In this study,a novel polysaccharide GPA-G 2-H was derived from ginseng.Furthermore,the coherent study of its structural characteristics,fermented characteristics in vitro,as well as antioxidant mechanism of fermented product FGPA-G 2-H on Aβ25-35-induced PC 12 cells were explored.The structure of GPA-G 2-H was determined by means of zeta potential analysis,FTIR,HPLC,XRD,GC-MS and NMR.The backbone of GPA-G 2-H was mainly composed of→4)-α-D-Glcp-(1→with branches substituted at O-3.Notably,GPA-G 2-H was degraded by intestinal microbiota in vitro with total sugar content and pH value decreasing,and short-chain fatty acids(SCFAs)increasing.Moreover,GPA-G 2-H significantly promoted the proliferation of Lactobacillus,Muribaculaceae and Weissella,thereby making positive alterations in intestinal microbiota composition.Additionally,FGPA-G 2-H activated the Nrf 2/HO-1 signaling pathway,enhanced HO-1,NQO 1,SOD and GSH-Px,while inhabited Keap 1,MDA and LDH,which alleviated Aβ-induced oxidative stress in PC 12 cells.These provide a solid theoretical basis for the further development of ginseng polysaccharides as functional food and antioxidant drugs. 展开更多

Metabolomics covers a wide range of applications in life sciences,biomedicine,and phytology.Data acquisition(to achieve high coverage and efficiency)and analysis(to pursue good classification)are two key segments involved in metabolomics workflows.Various chemometric approaches utilizing either pattern recognition or machine learning have been employed to separate different groups.However,insufficient feature extraction,inappropriate feature selection,overfitting,or underfitting lead to an insufficient capacity to discriminate plants that are often easily confused.Using two ginseng varieties,namely Panax japonicus(PJ)and Panax japonicus var.major(PJvm),containing the similar ginsenosides,we integrated pseudo-targeted metabolomics and deep neural network(DNN)modeling to achieve accurate species differentiation.A pseudo-targeted metabolomics approach was optimized through data acquisition mode,ion pairs generation,comparison between multiple reaction monitoring(MRM)and scheduled MRM(sMRM),and chromatographic elution gradient.In total,1980 ion pairs were monitored within 23 min,allowing for the most comprehensive ginseng metabolome analysis.The established DNN model demonstrated excellent classification performance(in terms of accuracy,precision,recall,F1 score,area under the curve,and receiver operating characteristic(ROC))using the entire metabolome data and feature-selection dataset,exhibiting superior advantages over random forest(RF),support vector machine(SVM),extreme gradient boosting(XGBoost),and multilayer perceptron(MLP).Moreover,DNNs were advantageous for automated feature learning,nonlinear modeling,adaptability,and generalization.This study confirmed practicality of the established strategy for efficient metabolomics data analysis and reliable classification performance even when using small-volume samples.This established approach holds promise for plant metabolomics and is not limited to ginseng. 展开更多

Objective:To assess the protective effects of Panax ginseng(PG)against copper sulfate(CuSO_(4))-induced kidney toxicity in rats.Methods:The rats were randomly allocated into four groups:control,CuSO_(4),PG,and PG+CuSO_(4).The experiment continued for 14 days,during which CuSO_(4) was provided at a dosage of 100 mg/kg body weight per day and PG at 300 mg/kg body weight by oral gavage per day.Upon completion of the experiment,kidney sections were used for histological and histomorphometric analyses.The histochemical method was applied to ascertain the density of the glomerular mesangial matrix.The expressions of vascular endothelial growth factor(VEGF)and caspase-3 were examined using immunohistochemistry.The levels of malondialdehyde and glutathione,along with the activity of superoxide dismutase and catalase in the kidney,were measured.Results:PG treatment exhibited a marked protective effect against CuSO_(4)-induced renal damage,as evidenced by improved histopathological lesions,significantly reduced glomerular mesangial matrix density,VEGF in distal tubules,caspase-3 expression,and malondialdehyde levels in renal tissue,as well as enhanced superoxide dismutase and catalase activities.Conclusions:PG treatment ameliorates CuSO_(4)-induced kidney injury in rats.Further studies are warranted to verify its efficacy and elucidate the underlying mechanism of its nephroprotective action. 展开更多

BACKGROUND Ulcerative colitis(UC),a chronic and challenging condition,necessitates the development of more effective treatments owing to the unsatisfactory efficacy and side effects associated with current medications.Traditional Chinese medicine(TCM),known for its multi-stage and multi-targeted approach,has a long history in treating gastrointestinal diseases and offering a promising alternative UC treatment.Panax ginseng(P.ginseng),a commonly used remedy for UC in TCM,exemplifies this potential,although the specific components and mechanisms through which its therapeutic effects are exerted remain to be fully elucidated,highlighting the need for further research to unlock its full potential as a treatment option.AIM To investigate the key constituents and biological pathways through which P.ginseng exerts therapeutic effects on UC.METHODS Network pharmacology investigated the UC-alleviating mechanism of P.ginseng,including“active ingredient-target-disease”network analysis,and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses.Panaxadiol(PD;active ingredient of P.ginseng)was tested in a mouse model of 3%dextran sulfate sodium-induced UC,with assessments of body weight,Disease Activity Index scores,and colon length.Colitis and intestinal barrier integrity were analyzed via hematoxylin-eosin and Alcian blue and periodic acid-Schiff staining,immunohistochemistry,real time-quantitative PCR,and western blotting.RESULTS By integrating and analyzing the targets of P.ginseng and UC,15 critical hub genes were discovered.Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed the mechanisms involved to be linked to MAPK and PI3K-Akt signaling.Among the 10 main active ingredients identified as potentially effective,PD was most abundant and was validated in vivo to mitigate weight loss,reduce Disease Activity Index scores,and prevent colon shortening.PD also reduced inflammation and suppressed expression of pro-inflammatory cytokines and mediators.In addition,PD increased expression of mucin and tight junction proteins.Ultimately,PD counteracted effects of dextran sulfate sodium by inhibiting phosphorylation of NF-кB and MAPK,while increasing phosphorylation of AMPK and expression of NRF2 and NQO1.CONCLUSION PD alleviates colitis and aids intestinal barrier repair,partly via modulation of the MAPK/NF-кB and AMPK/NRF2/NQO1 pathways.These findings also suggest new research methods for treatment of UC with TCM. 展开更多

[Objectives]Farmland ginseng cultivation,as a sustainable alternative to traditional forest-clearing ginseng planting,requires systematic evaluation of soil optimization strategies.This study aimed to quantify the linkage between soil improvement outcomes and ginseng(Panax ginseng)yield across five regions in Yanbian Korean Autonomous Prefecture.[Methods]Soil improvement trials were conducted using farmland soils,with forest soils as the baseline.Soil nutrient contents were measured via soil agrochemical analysis method using a continuous flow analyzer.Statistical approaches,including significance tests,correlation analysis,and regression analysis,were applied to identify key factors influencing yield.[Results]Ginseng yield exhibited a significant positive correlation with organic matter content and available phosphorus,but a negative correlation with electrical conductivity,ammonium nitrogen,and available potassium.Wangqing and Liucai regions achieved post-improvement yields equivalent to 94%and 88%of forest soil yields,respectively,demonstrating the highest soil similarity to forest ecosystems.[Conclusions]Region-specific soil improvement protocols in Wangqing and Liucai show high replicability and efficacy.These strategies can serve as benchmarks for sustainable farmland ginseng cultivation,minimizing ecological disruption while maintaining productivity. 展开更多

Coptis chinensis Franch.and Panax ginseng C.A.Mey.are traditional herbal medicines with millennia of documented use and broad therapeutic applications,including anti-diabetic properties.However,the synergistic effect of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng on type 2 diabetes mellitus(T2DM)and its underlying mechanism remain unclear.The research demonstrated that the optimal ratio of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng was 4∶1,exhibiting maximal efficacy in improving insulin resistance and gluconeogenesis in primary mouse hepatocytes.This combination demonstrated significant synergistic effects in improving glucose tolerance,reducing fasting blood glucose(FBG),the weight ratio of epididymal white adipose tissue(eWAT),and the homeostasis model assessment of insulin resistance(HOMA-IR)in leptin receptor-deficient(db/db)mice.Subsequently,a T2DM liver-specific network was constructed based on RNA sequencing(RNA-seq)experiments and public databases by integrating transcriptional properties of disease-associated proteins and protein-protein interactions(PPIs).The network recovery index(NRI)score of the combined treatment group with a 4∶1 ratio exceeded that of groups treated with individual components.The research identified that activated adenosine 5'-monophosphate-activated protein kinase(AMPK)/acetyl-CoA carboxylase(ACC)signaling in the liver played a crucial role in the synergistic treatment of T2DM,as verified by western blot experiment in db/db mice.These findings demonstrate that the 4∶1 combination of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng significantly improves insulin resistance and glucose and lipid metabolism disorders in db/db mice,surpassing the efficacy of individual treatments.The synergistic mechanism correlates with enhanced AMPK/ACC signaling pathway activity. 展开更多

NAD(P)H oxidases were detected in suspension cultured cells of ginseng (Panax ginseng C. A. Meyer). The activities of these enzymes were induced by an elicitor (Cle) extracted from cell walls of Col-letotrichum lagerarium. In addition, Cle induced an oxidative burst and enhanced the synthesis of saponin, activity of phenylalanine ammonialyase (PAL) , accumulation of chalcone synthase (CHS) and the transcription of a hydroxyproline-rich glycoprotein gene ( hrgp ) . Pre-treatments with DPI and quinacrine (two inhibitors of mammalian neutrophil plasma membrane NADPH oxidase) for 30 min prior to Cle addition blocked the NAD(P)H oxidase activity induced by Cle. These inhibitors also inhibited the release of H2C2, the synthesis of saponin, PAL activity and CHS accumulation. Our data revealed homology between plasma membrane NAD(P)H oxidases of mammalian neutrophil cells and ginseng suspension cells. They also indicated that deactivated NAD(P)H oxidases catalysed the release of H2O2 and that H2O2 was functioning as a second messenger stimulating PAL activity, saponin synthesis and hrgp transcription. Elevations of Ca2 + and protein phos-phorylation/dephosphorylation were required for this defense process. We propose that NAD(P)H oxidases mediate the processes of Cle-induced defense responses in ginseng suspensions, and postulate the existence of a signalling cascade including extracellular Cle stimulation, activation of plasma membrane NAD(P)H oxidases, release of H2O2, and the intracellular responses of metabolism and gene transcription in ginseng suspension cells. 展开更多

Meyer) cells via cellulase degradation. CDW activated the NADPH oxidase activity of isolated plasma membranes and stimulated in vivo H2O2 generation in ginseng cell suspensions. CDW also increased the activity of phenylalanine ammonia lyase (PAL), expression of a P. ginseng squalene epoxidase (sqe) gene and saponin synthesis. NADPH oxidase inhibitors inhibited both in vitro NADPH oxidase activity and in vivo H2O2 generation. Induction of PAL activity, saponin synthesis and sqe gene expression were all inhibited by such inhibitor treatments and reduced by incubation with catalase and HA scavengers. These data indicate that activation of NADPH oxidase and generation of H2O2 are essential signalling events mediating defence responses induced by the endogenous elicitor(s) present in CDW. 展开更多

完成形态后熟和生理后熟期中的人参(PanaxyinsenyC.A.Mey)湿润种子的含水量由47%降至9.4%和5.8%,形成于籽后保存于室温,0~5℃和-196℃条件下1~3年。保存后的形态后熟于籽再低温处理,继续完成生理后熟。结果显示:完成形... 完成形态后熟和生理后熟期中的人参(PanaxyinsenyC.A.Mey)湿润种子的含水量由47%降至9.4%和5.8%,形成于籽后保存于室温,0~5℃和-196℃条件下1~3年。保存后的形态后熟于籽再低温处理,继续完成生理后熟。结果显示:完成形态后熟的种子在1~5℃保存1年后,种子胚根能萌发,但胚轴、胚芽不能正常生长,保存3年,种子丧失生活力;生理后熟期中的种子在0~5℃保存1年尚能正常出苗,出苗率为44.0%,保存3年,种胚已不能正常发育。但是在-196℃保存3年后,出苗率同保存在0~5C1年的相近.仍为43.1%。说明完成形态后熟种子还没有产生足够的脱水耐性,而经低温层积处理于生理后熟期中的种子就具有了这种耐性,并能进行低温短期或超低温长期保存。 展开更多
