Cyclocarya paliurusis an edible and medicinal plant containing various bioactive components with significant health benefits. A combinative method using high-performance liquid chromatography (HPLC) fingerprint and quantitative analysis was developed and successfully applied for characterization and quality evaluation ofC. paliurusleaves collected from 18 geographical locations of China. For the fingerprint analysis, 21 common peaks were observed among the 18 samples, and these peaks were identified by high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (HPLC–Q–TOF–MS), while a simultaneous quantification of 16 markers was conducted to interpret the variations of contents of these bioactive compounds among theC. paliurusleaves from different geographical locations. Quantification results showed that the contents of these sixteen investigated compounds varied greatly among the leaves from different locations. The developed new method would be a valuable reference for further study and development of this bioactive plant.Keywords:Cyclocarya paliurus;fingerprint;HPLC–Q–TOF–MS;quantitative analysis;quality evaluation

Background: Panax ginseng Meyer which has been cultivated and grown naturally in mountainous forests is formally called “Lin-Xia-Shan-Shen” (LXSS), but when cultivated it is called garden ginseng (GG), according to the Chinese Pharmacopoeia (2015 edition). The medicinal value of LXSS is significantly higher than that of GG based on the clinical experience of TCM. This study aimed to evaluate the variety of chemical constituents in LXSS and GG. Methods: 18 LXSS and 6 GG samples were investigated using a UPLC-Q-TOF-MS technique. Results: the contents of 16 metabolites, mainly involved in the biosynthesis of rare ginsenosides (ginsenosides Rg3, -Rh1, -Rh2), galactose metabolism (myo-inositol), the citric cycle (citric acid and succinic acid), GABA shunt (GABA) and amino metabolism (alanine and aspartic acid), were higher in LXSS than in GG; while 14 metabolites, mainly involved in starch and sucrose metabolism (fructose and sucrose), amino metabolism (tryptophan, proline, dencichine and pyroglutamic acid) and campesterol biosynthesis (campesterol), were lower in LXSS than in GG. For LXSS with different growing years, 5 metabolites showed a tendency to increase dependent on the number of years, and these were related mainly to galactose metabolism (melibiose), the citric cycle (malic acid), fatty acid metabolism (2-hydroxy stearic acid); while 5 metabolites showed a tendency to decrease on ascending the grades, and these were related to sucrose metabolism (fructose and sucrose), fatty acid metabolism (2-hydroxy hexadecanoic acid) and campesterol biosynthesis (campesterol). Conclusion: this proposed analytical method coupled with multivariate analysis is fast, accurate, and reliable for discriminating GG and high cultivation ages of LXSS samples.

This study investigated the therapeutic mechanism of Rehmanniae Radix Praeparata (RRP) in treating blood deficiency syndrome (BDS) through integrated chemical analysis and pharmacological validation. UPLC-Q-TOF-MS identified chemical components of Rehmanniae Radix (RR) and RRP, with network pharmacology analysis suggesting AKT1 and NOS3 in the PI3K-AKT pathway as potential therapeutic targets. Pharmacodynamic evaluations using ELISA, hematological analysis, histopathology, and immunohistochemistry demonstrated RRP’s efficacy in improving hematological parameters, energy metabolism, and organ pathology in BDS mice. Experimental validation via RT-qPCR and Western blot confirmed significant upregulation of AKT1 and NOS3 mRNA and protein expression following RRP treatment. The findings indicate that RRP alleviates BDS by activating the PI3K-Akt signaling pathway to modulate AKT1 and NOS3 expression, providing mechanistic insights into its therapeutic actions.

Amentoflavone, a biflavonoid occurring in many edible supplements, possesses some bioactivities, including antioxidant, anti-inflammation, antitumor, and neuroprotective activities. In the present study, an ultrahigh-performance liquid chromatography coupled to quadrupole time-of-flight tandem mass spectrometry (UHPLC-Q-TOF-MS/MS) method, combined with a three-step analytical strategy, was employed to identify metabolites in vivo (rat plasma, bile, urine, and feces) and in vitro (rat liver microsomes and rat intestine microsomes). A total of 39 metabolites in rats and nine metabolites in rat microsomes were elucidated by UHPLC-Q-TOF-MS/MS analysis, and the chemical structure of some isomers was further assigned by calculated Clog P values. Oxidation, internal hydrolysis, hydrogenation, methylation, sulfation, glucuronidation, glucosylation, O-aminomethylation, and degradation were the major metabolic pathways of amentoflavone. Noteworthy, O-aminomethylation and glucosylation could be considered as unique metabolic pathways of amentoflavone. This was the first report on metabolite identification of amentoflavone in vivo and in vitro, and the metabolic findings offer novel and valuable evidence for an in-depth understanding of the safety and efficacy of amentoflavone.

A rapid and efficient method for the identification of antioxidants in the traditional Chinese medicine Polygalae Radix (PR) by HPLC–ESI-Q-TOF-MS/MS is described. The method is based on the hypothesis that upon reaction of antioxidants with 1,1-diphenyl-2-picrylhydrazyl (DPPH), the peak areas of compounds with potential antioxidant activities in the HPLC chromatogram will be significantly reduced in comparison to the untreated sample. The identity confirmation was achieved by Q-TOF-MS/MS technique. With this method, eight components were proposed possessing potent antioxidant activity. They were identified as sibiricose A5, sibiricose A6, sucrose monoester, polygalaxanthone III, tenuifoliside B, 3',6-disinapoylsucrose (DISS), sucrose diester , tenuifoliside C, respectively. DISS was proposed to be the most potent one. The antioxidant activity of DISS was evaluated by DPPH, ABTS radical scavenging assay and ferric-reducing antioxidant power (FRAP) assay in vitro. Vitamin C (Vc) was used as positive control substance. DISS showed moderate DPPH (DISS's IC 50 value was 1024.17 μg/mL, Vc's was 294.68 μg/mL) and ABTS (IC 50 324.13 μg/mL, Vc's was 117.50 μg/mL) free radical scavenging capacity and ferric-reducing antioxidant power. DISS can be used as a new source of natural antioxidant in foods and cosmetics.

Poliumoside is representative of phenylethanoid glycosides, which are widely found in many plants. Poliumoside is also regarded as the main active component of Callicarpa kwangtungensis Chun (CK), though its oral bioavailability in rat is extremely low (0.69%) and its in vivo and in vitro metabolism has not yet been systematically investigated. In the present study, an ultra performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS) method was employed to identify the metabolites and investigate the metabolic pathways of poliumoside in rat after oral administration 1.5 g·kg –1 of poliumoside. As a result, a total of 34 metabolites (30 from urine, 17 from plasma, and 4 from bile) and 9 possible metabolic pathways (rearrangment, reduction, hydration, hydrolyzation, dehydration, methylation, hydroxylation, acetylation, and sulfation) were proposed in vivo . The main metabolite, acteoside, was quantified after incubated with rat intestinal bacteria in vitro . In conclusion, the present study systematically explored the metabolites of poliumoside in vivo and in vitro , proposing metabolic pathways that may be significant for further metabolic studies of poliumoside.

The present study aimed to investigate the effects of steamed notoginseng single-flavored medicine, herb pairs, compound medicine on anemia rats induced by N-acetyl phenyl hydrazine (APH) to explore the underlying hematinic regulation mechanisms. Rats were randomly divided into seven groups: control group (CG); model group (MG); positive control group (PCG); steamed notoginseng group (SNG); ginseng group (GG); herbal pair group (HPG) and compound prescription group (CPG). Day 12 of the experiment, the blood routine examination of the rats was measured. At the same time, the rats' plasma and urine samples were collected. An Ultra-performance Liquid Chromatography-Quadrupole-Time-of-Flight / Mass Spectrometry (UPLC-Q-TOF/MS) with unsupervised principal component analysis (PCA) and supervised partial least squares discriminant analysis (PLS-DA) combined analytical method was established for metabolomics study of steamed notoginseng . Compared with the CG, red blood cell (RBC) and hemoglobin (Hb) levels in the MG were significantly lower (P < 0.01). The results of blood routine examination show that the model of the rats with blood deficiency syndrome have successfully modelled. Compared with the MG, steamed notoginseng can significantly increase the RBC level of rats (P < 0.01), indicating that steamed notoginseng has the blood tonic effect. The related indicators of each administration group showed a good trend of returning to normal. 44 potential biomarkers for hemolytic anemia were screened from plasma and urine samples. Compared with the CG, there were down-regulation seven biomarkers in plasma of the MG, such as retinol, l -valine and arachidonic acid, and 14 biomarkers up-regulated such as protoporphyrin IX and nicotinamide; 28 metabolites such as proline, histidine, phenylalanine, l -arginine and l -tyrosine were up-regulated in urine of the MG. The metabolic level of biomarkers could be changed to a normal state after the rats were given steamed notoginseng , herb pairs, and compound prescriptions. It is presumed that steamed notoginseng plays a role in blood enriching through 12 metabolic pathways, including valine, leucine and isoleucine biosynthesis, phenylalanine, tyrosine and tryptophan biosynthesis, retinol metabolism and so on.

Currently, illegal addition of anti-infective drugs has been detected in some cosmetics to achieve rapid sterilization and anti-inflammatory effects. However, the abuse of anti-infective drugs may endanger the health of citizens. Thus, methods for the detection and quantitative determinations of such substances should be developed. In this paper, a method combining ultra-high-performance liquid chromatography with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF HRMS) was designed. Its significance and potential were verified by the identification, confirmation, and quantification of 37 illegally added anti-infective drugs in cosmetics that claimed to have anti-acne effects. The method validation revealed a satisfactory linear relationship, and each coefficient of determination ( r 2 ) was higher than 0.9943. The LOD and LLOQ results were in the ranges of 0.0003–0.1063 μg g −1 and 0.0012–0.3545 μg g −1 , respectively. The accuracy ranged from 70.8 to 122.8%, whereas the intra- and inter-day precisions were in the ranges of 0.2–12.8% and 0.2–13.8%, correspondingly. The mean recoveries were in the range of 70.1–117.7%, and the matrix effects ranged from 73.0 to 121.4%. Of the 200 batches of cosmetics that claimed to have anti-acne effects, three batches were positive, with chemical components such as metronidazole, lincomycin, clindamycin, tinidazole and miconazole nitrate being discovered. Therefore, the Q-TOF spectrometry could be widely applied in routine screening of adulteration in cosmetics.

Toxicodendron vernicifluum bark has been used for many years as a component in foods and as a traditional herbal medication. Unfortunately, the presence of urushiols, which induce allergies, limits its application. This study used a vortex-blending matrix solid-phase dispersion microextraction technique to extract urushiols from Toxicodendron vernicifluum bark. HPLC was used to evaluate the amounts of the extracted urushiols (15:0, 15:1, 15:2, and 15:3). The modified magnetic adsorbent was prepared through an in situ coprecipitation method and characterized using a variety of techniques. The optimized extraction conditions are as follows: using magnetic Zeolite Socony Mobil-Five as an adsorbent, a 1:2 sample/adsorbent ratio, 2.5 min of vortex-blending time, 4 mL of 0.1% (V/V) trifluoroacetic acid-methanol as the elution solvent and 8 min of ultrasound time. There was good linearity and high repeatability in the method. Furthermore, the limits of detection for the urushiols ranged from 0.20 to 0.50 μg/mL. Under the optimized conditions, 50 compounds were identified by ultra high performance liquid chromatography and quadrupole time-of-flight mass spectrometry. These compounds included 8 phenolic acids, 9 monomeric urushiols, 11 urushiol dimers, 10 other components, and 11 flavonoids. The suggested approach, which has the advantages of few stages and high extraction efficiency over existing extraction procedures, is a potentially useful method for obtaining and evaluating urushiols in raw materials or extracts.

Food fraud is common in the tuna industry because of the economic benefits involved. Ensuring the authenticity of tuna species is crucial for protecting both consumers and tuna stocks. In this study, GC-Q-TOF and UPLC-Q/Orbitrap mass spectrometry-based metabolomics were used to investigate the metabolite profiles of three commercial tuna species (skipjack tuna, bigeye tuna and yellowfin tuna). A total of 22 and 77 metabolites were identified with high confidence using GC-Q-TOF and UPLC-Q/Orbitrap mass spectrometry , respectively. Further screening via chemometrics revealed that 38 metabolites could potentially serve as potential biomarkers. Hierarchical cluster analysis showed that the screened metabolite biomarkers successfully distinguished the three tested tuna species. Furthermore, a total of 27 metabolic pathways were identified through enrichment analysis based on the Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathways.
