According to TCM theory, SF can invigorate Qi in the liver and other visceral organs through the meridian system. Furthermore, the liver’s pivotal role in regulating the functions of various visceral organs helps explain how SF can promote holistic health benefits. The main active ingredient of SF, schisandrin B (Sch B), has been found to improve mitochondrial ATP production and enhance glutathione redox status in multiple organs. This could account for the overall protective effects of Sch B on organs. Due to its stronger impact on liver function, the positive influence of Sch B on different organs may be facilitated by signal molecules originating from the liver.展开更多

Once the model was established(after approximately 12 wk),rats were administered mosapride(1.54 mg/kg) or various doses of aqueous FAI extracts(1-4 g/kg) for 14 d. Transit function was assessed using an ink propulsion test. Rats were then sacrificed,and the ultramicrostructure of colonic tissue was examined using transmission electron microscopy. The expression of the 5-hydroxytryptamine receptor 4(5-HTR4) and neurofilament-H was assessed in colon tissues using real-time PCR,Western blot,and immunohistochemistry.RESULTS: Mosapride and high dose(4 g/kg) of aqueous FAI extracts significantly improved the bowel movement in cathartic colons compared to untreated model colons as measured by the intestinal transit rate(70.06 ± 7.25 and 72.02 ± 8.74,respectively,vs 64.12 ± 5.19; P < 0.05 for both). Compared to controls,the ultramicrostructure of cathartic colons showed signsof neural degeneration. Treatment with mosapride and aqueous FAI extracts resulted in recovery of ultrastructural pathology. Treatment with mosapride alone upregulated the gene and protein expression of 5-HTR4 compared to untreated controls(P < 0.05 for both). Treatment with aqueous FAI extracts(≥ 2 g/kg) increased 5-HTR4 m RNA levels(P < 0.05),but no change in protein level was observed by Western blot or immunohistochemistry. The m RNA and protein levels of neurofilament-H were significantly increased with mosapride and ≥ 2 g/kg aqueous FAI extracts compared to controls(P < 0.05 for all).CONCLUSION: Aqueous FAI extracts and mosapride strengthen bowel movement in cathartic colons via increasing the expression of 5-HTR4 and neurofilament-H.展开更多

Methods The key extraction parameters that influenced the yield of flavonid from Fructus Gardeniae were optimized by employing an orthogonal experiment [L9（3）4], including the ratio of buffer solution （Na2B4O7· 10H2O） to raw material, concentration of Fructus Gardeniae in extracting solution, extraction time and pH of buffer solution. An UV/Vis detector was used to perform the qualitative and quantitative analyses of the extracted flavonid with the using of the standard sample. Results The maximum extraction yield of the crude extract was 5.0533 （mg/g） after 20 min when the mass ratio of Na2B4O7 · 10H2O to raw material was 0.4%, the concentration of Fructus Gardeniae in the extraction solution was 1/12 （g/mL）, and pH of buffer solution was 4.5. The positive reactions to the Molish and HCI-Mg tests suggested that the extracted compound was flavonoid, and FTIR measurements also identified the presence of flavonoid in the extracts. Conclusion This work is expected to provide a basis for further research, development, and utilization of Fructus gardenia in flavonid extraction.展开更多

The purpose of this study is to evaluate and characterize the PL inhibition activities of the major constituents from Fructus Psoraleae(FP), one of the most frequently used Chinese herbs with lipid-lowering activity. To this end, a total of eleven major constituents isolated from Fructus Psoraleae have been obtained and their inhibition potentials against PL have been assayed by a fluorescence-based assay. Among all tested compounds, isobavachalcone, bavachalcone and corylifol A displayed strong inhibition on PL(IC50 < 10 μmol·L-1). Inhibition kinetic analyses demonstrated that isobavachalcone, bavachalcone and corylifol A acted as mixed inhibitors against PL-mediated 4-methylumbelliferyl oleate(4-MUO) hydrolysis, with the Ki values of 1.61, 3.77 and 10.16μmol·L-1, respectively. Furthermore, docking simulations indicated that two chalcones(isobavachalcone and bavachalcone) could interact with the key residues located in the catalytic cavity of PL via hydrogen binding and hydrophobic interactions. Collectively, these finding provided solid evidence to support that Fructus Psoraleae contained bioactive compounds with lipid-lowering effects via targeting PL, and also suggested that the chalcones in Fructus Psoraleae could be used as ideal leading compounds to develop novel PL inhibitors.展开更多

Based on single factor studies, a three-variable, three-level Box-Behnken design （BBD） was used to monitor the effects of independent variables, including processing temperature and time, on the dependent variables. Response surfaces and contour plots of the contents of total lignans, chlorogenic acid, arctiin, and aretigenin were obtained through ultraviolet and visible （UV-Vis） monitoring and high performance liquid chromatography （HPLC）. Fructus Arctii should be processed under heating in a pot at 311℃, medicine at 119℃ for 123s with flipping frequently. The experimental values under the optimized processing technology were consistent with the predicted values. In conclusion, RSM is an effective method to optimize the processing of traditional Chinese medicine （TCM）.展开更多

文摘Objective:To investigate the effects of Alpiniae oxyphyllae Fructus(AOF)on renal lipid deposition in diabetic kidney disease(DKD)and elucidate its molecular mechanisms.Methods:The mechanism of AOF in treating DKD was explored by network pharmacological enrichment analysis,molecular docking,and molecular dynamics simulation.The effects of AOF on renal function and lipid deposition were assessed in a mouse model of DKD and high glucose-stressed HK-2 cells.Cell viability and lipid accumulation were detected by CCK8 and oil red O staining.The expressions of PPARαand fatty acid oxidation-related genes(ACOX1 and CPT1A)were detected by quantitative RT-PCR,Western blot,and immunofluorescence.Furthermore,PPARαknockdown was performed to examine the molecular mechanism of AOF in treating DKD.Results:Network pharmacological enrichment analysis,molecular docking,and molecular dynamics simulation showed that the active compounds in AOF targeted PPARαand thus transcriptionally regulated ACOX1 and CPT1A.AOF lowered blood glucose,improved dyslipidemia,and attenuated renal injury in DKD mice.AOF-containing serum accentuated high glucose-induced decrease in cell viability and ameliorated lipid accumulation.Additionally,it significantly upregulated the expression of PPARα,ACOX1,and CPT1A in both in vivo and in vitro experiments,which was reversed by PPARαknockdown.Conclusions:AOF may promote fatty acid oxidation via PPARαto ameliorate renal lipid deposition in DKD.

文摘As one of the most common metabolic diseases,type 2 diabetes(T2D)has become a public health concern with rising global prevalence.Corni fructus(CF),a traditional Chinese herb utilized for centuries as homologous medicinal and food resources,has been widely used to treat glucose and lipid metabolism disorders.However,as a core active ingredient of CF,whether and how morroniside(MOR)improves T2D is still unclear.This study aimed to explore the pathways by which MOR ameliorates T2D in mice induced by high-fat diet(HFD)and low-dose streptozotocin through 16S rRNA gene sequencing.We found that MOR treatment significantly ameliorated body weight loss,hyperglycemia,hyperlipidemia and insulin resistance in T2D mice.In addition,MOR remarkably improved inflammation-and oxidative stress-driven hepatic and pancreatic injuries in the model mice.Mechanistically,MOR rehabilitated the dysregulated diversity and constitution of the gut microbiota in T2D mice,with significant changes in relative abundance in genus such as Lactobacillus,Lachnospiraceae_NK4A136_group,and Lachnospiraceae_UCG-006 which are believed to be highly correlated with serum parameters and insulin resistance in mice with T2D.Therefore,we infer that MOR improves T2D at least partially by maintaining the host microbiota homeostasis,and MOR may be a promising candidate for T2D treatment.

文摘Depression poses a considerable threat to global health,underscoring the critical need for safe treatments.Because of its homology of medicine and food,Gardeniae Fructus is widely used in clinical and everyday life contexts.Gardeniae Fructus oil(OGF)is a waste byproduct of the food industry with promising recycling potential.While previous research has demonstrated the antidepressant effects of OGF,the precise mechanism remains unclear.To fill this gap in the literature,this paper elucidates the composition and potential antidepressant mechanism of OGF.According to the results,OGF is mainly composed of fatty acids and unsaponifiable matter.OGF could effectively attenuate depression-like behaviors in mice with chronic unpredictable mild stress by modulating the microbiota-gut-brain axis.Mechanisms include improving gut dysbiosis,regulating short-chain fatty acids,protecting the intestinal barrier function,reducing hippocampal damage,and alleviating neuroinflammation by inhibiting the activation of the TLR4/NF-κB/NLRP3 pathway.Fecal microbiota transplantation experiments confirmed the involvement of the gut microbiota in the modulation of depression-like behavior by OGF.This study establishes the antidepressant effects of OGF as well as the underlying mechanism,demonstrating its potential as a novel dietary intervention for depression treatment.

文摘Schisandrae chinensis Fructus (SF) is a commonly used herb in Traditional Chinese Medicine (TCM). According to TCM theory, SF can invigorate Qi in the liver and other visceral organs through the meridian system. Furthermore, the liver’s pivotal role in regulating the functions of various visceral organs helps explain how SF can promote holistic health benefits. The main active ingredient of SF, schisandrin B (Sch B), has been found to improve mitochondrial ATP production and enhance glutathione redox status in multiple organs. This could account for the overall protective effects of Sch B on organs. Due to its stronger impact on liver function, the positive influence of Sch B on different organs may be facilitated by signal molecules originating from the liver.

文摘AIM: To examine the effect of aqueous fructus aurantii immaturus(FAI) extracts on the intestinal plexus of cathartic colons.METHODS: Cathartic colons were induced in rats with dahuang,a laxative used in traditional Chinese medicine. Once the model was established(after approximately 12 wk),rats were administered mosapride(1.54 mg/kg) or various doses of aqueous FAI extracts(1-4 g/kg) for 14 d. Transit function was assessed using an ink propulsion test. Rats were then sacrificed,and the ultramicrostructure of colonic tissue was examined using transmission electron microscopy. The expression of the 5-hydroxytryptamine receptor 4(5-HTR4) and neurofilament-H was assessed in colon tissues using real-time PCR,Western blot,and immunohistochemistry.RESULTS: Mosapride and high dose(4 g/kg) of aqueous FAI extracts significantly improved the bowel movement in cathartic colons compared to untreated model colons as measured by the intestinal transit rate(70.06 ± 7.25 and 72.02 ± 8.74,respectively,vs 64.12 ± 5.19; P < 0.05 for both). Compared to controls,the ultramicrostructure of cathartic colons showed signsof neural degeneration. Treatment with mosapride and aqueous FAI extracts resulted in recovery of ultrastructural pathology. Treatment with mosapride alone upregulated the gene and protein expression of 5-HTR4 compared to untreated controls(P < 0.05 for both). Treatment with aqueous FAI extracts(≥ 2 g/kg) increased 5-HTR4 m RNA levels(P < 0.05),but no change in protein level was observed by Western blot or immunohistochemistry. The m RNA and protein levels of neurofilament-H were significantly increased with mosapride and ≥ 2 g/kg aqueous FAI extracts compared to controls(P < 0.05 for all).CONCLUSION: Aqueous FAI extracts and mosapride strengthen bowel movement in cathartic colons via increasing the expression of 5-HTR4 and neurofilament-H.

文摘Objective It is imperative to provide some consistent experimental results for the extraction of flavonid from Fructus Gardeniae. Methods The key extraction parameters that influenced the yield of flavonid from Fructus Gardeniae were optimized by employing an orthogonal experiment [L9（3）4], including the ratio of buffer solution （Na2B4O7· 10H2O） to raw material, concentration of Fructus Gardeniae in extracting solution, extraction time and pH of buffer solution. An UV/Vis detector was used to perform the qualitative and quantitative analyses of the extracted flavonid with the using of the standard sample. Results The maximum extraction yield of the crude extract was 5.0533 （mg/g） after 20 min when the mass ratio of Na2B4O7 · 10H2O to raw material was 0.4%, the concentration of Fructus Gardeniae in the extraction solution was 1/12 （g/mL）, and pH of buffer solution was 4.5. The positive reactions to the Molish and HCI-Mg tests suggested that the extracted compound was flavonoid, and FTIR measurements also identified the presence of flavonoid in the extracts. Conclusion This work is expected to provide a basis for further research, development, and utilization of Fructus gardenia in flavonid extraction.

文摘Fructus Psoraleae,which is commonly consumed for the treatment of osteoporosis,bone fracture,and leucoderma,induces liver injury.This study investigated the pathogenesis of the ethanol extract of Fructus Psoraleae(EEFP)-induced liver injury in rats.EEFP(1.35,1.80,and 2.25 g·kg^–1)was administrated to Sprague Dawley(SD)rats for 30 d.We measured liver chemistries,histopathology,and quantitative isobaric tags for relative and absolute quantitation(iTRAQ)-based protein profiling.EEFP demonstrated parameters suggestive of liver injury with changes in bile secretion,bile flow rate,and liver histopathology.iTRAQ analysis showed that a total of 4042 proteins were expressed in liver tissues of EEFP-treated and untreated rats.Among these proteins,81 were upregulated and 32 were downregulated in the treatment group.KEGG pathway analysis showed that the drug metabolic pathways of cytochrome P450,glutathione metabolism,glycerolipid metabolism,and bile secretion were enriched with differentially expressed proteins.The expression of key proteins related to the farnesoid X receptor(FXR),i.e.,the peroxisome proliferators-activated receptor alpha(PPAR-α),were downregulated,and multidrug resistance-associated protein 3(MRP3)was upregulated in the EEFP-treated rats.Our results provide evidence that EEFP may induce hepatotoxicity through various pathways.Furthermore,our study demonstrates changes in protein regulation using iTRAQ quantitative proteomics analysis.

文摘Pancreatic lipase(PL), a crucial enzyme in the digestive system of mammals, has been proven as a therapeutic target to prevent and treat obesity. The purpose of this study is to evaluate and characterize the PL inhibition activities of the major constituents from Fructus Psoraleae(FP), one of the most frequently used Chinese herbs with lipid-lowering activity. To this end, a total of eleven major constituents isolated from Fructus Psoraleae have been obtained and their inhibition potentials against PL have been assayed by a fluorescence-based assay. Among all tested compounds, isobavachalcone, bavachalcone and corylifol A displayed strong inhibition on PL(IC50 < 10 μmol·L-1). Inhibition kinetic analyses demonstrated that isobavachalcone, bavachalcone and corylifol A acted as mixed inhibitors against PL-mediated 4-methylumbelliferyl oleate(4-MUO) hydrolysis, with the Ki values of 1.61, 3.77 and 10.16μmol·L-1, respectively. Furthermore, docking simulations indicated that two chalcones(isobavachalcone and bavachalcone) could interact with the key residues located in the catalytic cavity of PL via hydrogen binding and hydrophobic interactions. Collectively, these finding provided solid evidence to support that Fructus Psoraleae contained bioactive compounds with lipid-lowering effects via targeting PL, and also suggested that the chalcones in Fructus Psoraleae could be used as ideal leading compounds to develop novel PL inhibitors.
