalent per 100 grams of dry weight sample), and antioxidant activity (94.14% DPPH scavenging). The oils demonstrated significant antimicrobial effects, particularly against gram-negative bacteria and molds, with the GTP mixture being highly effective against Aspergillus niger . The bioactive compounds and antimicrobial effects were ranked as GTP > GT > GP > TP > GEO > TEO > PEO. These findings suggest that combining these EOs enhances their bioactivity, positioning them as natural preservatives for food safety and shelf-life extension.

Metapanax delavayi is widely consumed as a vegetable and herbal tea in western China; however, the impact of postharvest drying on its chemical composition and bioactivity remains insufficiently characterized. In this study, the effects of three drying methods-shade drying (SD), hot-air drying (HAD), and vacuum freeze-drying (VFD)-on the metabolite profile and antioxidant activity of M. delavayi were systematically investigated using UHPLC-Q-TOF-MS and GC–MS/MS-based untargeted metabolomics, combined with multivariate statistical analysis and KEGG pathway enrichment. A total of 742 non-volatile and 87 volatile differential metabolites were detected across the drying treatments, indicating pronounced processing-induced metabolic alterations. KEGG enrichment analysis revealed that the differential metabolites were mainly associated with flavonoid biosynthesis, amino acid metabolism, galactose metabolism, and glycolysis/gluconeogenesis. Antioxidant assays (DPPH, ABTS, hydroxyl radical scavenging activity, and FRAP) demonstrated significant differences among drying methods, with VFD-treated samples generally exhibiting higher antioxidant capacity. Correlation analysis suggested that phenolic and flavonoid metabolites were major contributors to antioxidant activity. Overall, compared with SD and HAD, VFD showed a greater capacity to preserve phytochemical composition and antioxidant potential. These findings provide a scientific basis for optimizing drying strategies and improving the quality of M. delavayi -derived products.

BackgroundPrimary dysmenorrhea (PDM) is a prevalent menstrual disorder among women, often underreported and undertreated. Wen-Jing-Zhi-Tong Decoction (WJZTD), a patented Traditional Chinese Medicine (TCM) herbal decoction, has shown efficacy in treating PDM. However, the underlying therapeutic mechanism of WJZTD in PDM treatment remains to be elucidated.ObjectiveThis study aimed to employ integrative pharmacology and experimental validation to investigate the potential therapeutic mechanisms of WJZTD in treating PDM.MethodsThe bioactive compounds of WJZTD were identified by UPLC-Q-Exactive-Orbitrap MS/MS and GC-MS. Putative targets of WJZTD were obtained from Swiss Target Prediction, STITCH, and BATMAN-TCM databases. Known targets of PDM were retrieved from Gene Cards and Drug Bank databases. Protein-to-protein interactions were constructed to screen key targets using the STRING database. Subsequently, GO and KEGG pathway enrichment analyses were performed based on Metascape. Finally, a PDM rat model was established to validate the potential therapeutic mechanisms of WJZTD using Western Blot, PCR, and ELISA.Results390 bioactive compounds in WJZTD were identified through UPLC-Q-Exactive-Orbitrap MS/MS and GC-MS. Network pharmacology revealed 7 key compounds with 20 targets and pathways that are crucial for WJZTD in treating PDM. Behavioral tests confirmed that WJZTD can effectively ameliorate menstrual pain in PDM. WJZTD also inhibited prostaglandin production, thereby relieving uterine smooth muscle contraction. The downregulation of the BDNF/TrkB/ERK/CREB signaling pathway, identified as the key target and pathway through network pharmacology, may be crucial to the anti-nociceptive and anti-inflammatory effects of WJZTD in treating PDM.ConclusionThis study provides the first comprehensive analysis of the key compounds, targets, and pathways of WJZTD, laying a solid foundation for future pharmacological studies on PDM. The anti-nociceptive and anti-inflammatory effect may be attributed to the downregulation of the BDNF/TrkB/ERK/CREB signaling pathway.

Artemisiae Argyi Folium (AAF) is a medicinal and edible herb whose quality is dependent on its geographical origin and aging years. This study employed untargeted metabolomics based on GC–MS and UHPLC-HRMS to identify its geographical origin and aging years. First, we employed our proprietary AntDAS platform to fully analyze the mass spectrometry data and screen for key differential metabolites. Analysis identified 58 geographical origin-related metabolites (35 non-volatile and 23 volatile). Notably, the chemical profiles of the two Dao-di production regions differed markedly. Samples from Nanyang (Henan) were characterized by high abundances of endo -borneol, terpinen-4-ol, eucalyptol, 3,4-dicaffeoylquinic acid, phellopterin, and quercetin, whereas these compounds were found in low abundance in samples from the other Dao-di production region, Qichun (Hubei). Furthermore, 27 metabolites with aging-year differences were identified, comprising 18 non-volatile and 9 volatile compounds, and the aged AAF compared to fresh AAF showed significantly enriched chemical components. Regarding the aging effect, the contents of eucalyptol and 5-methyl-decane were highest in the 5-year samples. Endo -borneol showed higher levels in both 1-year and 5-year samples, with its content in 3-year samples being intermediate. In contrast, n-hexadecanoic acid and phytol were more abundant in samples aged for over 5 years. Finally, using these differential metabolites, OPLS-DA models achieved 100.0% accuracy in geographical origin classification and over 94.4% accuracy for aging year discrimination. This study provides a chemical basis for the geographical origin traceability and aging year identification of food-drug homologous products.

To unveil the nitrogen migration and conversion characteristics, catalytic copyrolysis of biomass pseudo components and polyamide (PA) with different blend ratios (1:0, 5:1, 3:1, 1:1, 1:3, 1:5, 0:1) under an ammonia atmosphere was proposed to boost the yield of N-containing compounds (NCCs) and N-rich biochar. The evolution and distribution of NCCs in liquid, gas and biochar were systematically investigated with a combination of TG-MS, Py-GC/MS and EPR. Synergistic effects and possible reaction pathways were also evaluated. Experimental results showed that PA could obviously boost biomass conversion due to increasing the chance of secondary cleavage, and the comprehensive synergistic effect of biomass-derived H* radicals, acid sites of the catalyst and cracking reactions (-C-N and C-C bonds) that reduced the reaction energy barrier and enhanced the NH 3 and HCN yields. NH 3 comes from the amino acids that are released from the amino acid pyrolysis and hydrolysis of HCN on the surface of char, while HCN is from the secondary cracking of primary pyrolysis products. Adding biomass increased CO 2 , CO, CH 4 , C-O and C O emissions from co-pyrolysis. Additionally, significant synergetic effects were observed when Biomass/PA= 3:1, which improved the NCCs and pyridine yields by 78.58% and 48.23%, respectively, under the HZSM-5 catalyst. A lower proportion of PA addition facilitated the Maillard reaction and amide bond cleavage to enhance the NCCs content and suppressed π-conjugated ring structure compound evolution and coke-derived O-containing compound polymerization, while a higher content of PA was favorable for amine and diaza heterocycle compound formation. Moreover, the addition of PA reduced the HHV and N content in biochar, resulting in lower pyrrole-N content and graphitization degree due to secondary cross-polymerization reaction of reaction volatiles, but it enhanced the polarity due to higher oxygen content (14.98%).

Agastache rugosa (AR) is a wildly cultivated medicinal and aromatic crop, which usually recommended to be harvested when the plant is exuberant with not flowering or in full flower stage. But there is no scientific basis for the support of the cognition. Therefore, the accumulation patterns of major active components during flower development (inflorescences with buds, full bloom and after full bloom stages) in two chemotypes (menthone type and estragole type) of AR were investigated by newly developed GC–QQQ–MS/MS and UPLC–QTOF–MS/MS methods. Five volatile (pulegone, menthone , estragole, methyleugenol and β -caryophyllene) and nine non-volatile components (rosmarinic acid, tilianin, acacetin 7- O -(6"- O -malonyl)- β - D -glucopyranoside, apigenin , agastachoside, isoagastachoside, acacetin 7- O -(2"- O -acetyl-6"- O -malonyl)- β - D -glucopyranoside, cirsimaritin and acacetin) in two chemotypes of AR samples at three stages were simultaneously quantified. It was found that the relatively higher contents of main volatile components were present in menthone type of AR collected at the full flower stage and in estragole type of AR at the after full bloom stage, whereas the relatively higher contents of main non-volatile components were present in menthone type of AR collected at the inflorescences with buds stage and in estragole type of AR at the after full bloom stage. Considering major active volatile and non-volatile components with higher levels, full bloom stage and after full bloom stage should be optimal harvesting time for menthone type and estragole type of AR, respectively.

This study focused on characterizing the volatile profiles and contributing compounds in pan-fried steaks from different Chinese yellow cattle breeds. The volatile organic compounds (VOCs) of six Chinese yellow cattle breeds (bohai, jiaxian, yiling, wenshan, xinjiang, and pingliang) were analyzed by GC-Q-Orbitrap spectrometry and electronic nose (E-nose). Multivariate statistical analysis was performed to identify the differences in VOCs profiles among breeds. The relationship between odor-active volatiles and sensory evaluation was analyzed by partial least square regression (PLSR) to identify contributing volatiles in pan-fried steaks of Chinese yellow cattle. The results showed that samples were divided into two groups, and 18 VOCs were selected as potential markers for the differentiation of the two groups by GC-Q-Orbitrap combined multivariate statistical analysis. YL and WS were in one group comprising mainly aliphatic compounds, while the rest were in the other group with more cyclic compounds. Steaks from different breeds were better differentiated by GC-Q-Orbitrap in combination with chemometrics than by E-nose. Six highly predictive compounds were selected, including 3-methyl-butanal, benzeneacetaldehyde, 2-ethyl-6-methyl-pyrazine, 2-acetylpyrrole, 2-acetylthiazole, and 2-acetyl-2-thiazoline. Sensory recombination difference and preference testing revealed that the addition of highly predictive compounds induced a perceptible difference to panelists. This study provides valuable data to characterize and discriminate the flavor profiles in pan-fried steaks of Chinese yellow cattle.Keywords:Chinese yellow cattle;volatile organic compounds;GC-Q-Orbitrap;E-nose;sensory evaluation;multivariate statistical analysis

Benzo[a]pyrene (BaP) is a kind of trace pollutant commonly found in environment, food, and organism. It has been widely concerned because of its strong carcinogenicity to the human body. In this paper, covalent organic framework TpBD, in situ growth on titanium wire, was used as the coating of solid-phase microextraction (SPME) fiber and coupled with gas chromatography–flame ionization detector (GC-FID) for the detection of trace BaP in roast meat samples. The linear range of the developed method under the optimized experimental conditions was 0.02–15 μg L −1 , the detection limit (S/ N = 3) was 0.006 μg L −1 , and the limit of quantification (S/ N = 10) was 0.02 μg L −1 . The intra-day and inter-day precision of a single fiber were 1.73% and 2.27%, respectively. The relative standard deviation (RSD) between fiber-to-fiber was investigated by three as-fabricated fibers was 6.09%. Moreover, the enrichment factor of the fabricated TpBD SPME fiber for BaP was 4914, and the fiber can withstand at least 150 cycles of adsorption and desorption without significantly decrease in extraction efficiency (< 3.6%). Finally, the developed method was successfully applied to the detection of BaP in roast meat samples with the recoveries from 95.4 to 108.5%.

Lard imparts unique organoleptic properties that underpin its essential role in Chinese gastronomy; however, the specific lipid precursors contributing to its aroma remain unclear. This study explores the flavor formation mechanism of lard by comparing its texture and aroma at two preparation temperatures, 130 °C and 100 °C. We identified a total of 256 and 253 lipids at these temperatures, respectively, with triacylglycerols (TGs) and diacylglycerols (DGs) being the predominant lipid species. An HS-GC-IMS analysis detected 67 volatile compounds, predominantly aldehydes, acids, and alcohols. A subsequent Orthogonal Partial Least Squares-Discriminant Analysis (OPLS-DA) identified 49 discriminatory lipids and 20 differential volatiles. A correlation analysis showed a positive relationship between aldehydes and unsaturated triglycerides in lard, with TG (16:1-16:1-18:0), TG (17:2-18:1-18:1), TG (16:1-17:1-18:1), and TG (18:1-18:1-20:1) identified as characteristic markers at both temperatures. Furthermore, there was a positive correlation between ketones and alcohols and phospholipids and sphingolipids containing unsaturated fatty acid chains. TGs and glycerophospholipids (GPs), rich in polyunsaturated fatty acids, are likely key precursors driving the formation of distinct flavors during lard processing. This study elucidates the mechanistic interactions between lipids and volatile organic compounds, providing a framework for optimizing lard processing protocols and flavor modulation.

Covalent organic framework TpBD was grafted on stainless steel wire with polydopamine as a linker. The fabricated TpBD bonded stainless steel wire was used as the solid-phase microextraction fiber to extract sixteen polycyclic aromatic hydrocarbons (PAHs) for subsequent GC-MS/MS determination in grilled meat samples. The developed method gave the limits of detection ( S/N = 3) from 0.02 (pyrene)-1.66 (naphthalene) ng L −1 and enhancement factors from 1069 (naphthalene)-10879 (benz(a)anthracene). The relative standard deviations (RSDs) for intra-day and inter-day study are in the range of 2.6%–8.5% and 4.5%–9.4%, respectively. The fiber-to-fiber RSDs for three parallel prepared fibers were 5.3%–10.0%. One TpBD bonded fiber can stand at least 200 cycles without significant loss of extraction efficiency. The developed method was successfully applied for the determination of trace PAHs in grilled meat samples with recoveries from 85.1% to 102.8%.

The herbal tea made from the leaves and stems of Cyclocarya paliurus is thought to be more flavorful than those made from the leaves only. However, evidence supporting this view is not available yet. 53 VOCs and 54 non-VOCs were identified via HS-SPME-GC-MS and UPLC-Q-TOF/MS, respectively, which were found to vary dramatically in three groups of samples (combination of stems and leaves, separated leaves, and separated stems). 11 VOCs and 18 non-VOCs potential markers are responsible for the change of metabolic effects through the biosynthesis of flavonoids, the synthesis of terpenoids, and the oxidation of fatty acids and carotenoids. In response, the stems were effective to enhance fatty odors, the initial astringency and bitterness and the aftertaste of sweetness of the leaves. Stems are conducive to increasing total phenolic content, total flavonoid content and antioxidant capacity of Cyclocarya paliurus herbal extract because of the increase in polyphenols. In addition, the stems have the potential to be used as raw materials for nerolidol and polyphenols extraction. This study has been the first to determine the contribution of stem to the flavor of Cyclocarya paliurus herbal tea and these results provide the theoretical basis for making Cyclocarya paliurus herbal tea with stems.

Semen Cuscutaeis commonly used as a medicinal and edible functional food ingredient. Salt-processing can significantly alter its sensory quality and endogenous components. Currently, salt-processedSemen Cuscutaemainly adopts hyperoside as the quality evaluation indicator, which fails to meet the requirements for the identification of processing intensity (heat level) during the development of the traditional Chinese medicine industry. This study aims to construct a comprehensive quality evaluation framework for identifying the optimal processing degree of salt-processedSemen Cuscutae. Multi-dimensional bionic technologies including machine vision, electronic nose and electronic tongue, combined with HPLC and GC-IMS, were applied to analyze the changes in sensory characteristics and endogenous components of salt-processedSemen Cuscutaeacross different processing degrees. Characteristic indicators were comprehensively scored using the AHP-TOPSIS method. Compared with other groups, appropriately processed salt-processedSemen Cuscutaeexhibited a brown appearance, significantly different W1W/W2W sensor responses, resulting in a more harmonious taste profile and distinct volatile chemical markers. Further correlation analysis was performed among bionic sensing indicators, endogenous components and GC-IMS-derived volatile data. AHP-TOPSIS results demonstrated that salt-processedSemen Cuscutaewith an appropriate processing degree exhibits optimal comprehensive quality. The comprehensive quality evaluation framework established in this study provides scientific support for the process control and quality assessment ofSemen Cuscutaeas a functional food ingredient, and also offers a methodological reference for the processing evaluation of similar medicinal and edible food materials.
