Comparison of Wild and Cultivated Codonopsis pilosula Based onTraditional Quality Evaluation / 中国实验方剂学杂志

ObjectiveTo conduct a systematic comparative study on wild and cultivated Codonopsis pilosula（CP） from three aspects， including characters， microscopy， and contents of primary and secondary metabolites. MethodWild and cultivated CP samples were collected， their characters were measured using vernier caliper， tape measure and balance， the paraffin sections were stained with safranin-fixed green dyeing， and their microstructure were observed under the optical microscope. The content of alcohol-soluble extracts in wild and cultivated CP was determined according to the method for determination of extract under CP in the 2020 edition of Chinese Pharmacopoeia， the starch content was determined by anthrone colorimetry， the content of total polysaccharides was determined by kit method， Fiber analyzer was used to determine the content of fiber components， and ultra performance liquid chromatography（UPLC） was used to determine the content of monosaccharides， disaccharides and some secondary metabolites. Multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were employed to screen key differential components between wild and cultivated CP on the basis of variable importance in the projection（VIP） value>1 and P<0.05. ResultIn terms of morphological characteristics， the "lion's head-like" shape， longitudinal wrinkles， and circumferential wrinkles below the root cap of wild CP were more pronounced in wild CP compared to the cultivated ones. Regarding transverse sectional features， wild CP had more fissures on the outer side of the cortex and a larger duramen. Under microscopic examination， wild CP had more stone cells， a larger proportion of xylem， and the presence of cork cells arranged in rings in the xylem， while cultivated CP has a larger proportion of phloem， smaller vessel diameters， and a more loosely arranged vascular system. In terms of primary metabolites， the contents of 45% ethanol-soluble extract and total polysaccharides in cultivated CP were significantly higher than those in the wild ones（P<0.05）， the contents of lignin， hemicellulose， cellulose， fructose and glucose in wild CP were significantly higher than those in the cultivated ones（P<0.05）， while sucrose content in the cultivated CP was significantly higher than that in the wild ones（P<0.05）. Concerning secondary metabolites， the contents of tryptophan and tangshenoside Ⅰ in cultivated CP were significantly higher than those in the wild ones（P<0.05）， whereas the contents of lobetyolinin， lobetyol and atractylenolide Ⅲ in wild CP were significantly higher than those in the cultivated ones（P<0.05）. ConclusionThere are significant differences between wild and cultivated CP in terms of morphological characteristics， microscopic features and chemical composition. Glucose， fructose， sucrose， tangshenoside Ⅰ， tryptophan and cellulose components are the key differential components between wild and cultivated CP. Wild CP contains more polyacetylenes and fructose， whereas cultivated CP has higher levels of tangshenoside Ⅰ and sucrose， with noticeably lower cellulose content. These distinctions may be related to their growth conditions， growth years and cultivation techniques. Based on the results of this study， it is recommended to increase polyacetylenes and the content ratio of fructose to sucrose as an indicators to characterize different production methods of CP， in order to guide the high-quality production of CP.

Effects of stereoscopic traction on photosynthetic characteristics, yield, and quality of Codonopsis pilosula under organic cultivation / 中国中药杂志

To solve the serious problem of stem and leaf shading in the middle and late stage of traditional flat planting of Codonopsis pilosula, this study analyzed the effects of different stereoscopic traction heights on the photosynthetic characteristics and growth of C. pilosula and explored the optimal traction height to improve the yield and quality of C. pilosula. The experiment designed three stereo-scopic traction heights [H1(60 cm), H2(90 cm), and H3(120 cm)] with natural growth without traction as the control(CK). The results showed that the increase in stereoscopic traction heights broadened the growth space of stems and leaves of C. pilosula, enhanced the ventilation effect, significantly increased the average daily net photosynthetic rate of C. pilosula, promoted the absorption of intercellular CO_2, decreased the transpiration rate, and reduced the evaporation of water. Moreover, it effectively avoided the problem of weakened photosynthesis, maintained the carbon balance of individual plants, and promoted the growth and development of the C. pilosula roots. In terms of the seed yield of C. pilosula, it was ranked as H2>H1>H3>CK. To be specific, H1 increased by 213.41% compared with CK, H2 increased by 282.43% compared with CK, and H3 increased by 133.95% compared with CK. The yield and quality of C. pilosula were the highest in the H3 treatment group, with the fresh yield of 6 858.33 kg·hm~(-2), 50.59% higher than CK, dry yield of 2 398.33 kg·hm~(-2), 76.54% higher than CK, and lobetyolin content of 0.56 mg·g~(-1), 45.22% higher than CK. Therefore, the stereoscopic traction height has a great influence on the photosynthetic characteristics, yield, and quality of C. pilosula. Particularly, the yield and quality of C. pilosula can be optimized and improved in the traction height treatment of H3(120 cm). This planting method is worth popularizing and applying in the cultivated management of C. pilosula.

Screening and expression analysis of transcription factors involved in genuineness of Codonopsis pilosula in Shanxi / 中国中药杂志

This study aims to mine the transcription factors that affect the genuineness of Codonopsis pilosula in Shanxi based on the transcriptome data of C. pilosula samples collected from Shanxi and Gansu, and then analyze the gene expression patterns, which will provide a theoretical basis for the molecular assisted breeding of C. pilosula. Gene ontology(GO) functional annotation, conserved motif prediction, and gene expression pattern analysis were performed for the differential transcription factors predicted based on the transcriptome data of C. pilosula from different habitats. A total of 61 differentially expressed genes(DEGs) were screened out from the transcriptome data. Most of the DEGs belonged to AP2/ERF-ERF family, with the conserved motif of [2X]-[LG]-[3X]-T-[3X]-[AARAYDRAA]-[3X]-[RG]-[2X]-A-[2X]-[NFP]. Forty-three of the DEGs showed significantly higher gene expression in C. pilosula samples from Shanxi than in the samples from Gansu, including 11 genes in the AP2/ERF-ERF family, 5 genes in the NAC fa-mily, 1 gene in the bHLH family, and 2 genes in the RWP-RK family, while 18 transcription factors showed higher expression levels in the samples from Gansu. GO annotation predicted that most of the DEGs were enriched in GO terms related to transcriptional binding activity(103), metabolic process(26), and stress response(23). The expression of transcription factor genes, CpNAC92, CpNAC100, CpbHLH128, and CpRAP2-7 was higher in the samples from Shanxi and in the roots of C. pilosula. CpNAC92, CpbHLH128, and CpRAP2-7 responded to the low temperature, temperature difference, and iron stresses, while CpNAC100 only responded to low temperature and iron stresses. The screening and expression analysis of the specific transcription factors CpNAC92, CpNAC100, CpbHLH128, and CpRAP2-7 in C. pilosula in Shanxi laid a theoretical foundation for further research on the mechanism of genuineness formation of C. pilosula.

Therapeutic potential of alkaloid extract from Codonopsis Radix in alleviating hepatic lipid accumulation: insights into mitochondrial energy metabolism and endoplasmic reticulum stress regulation in NAFLD mice / 中国天然药物

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.

Mechanism of action of Scutellaria barbata combined with Codonopsis pilosula in the treatment of Bladder carcinoma based on network pharmacology and experimental validation / 国际生物医学工程杂志

Objective:To investigate the mechanism of bladder cancer treatment by using Scutellaria barbata and Codonopsis pilosula drug pair through network pharmacology. Methods:The drug composition of the drug pair was screened using TCMSP, and their action targets were predicted using Swiss Target Prediction. GeneCards was used to obtain disease targets of bladder cancer, and venny 2.1 was used to obtain intersection targets. PPI analysis was performed using STRING, and a network diagram was constructed using Cytoscape. GO and KEGG analysis were conducted using Metascape. A drug-target-pathway network map was constructed using Cytoscape software. Nude mice were randomly divided into a model group and a treatment group to establish a bladder cancer mouse model. On the 8th day after model formation, the mice in the model group were administered intragastrically with a dose of 342.86 mg/kg, 0.2 ml, twice/day. On the 28th day after modeling, the tumor size of nude mice was measured. Prostaglandin G/H Synthetase 2 (PTGS2), PTGS1, Nuclear Receptor Coactivator 2 (NCOA2), Retinoic Acid X Receptor α (RXRA), Progesterone Receptor (PGR), Mitogen-Activated Protein Kinase 1 (MAPK1), Reticuloendothelial Proliferation virus oncogene homology A (RELA), and Akt1 levels were detected by enzyme-linked immunosorbent assay.Results:The results show that 45 active components of the drug pair directly acted on 187 disease targets through multiple pathways to treat bladder cancer, in which Quercetin, luteolin, wogonin, 7-Methoxy-2-methyl isoflavone, baicalein, beta-sitosterol, Stigmastero, and other core ingredients, as well as PTGS2, PTGS1, NCOA2, RXRA, PGR, MAPK1, RELA, and Akt1 are critical targets. The results of gene function annotation analysis show that the biological processes most likely related to crossover genes mainly involved responses to hormones, cell responses to lipids, responses to foreign stimuli, and responses to bacterial molecules. The cell components mainly involves transcription regulatory complexes, membrane rafts, membrane microregions, and RNA polymerase Ⅱ transcriptional regulatory complexes, etc. The molecular functions mainly involve transcription factor binding, DNA-binding transcription factor binding, RNA polymerase Ⅱ specific DNA-binding transcription factor binding, nuclear receptor activity, ligand-activated transcription factor activity, etc. The results of pathway enrichment analysis suggests that the main signaling pathways are AGE-RAGE, IL-17, PI3K-Akt, TNF, MAPK, HIF-1, apoptosis, p53, toll-like receptor, etc. Animal experiments show that the Scutellaria barbata and Codonopsis pilosula drug pair can significantly improve tumor size and also improve the expression levels of PTGS2, PTGS1, NCOA2, RXRA, PGR, MAPK1, RELA, and Akt1. Conclusions:The Scutellaria barbata and Codonopsis pilosula drug pair can regulate PTGS2, PTGS1, NCOA2, RXRA, PGR, MAPK1, RELA, and Akt1 and other diseases mainly through the regulation of AGE-RAGE, IL-17, PI3K-Akt, TNF, MAPK, HIF-1, apoptosis, p53, toll-like receptor, and other signaling pathways. Targeting enzyme activity and cell apoptosis can treat bladder cancer by regulating these biological processes.

Identification and analysis of glycosyltransferase in Codonopsis pilosula from different regions based on transcriptome / 药学学报

Lu Dangshen is the geoherb in Shanxi Province. The content of Codonopsis pilosula polysaccharides (CPP) in Lu Dangshen is more than that in other Codonopsis Radix from other regions. Glycosyltransferase is the key enzyme for the synthesis of bioactive components, such as CPP and tangshenoside I. Based on the transcriptome data of C. pilosula [Codonopsis pilosula (Franch.) Nannf.] from different producing areas, this study carried out functional annotation of GO and KEGG, conservative domain analysis, phylogenetic tree analysis and expression pattern analysis of glycosyltransferase genes in C. pilosula to provides a theoretical basis for exploring the mechanism of genuineness formation in Lu Dangshen. In this study, 98 glycosyltransferase genes were screened and identified, which belonged to GT family 1, GT family 2, GT family 90 and other families. By GO functional annotation, it was found that most of the glycosyltransferase genes had catalytic activity. Analysis of KEGG functional annotation showed that C. pilosula glycosyltransferase was mainly involved in glycan organism and terpenoid and polyketone metabolism. Among them, conserved domain of 42 glycosyltransferase genes in GT family 1 was [X]-W-[2X]-Q-[3X]-[LH]-[5X]-[FLTHCGWNS]-[2X]-E-[4X]-[GVP]-[4X]-P-[4X]-Q-[2X]-[NAK]. Phylogenetic tree analysis based on the glycosyltransferase sequence in Arabidopsis thaliana showed that C. pilosula glycosyltransferases were mainly located in Arabidopsis thaliana UGT73, 72 and 85 branches. Gene expression pattern analysis showed that expression of CpUGT73AH2 was higher in Lu Dangshen than that in Baitiaodang and could respond to drought and low temperature stress. In conclusion, a glycosyltransferase gene CpUGT73AH2, which is involved in the metabolism of terpenoids and polyketides and can respond to environmental stress, was screened from the C. pilosula glycosyltransferase family 1, which was used to further study the role of C. pilosula glycosyltransferase in Lu Dangshen. It laid a theoretical foundation for further study on the role of C. pilosula glycosyltransferase in the formation of Lu Dangshen.

Network pharmacology unveils spleen-fortifying effect of Codonopsis Radix on different gastric diseases based on theory of “same treatment for different diseases” in traditional Chinese medicine / 中草药·英文版

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.

Effects of Codonopsis tralictrifolia Extract on Collagen-induced Arthritis Model Rats and Its Mechanism Study / 中国药房

OBJECTIVE：To study the effec ts of Tibetan Codonopsis tralictrifolia extract （called“ZDS”for short ） on collagen-induced arthritis （CIA）model rats and its mechanism. METHODS ：Eight of 48 rats were randomly selected as normal control group （normal saline ），and the remaining 40 rats were used to establish CIA model. After successful modeling ，the rats were randomly divided into model group （normal saline ），ZDS low-dose ，medium-dose and high-dose groups （0.44，0.88，1.76 g/kg，by crude drug ），dexamethasone group （positive control ，0.002 5 g/kg），with 8 rats in each group. They were given relevant medicine intragastrically ，the volume of 400 μL，once a day ，for consecutive 28 days. The body weight of rats were weighed before medication （0 d），7，14，21 and 28 days after medication ；and arthritis indexes were scored. The pathological changes of the knee joint synoviual tissue were observed after last medication. The thymus index ，spleen index ，the levels of serum inflammatory factors （IL-1β，TNF-α，IL-6），protein expressions of NF-κB p65，p-NF-κB p65，IκB and p-IκB in synovial tissue were detected. RESULTS ：Compared with normal control group ，the body weight （14，21，28 days after administration ）of rats in model group was significantly reduced （P＜0.05）；the arthritis index score （before administration and different administration time）was significantly increased （P＜0.05）；the joint synovial tissue was pathologically damaged ；the thymus and spleen index ， inflammation factor level ，the protein expression of p-NF-κB p65 and p-IκB were increased significantly（P＜0.05），while the protein expression of IκB was decreased significantly（P＜0.05）. Compared with model group ，the level of IL- 1β was decreased significantly in ZDS low-dose group （P＜0.05）. Body weight of rats （21，28 days after administration ）were increased significantly in ZDS medium-dose and high-dose groups ，dexamethasone group （P＜0.05），while arthritis index score （14，21，28 days after administration ） was decreased significantly （P＜0.05）. The pathological damage of joint synovial tissue was significantly relieved ；thymus and spleen index ，inflammation factor level ，the protein expression of p-NF-κB p65 and p-IκB were significantly reduced，while the protein expression of IκB was significantly increased （P＜0.05）. CONCLUSIONS ：ZDS can improve CIA model rats to some extent ，and its mechanism may be related to the inhibition of NF-κB signaling pathway.

Study on the Tonifying Spleen Effect of Codonopsis pilosula Polysaccharides on Sennae Folium -induced Spleen- deficiency Model Mice / 中国药房

OBJECTIVE： To study the tonifying spl een effect of Codonopsis pilosula polysaccharides （CPP） on spleen-deficiency model mice. METHODS ：Totally 60 ICR male mice were randomized into blank group ，model group ，CPP high-dose，medium-dose and low-dose groups [ 1.6，0.8，0.4 g/（kg·d）]，Sijunzi tang （SJZT）group [ 30 g/（kg·d），by crude drug] ， with 10 mice in each group. Except for blank group ，other groups were given Sennae Folium solution intragastrically （0.4 g/d）to establish spleen-deficiency model. After modeling ，administration groups were given relevant drug intragastrically ，and blank group and model group were given 20 mL/kg normal saline intragastrically ，once a day ，for consecutive 6 weeks. After last administration，body weight of mice in each group was measured and their general behavioral characteristics were observed. The red blood cell count in whole blood were recorded ，and the contents of D-xylose，gastrin（GAS），motilin（MTL），somatostatin （SS），vasoactive intestinal peptide （VIP），amylase（AMS），immunoglobulin（IgG and IgM ）and lipopolysaccharide （LPS）in serum were determined ；mRNA and protein expressions of Claudin and Occludin in colon tissues of mice were also detected. RESULTS：Compared with blank group ，body weight of mice in model group was significantly decreased （P＜0.05），and the spleen deficiency symptoms such as sparse back hair and no luster appeared ；the red blood cell count in whole blood ，serum contents of D-xylose，SS，VIP，AMS，IgG and IgM ，mRNA and protein expressions of Claudin and Occludin were significantly decreased（P＜0.05 or P＜0.01）；serum contents of GAS ，MTL and LPS were significantly increased （P＜0.01）. Compared with model group ，the body weight of mice were increased significantly in CPP high-dose group （P＜0.05），and spleen-deficiency symptom was improved significantly. Except for the serum contents of D-xylose and IgM ，the protein expressions of Claudin and Occludin in colon tissue had no statistical significance in CPP low-dose group （P＞0.05），above indexes of other groups w ere improved significantly （P＜0.05 or P＜0.01）. CONCLUSION ：CPP can i mprove spleen-defic iency model mice induced by Sennae Folium，the mechanism of which may be associated with regulating gastrointestinal hormone secretion ， enhancing immunity and protecting intestinal mucosal barrier.
