[PMID: 38347251 DOI: 10.1007/s00216-024-05177-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 01/19/2024] [Accepted: 01/24/2024] [Indexed: 02/29/2024]
Abstract
The processing of traditional Chinese medicine (TCM) plays an important role in the clinical application, which usually has the function of "increasing efficiency and reducing toxicity". Polygonum multiflorum (PM) has been reported to induce hepatotoxicity, while it is believed that the toxicity is reduced after processing. Studies have shown that the hepatotoxicity of PM is closely related to the changes in chemical components before and after processing. However, there is no comprehensive investigation on the chemical changes of PM during the processing progress. In this research, we established a comprehensive method to profile both small molecule compounds and polysaccharides from raw and different processed PM samples. In detail, an online two-dimensional liquid chromatography coupled with quadrupole-orbitrap mass spectrometry (2D-LC/Q-Orbitrap MS) was utilized to investigate the small molecules, and a total of 150 compounds were characterized successfully. After multivariate statistical analysis, 49 differential compounds between raw and processed products were screened out. Furthermore, an accurate and comprehensive method for quantification of differential compounds in PM samples was established based on ultra-high performance liquid chromatography/Q-Orbitrap-MS (UHPLC/Q-Orbitrap-MS) within 16 min. In addition, the changes of polysaccharides in different PM samples were analyzed, and it was found that the addition of black beans and steaming times would affect the content and composition of polysaccharides in PM significantly. Our work provided a reference basis for revealing the scientific connotation of the processing technology and increasing the quality control and safety of PM.

Fructo-oligosaccharide enhanced bioavailability of polyglycosylated anthocyanins from red radish via regulating gut microbiota in mice. Food Chem X 2023; 19:100765. [PMID: 37780282 PMCID: PMC10534114 DOI: 10.1016/j.fochx.2023.100765] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 06/12/2023] [Accepted: 06/18/2023] [Indexed: 10/03/2023] Open
Abstract
The anthocyanins from red radish (ARR) rich in polyglycosylated pelargonidin glucosides were used as pigment. However, bioavailability of anthocyanins was considered at low level. This work examined the intensive effects of fructo-oligosaccharide (FOS) on ARR bioavailability. Pelargonidin, cyanidin and pelargonidin-3-glucoside showed higher level in serum of mice fed with FOS together with ARR for 8 weeks than that fed with only ARR. Co-ingestion of FOS and ARR more effectively elevated the hepatic antioxidant activity by increase in total antioxidant capacity and activities of superoxide dismutase and glutathione peroxidase when compared with intake of ARR. FOS also markedly increased pelargonidin level in cecum of mice. 16S RNA sequencing found that Bacteroides genus play an important role in FOS elevating bioavailability of ARR. Fecal bacteria transplantation verified the positive effects of FOS on ARR bioavailability. These results suggested that combined ingestion of FOS and ARR is effective strategy for bioactivity of ARR.

Abstract
Genistein (GS), an isoflavone compound found in soybean, plays a neuroprotective role in Alzheimer's disease (AD). However, the mechanism of its action remains unclear. Herein, binding ability between GS and GRP78 was predicted by molecular docking, and the effect of GS in vivo and vitro were further studied. In this study, the effects of GS on learning and memory ability, changes of hippocampal neurons and ultrastructure of hippocampal CA3 region in AD rats were investigated. Besides, the protein or mRNA levels of the related proteins were detected. The results showed GS could effectively improve the learning and the memory ability, reduce the damage of hippocampal neurons, and decrease the protein or mRNA expression levels of GRP78, CHOP, Caspase-12, Cle-Caspase-9, Cle-Caspase-3, PERK, and p-PERK. Taken together, our data reveal GS has a neuroprotective effect by inhibiting the ERS-mediated apoptotic pathway, which may be a new therapeutic target for the treatment of AD.

Abstract
An efficient method based on ultrafiltration high-performance liquid chromatography coupled with photodiode array detector and electrospray ionization mass spectrometry for the rapid screening and identified of the ligands for activated from the extract of Trifolium repens L. Five major compounds, namely ononin, daidzein, genistein, formononetin, and biochanin A, were identified as potentially effective inhibitors. Subsequently, the specific binding ligands were separated by stepwise flow rate high-speed countercurrent chromatography and semipreparative high-performance liquid chromatography. This is the first report that T. repens extracts contain potent lipoxidase inhibitors. In summary, we systematically studied the active components in T. repens, evaluated their activity, separated and purified them, and identified their structure. This method is simple, fast, and efficient. It is suitable for the separation and purification of active compounds in T. repens, and provides a theoretical basis and technical platform for the development of natural medicines.

Rapid screening and purification of potential inhibitors from Medicago sativa by ultrafiltration-liquid chromatography combined with stepwise flow rate counter-current chromatography. PHYTOCHEMICAL ANALYSIS : PCA 2021; 32:382-394. [PMID: 32893385 DOI: 10.1002/pca.2985] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 08/12/2020] [Accepted: 08/13/2020] [Indexed: 06/11/2023]
Abstract
INTRODUCTION Medicago sativa contains flavonoids, saponins, coumarins, sterols, monoterpenes, and organic acids, with flavonoids being the main active constituents. Flavonoids naturally contain a 2-phenylchromone structure with antioxidant, free radical scavenging, cardiovascular, and trace estrogen-like effects. OBJECTIVE Screening and isolation of neuraminidase, lipoxidase, and lactate dehydrogenase inhibitors from M. sativa via ultrafiltration-liquid chromatography-mass spectrometry (UF-LC-MS) combined with stepwise flow rate counter-current chromatography (CCC). METHOD Utilising the medicinal plants M. sativa as the research objects and UF-LC-MS was used for activity screening followed by isolation and purification of the inhibitors by stepwise flow rate CCC. Finally, identification of the three active compounds was achieved by MS and nuclear magnetic resonance. RESULTS Three major compounds, viz. quercetin, genistein, and formononetin, were identified as potent neuraminidase, lipoxidase, and lactate dehydrogenase inhibitors, respectively. A two-phase solvent system of ethyl acetate/methanol/n-butanol/water (5.0:1.5:5.0:10; v/v/v/v) was subsequently selected for separation by stepwise flow rate CCC. CONCLUSION This novel approach based on UF-LC-MS and stepwise flow rate CCC represents a powerful tool for the screening and isolation of neuraminidase, lipoxidase, and lactate dehydrogenase inhibitors from complex matrices. Therefore, a useful platform for the large-scale production of bioactive and nutraceutical ingredients was developed herein.

Abstract
Background Trimethylamine-N-oxide (TMAO) is an independent risk factor for atherosclerosis. Consumption of hawthorn fruit is believed to be cardio-protective, yet whether it is able to suppress the TMAO-induced atherosclerosis remains unexplored. The present study was to investigate the effects of hawthorn fruit extract (HFE) on TMAO-exacerbated atherogenesis.
Methods Five groups of male Apolipoprotein E knock-out (ApoE−/−) mice were fed a low-fat diet (LFD), a Western high-fat diet (WD), or one of the three WDs containing 0.2% TMAO (WD + TMAO), 0.2% TMAO plus 1% HFE (WD + TMAO + L-HFE), or 0.2% TMAO plus 2% HFE (WD + TMAO + H-HFE), respectively. After 12-weeks of intervention, plasma levels of TMAO, lipid profile, inflammatory biomarkers, and antioxidant enzyme activities were measured. Atherosclerotic lesions in the thoracic aorta and aortic sinus were evaluated. The sterols and fatty acids in the liver and feces were extracted and measured. Hepatic expressions of inflammatory biomarkers and antioxidant enzymes were analyzed. Results Dietary TMAO accelerated atherogenesis, exacerbated inflammation, and reduced antioxidant capacities in the plasma and the liver. TMAO promoted hepatic cholesterol accumulation by inhibiting fecal excretion of acidic sterols. HFE could dose-dependently reduce the TMAO-aggravated atherosclerosis and inflammation. HFE was also able to reverse the TMAO-induced reduction in antioxidant capacity by up-regulating the expression of antioxidant enzymes including superoxide dismutase 1 (SOD1), SOD2, glutathione peroxidase 3 (GSH-Px3), and catalase (CAT) in the liver. Moreover, the hepatic cholesterol content was lowered by HFE via enhanced fecal excretion of neutral and acidic sterols. Conclusions The present results indicated that HFE was able to reduce the TMAO-exacerbated atherogenesis by attenuating inflammation and improving antioxidant capacity at least in mice.

Abstract
In the present study, we assessed the extraction of low molecular weight soluble polysaccharides (MESP) from soybean by-products using microwave-assisted enzymatic technology and proposed the chemical structure of MESP using Fourier transform-infrared spectroscopy, gas chromatography, and 1H and 13C nuclear magnetic resonance spectrum analysis. The results suggested that MESP mainly comprised arabinose, rhamnose, and glucuronic acid with (1→4) glycosidic linkages in the backbone. Compared with inulin, MESP was found to selectively stimulate the growth of Lactobacillus probiotics. Moreover, the results of in vitro fermentation indicated that MESP significantly increased the concentrations of both acetate and butyrate (p < 0.05). MESP were treated on lipopolysaccharide (LPS)-stimulated RAW264.7 cells to determine the anti-inflammatory effect in vitro. It was observed that MESP inhibited nitric oxide, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-10 production. Furthermore, Western blotting results indicated that MESP significantly attenuated LPS-induced downregulation of phosphorylation levels of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) in macrophages. The underlying mechanism might involve inhibition of the expression of pro-inflammatory cytokines, presumably via JAK2/STAT3 pathway. Collectively, the results of our study paved way for the production of MESP, which may be potentially used as nutraceutical ingredients for prebiotics and anti-inflammatory agents, from soybean residue.

Abstract
Shepherd's purse as a wild vegetable is getting more and more attention on health benefits. Water extract of shepherd's purse (WESP) was prepared and analyzed for the chemical constituents. The mice were fed high-fructose (HF) diet and treated with WESP at 50, 100 and 200 mg/kg·bw for 8 weeks. The HF-fed mice receiving WESP exhibited the inhibitions against abnormal weight gain, hepatic fat accumulation and lipid metabolic by down-regulating FAS and ACC expressions. WESP also significantly alleviated hyperglycemia, oxidative stress, and inflammatory response by regulating of NF-κB pathway. Moreover, WESP dose-dependently increased the acetic, propionic, and butyric acids levels in HF-fed mice. Furthermore, WESP significantly alleviated the HF-induced gut dysbiosis by reducing the ratio of Firmicutes to Bacteroidetes and increasing the abundance of potential beneficial bacteria. Our findings indicate that WESP may be an effective dietary supplement for preventing the liver damage.

Abstract
The potential effects of Komagataeibacter hansenii CGMCC 3917 cells on alcohol-induced liver injury and their probable mechanisms were investigated. Male Kunming mice were orally administered with alcohol (10 mL per kg BW) alone or in combination with administration of K. hansenii CGMCC 3917 cells at 2 × 108 and 2 × 106 CFUs for 10 weeks. Administration of strain CGMCC 3917 cells, especially high dose administration, decreased the liver weights, fat gain, and fatty-acid metabolism-related enzyme SCD-1, ACC and FAS expressions and endotoxin release, which were elevated by alcohol treatment. Furthermore, the total contents of long chain fatty acids of the liver and serum in alcohol-treated mice supplemented with a high dose of strain CGMCC 3917 cells were decreased to 5.44 ± 0.19 μg mL-1 and 3.66 ± 0.15 μg mL-1 from 6.65 ± 0.31 μg mL-1 and 4.52 ± 0.21 μg mL-1, respectively. Conversely, the SCFAs decreased by ethanol treatment, particularly the acetic acid, propionic acid and butyric acid, were obviously enhanced in the faeces, colon and cecum of the mice supplemented with strain CGMCC 3917 cells. Moreover, strain CGMCC 3917 cells could regulate gut microbiome by significantly decreasing the abundance of Actinobacteria, Proteobacteria and Firmicutes, and dramatically increasing the abundance of Bacteroidetes in alcohol-treated mice. These findings suggest that K. hansenii CGMCC 3917 cells alleviate alcohol-induced liver damage via regulating fatty acid metabolism and intestinal microbiota diversity in mice.

Abstract
Many natural polysaccharides from bio-resources hold advantages of multi-functions, high efficiency, non-toxicity or low side effect, and have strong potentials in protection against alcoholic liver damages. This review summarized the bio-resources, chemical and structural characteristics of natural polysaccharides with potentials in inhibition against alcoholic liver damages, and also emphasized knowledge on correlations between their chemical structure and function. Approximately 95 species were confirmed in generation of hepatoprotective polysaccharides. Products as crude polysaccharides originated from 17 species were sum up despite the indetermination of their accurate structure. Additional four polysaccharides were described for their known chemical structures. Possible roles of hepatoprotective polysaccharides were provided with evidence on antioxidant promotion, lipids regulation, apoptosis inhibition and anti-inflammation, as well as confirmations in immune enhancement, iron removal and anti-fibrosis when currently treated against the alcoholic liver damages. To sum up, this overview could serve to guide development and utilization of natural hepatoprotective polysaccharides.

Abstract
This study aimed to explore a novel strategy for the simultaneous consumption of soluble soybean polysaccharides (SSPS) and insoluble genistein to improve the bioavailability of genistein and its prevention against obesity and metabolic syndrome in high-fat diet (HFD)-induced obese mice. C57BL/6J mice were fed a normal diet and HFD supplemented or not (n = 8) with SSPS (2.5%), genistein (0.5%) and their mixture (S + G) for 12 weeks. The UPLC-qTOP/MS assay showed that SSPS observably enhanced the urinary concentration of genistein and its metabolites compared to that of single genistein in mice. Supplementation of SSPS, genistein or their combination prevented HFD-induced gain weight, dyslipidemia, oxidative stress and inflammation in obese mice. Interestingly, the combined S + G ingestion exhibited more effective alleviation of dyslipidemia by modulating hepatic FAS, ACC, SREBP-1C and ADRP expressions relative to that of individual SSPS or genistein. Furthermore, S + G activated the energy metabolism pathway AMPK in the liver, and the hepatic PPAR-α/PPAR-γ pathways were doubly activated to alleviate lipogenesis, inflammation, obesity and metabolic syndrome. Moreover, S + G supplementation dramatically modified the gut microbial species at the phylum level with a decrease in Firmicutes and increase in Bacteroidetes. These findings support that the combined supplementation of SSPS and genistein is a novel couple to prevent obesity and metabolic syndrome.

Abstract
AbstractWhile strong evidence from clinical studies suggests beneficial effects of carnitine supplementation on metabolic health, serious safety concerns associated with carnitine supplementation have been raised from studies in mice. Considering that the carnitine doses in these mice studies were up to 100 times higher than those used in clinical studies, the present study aimed to address possible safety concerns associated with long-term supplementation of a carnitine dose used in clinical trials. Two groups of NMRI mice were fed either a control or a carnitine-supplemented diet (1 g/kg diet) from weaning to 19 months of age, and parameters of hepatic lipid metabolism and stress signalling and skeletal muscle gene expression were analysed in the mice at 19 months of age. Concentrations of free carnitine and acetylcarnitine in plasma and tissues were higher in the carnitine than in the control group (P<0·05). Plasma concentrations of free carnitine and acetylcarnitine were higher in mice at adult age (10 and 15 months) than at advanced age (19 months) (P<0·05). Hepatic mRNA and protein levels of genes involved in lipid metabolism and stress signalling and hepatic and plasma lipid concentrations did not differ between the carnitine and the control group. Skeletal muscle transcriptome analysis in 19-month-old mice revealed only a moderate regulation between carnitine and control group. Lifelong carnitine supplementation prevents an age-dependent impairment of plasma carnitine status, but safety concerns associated with long-term supplementation of carnitine at doses used in clinical trials can be considered as unfounded.
