Lobetyolin, polysaccharide, sucrose,glucose, and fructose were detected simultaneously in Codonopsis Radix samples treated with different processing methods including dryer-drying, sun-drying, shade-drying, sulfur fumigation, and kneading,etc.Results: The results showed that different processing methods had an obvious impact on the quality of Codonopsis Radix. Sun-drying or shade-drying was recommended, and sulfur fumigation should be avoided. And dryer-drying at 40 °C-50 °C was suggested to meet the requirement for large scale processing. In addition, based on the content of polysaccharide, glucose, and fructose, it was advised to knead for three times. As for lobetyolin and sucrose, kneading should be avoided.Conclusions: Our findings demonstrated that processing method had a big impact on the quality of Codonopsis Radix. Based on the results, the appropriate processing methods directed at different requirements were recommended. The study could lay a foundation for the reasonable processing of Codonopsis Radix in producing areas.展开更多

文摘Alkaloids are a class of naturally occurring bioactive compounds that are widely distributed in various food sources and Traditional Chinese Medicine.This study aimed to investigate the therapeutic effects and underlying mechanisms of alkaloid extract from Codonopsis Radix(ACR)in ameliorating hepatic lipid accumulation in a mouse model of non-alcoholic fatty liver disease(NAFLD)induced by a high-fat diet(HFD).The results revealed that ACR treatment effectively mitigated the abnormal weight gain and hepatic injury associated with HFD.Furthermore,ACR ameliorated the dysregulated lipid metabolism in NAFLD mice,as evidenced by reductions in serum triglyceride,total cholesterol,and low-density lipoprotein levels,accompanied by a concomitant increase in the high-density lipoprotein level.ACR treatment also demonstrated a profound anti-oxidative effect,effectively alleviating HFD-induced oxidative stress and promoting ATP production.These effects were achieved through the up-regulation of the activities of mitochondrial electron transfer chain complexes Ⅰ,Ⅱ,Ⅳ,and Ⅴ,in addition to the activation of the AMPK/PGC-1α pathway,suggesting that ACR exhibits therapeutic potential in alleviating the HFD-induced dysregulation of mitochondrial energy metabolism.Moreover,ACR administration mitigated HFD-induced endoplasmic reticulum(ER)stress and suppressed the overexpression of ubiquitin-specific protease 14(USP14)in NAFLD mice.In summary,the present study provides compelling evidence supporting the hepatoprotective role of ACR in alleviating lipid deposition in NAFLD by improving energy metabolism and reducing oxidative stress and ER stress.These findings warrant further investigation and merit the development of ACR as a potential therapeutic agent for NAFLD.

文摘Objective: To observe the effect of different processing methods on the quality of Codonopsis Radix and provide data reference for the reasonable processing in the producing areas.Methods: An analytical strategy that combined quantitative and HPLC fingerprint analysis with chemometrics was developed for the quality evaluation of Codonopsis Radix. Lobetyolin, polysaccharide, sucrose,glucose, and fructose were detected simultaneously in Codonopsis Radix samples treated with different processing methods including dryer-drying, sun-drying, shade-drying, sulfur fumigation, and kneading,etc.Results: The results showed that different processing methods had an obvious impact on the quality of Codonopsis Radix. Sun-drying or shade-drying was recommended, and sulfur fumigation should be avoided. And dryer-drying at 40 °C-50 °C was suggested to meet the requirement for large scale processing. In addition, based on the content of polysaccharide, glucose, and fructose, it was advised to knead for three times. As for lobetyolin and sucrose, kneading should be avoided.Conclusions: Our findings demonstrated that processing method had a big impact on the quality of Codonopsis Radix. Based on the results, the appropriate processing methods directed at different requirements were recommended. The study could lay a foundation for the reasonable processing of Codonopsis Radix in producing areas.

文摘Objective: "Same treatment for different diseases" is a unique treatment strategy under the guidance of traditional Chinese medicine(TCM) theory.Codonopsis Radix(Codonopsis pilosula,Dangshen in Chinese)with spleen-fortifying effect was employed to understand the strategy of "Same treatment for different diseases",based on its common mechanism in the treatment of gastric diseases including gastric ulcer,gastritis and gastric cancer via network pharmacology research.Methods:Network pharmacology research methods were used to analyze the interaction network and potential mechanisms of Dangshen in treating gastric ulcer,gastritis and gastric cancer.The active components and their target proteins of Dangshen were integrated from TCMSP,BATMAN-TCM databases.The targets of gastric ulcer,gastritis and gastric cancer were collected through GeneCards,PubMed,TDD and DisGeNET Database.Through screening,the key components and the key targets of Dangshen in treating gastric ulcer,gastritis and gastric cancer were obtained.After KEGG pathway analysis and GO analysis,the important pathways and biological processes were analyzed.Results:Through data and literature mining,the common and specific pharmaceutical effects and mechanism of Dangshen were summarized in these three gastric lesions.It was shown that Dangshen mainly acted on gastric ulcer,gastritis and gastric cancer through the overall regulation of the PI3K-AkT signaling pathway.With the development of the disease,it will gradually increase the control of inflammation through TNF,NF-κB and other inflammation-related signaling pathways to reduce inflammatory damage.For tumorigenesis,it pays more attention to inhibiting the ErbB signaling pathways to reduce the proliferation and migration of tumor cells.In addition,Dangshen's regulation of HIF-1 signaling pathway may also be beneficial for the treatment of gastric ulcer,gastritis and gastric cancer.Conclusion:Dangshen achieves spleen-fortifying effect on gastric diseases including gastric ulcer,gastritis and gastric cancer through multiple targets in multiple pathways,especially PI3K-AKT pathway and HIF-1 pathway.It could provide a scientific basis for understanding the strategy of "Same treatment for different diseases" in traditional Chinese medicine.

文摘Codonopsis pilosula(CP),a well-known food medicine homology plant,is commonly used in many countries.In our preliminary study,a series of pyrrolidine alkaloids with high MS responses were detected as characteristic absorbed constituents in rat plasma after oral administration of CP extract.However,their structures were unclear due to the presence of various isomers and the lack of reference standards.In the present study,an MS-guided targeted isolation of pyrrolidine alkaloids of CP extract was performed by ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry(UPLC/Q-TOF MS).For data analysis under fast data directed acquisition mode(Fast-DDA),an effective approach named characteristic fragmentation-assisted mass spectral networking was successfully applied to discover new pyrrolidine alkaloids with high MS response in CP extract.As a result,seven new pyrrolizidine alkaloids[codonopyrrolidiums C–I(3–9)],together with two known ones(1 and 2),were isolated and identified by NMR spectral analysis.Among them,codonopyrrolidium B(1),codonopyrrolidium D(4)and codonopyrrolidium E(5)were evaluated for lipid-lowering activity,and they could improve high fructose-induced lipid accumulation in HepG2 cells.In addition,the characteristic MS/MS fragmentation patterns of these pyrrolizidine alkaloids were investigated,and 17 pyrrolidine alkaloids were identified.This approach could accelerate novel natural products discovery and characterize a class of natural products with MS/MS fragmentation patterns from similar chemical scaffolds.The research also provides a chemical basis for revealing in vivo effective substances in CP.

文摘Background:Serratia ureilytica DW2 is a highly efficient phosphate-solubilizing bacteria isolated from Codonopsis pilosula rhizosphere soil that can promote the growth of C.pilosula;nonetheless,until now,no validated reference genes from the genus Serratia have been reported that can be used for the normalization of quantitative real-time polymerase chain reaction(RT–qPCR)data.Methods:To screen stable reference genes of S.ureilytica DW2,the expression of its eight candidate reference genes(16S rRNA,ftsZ,ftsA,mreB,recA,slyD,thiC,and zipA)under different treatment conditions(pH,temperature,culture time,and salt content)was assayed by RT–qPCR.The expression stability of these genes was analyzed using different algorithms(geNorm,NormFinder,and BestKeeper).To verify the reliability of the data,the expression of the glucose dehydrogenase(gdh)gene under different soluble phosphate levels was quantified using the most stably expressed reference gene.Results:The results showed that the zipA and 16S rRNA genes were the most stable reference genes,and the least stable genes were thiC and recA.The expression of gdh was consistent with the phosphate solubilization ability on plates containing the National Botanical Research Institute phosphate growth medium.Conclusion:Therefore,this study provides a stable and reliable reference gene of Serratia for the accurate quantification of functional gene expression in future studies.
