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

Background As living standards improve,consumers are placing greater emphasis on the enhancement of fish flesh quality,making its improvement increasingly critical.Plant-derived polysaccharides positively affect the improvement of animal flesh quality.Panax ginseng leaf polysaccharides(PGLP)have a similar composition and lower cost compared with Panax ginseng root polysaccharides.However,its function and application effects in grass carp(Ctenopharyngodon idella)are unclear.Methods A total of 540 sub-adult grass carp(679±1.29 g),one of the important economic fish species,were used as experimental models and fed diets supplemented with 0,100,200,300,400,or 500 mg/kg PGLP for 60 d.After 60 d,grass carp were weighed,and their muscles were collected to explore the effects of PGLP on the growth and development of myofibers and energy metabolism-related parameters.Results Our study found that PGLP increased the growth performance and muscle nutritional composition as well as improved muscle hardness,springiness,cohesiveness,chewiness,and hyperplasia of myofibers of sub-adult grass carp.Besides,PGLP promoted muscle energy metabolism by increasing creatine,glycogen,pyruvate,and acetyl-CoA contents and creatine kinase(CK),pyruvate kinase(PK),phosphofructokinase(PFK),and hexokinase(HK)activities,while decreasing lactate dehydrogenase(LDH)activity and lactate content in fish muscle.Finally,our study found that PGLP enhanced mitochondrial function by increasing the protein expression of mitochondrial complexes I–V,biogenesis,and fusion and decreasing autophagy and fission in fish muscle.Conclusions PGLP improved growth performance and flesh quality of sub-adult grass carp,which may be related to enhancing hyperplasia of myofibers by promoting energy metabolism.We concluded that the recommended amount of PGLP in sub-adult grass carp feed to optimize growth performance is 100–200 mg/kg.This study provides a theoretical basis for the application of PGLP in fish feed and for the analysis of the mechanism of nutrition and feed regulating fish flesh quality,which is of great significance. 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

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

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

The strains were identified through morphology, physiological and biochemical characteristics and 16S rDNA. [ Result ] With Rhizoctonia solani, Fusarium oxysporum and Fu- sarium solani as the indicator strains, two biocontrol strains B59 and X1 with strong antagonistic effects were screened from the rhizosphere soil of diseased ginseng in Tieli farm of Heilongjiang Province, and they were identified to be Bacillus subtilis. The inhibition rates of two biocontrol strains against eight different fungi were all greater than 90%. The primary study indicated that B59 and X1 strains could secrete antifungal active substances. [ Conclusion] Two biocontrol Bacillus subti- lis strains 1359 and X1 all had strong antagonistic effect against ginseng soil-borne disease, which had certain potential for development and utilization. 展开更多
