Objective:This study was designed to evaluate the hypolipidemic activity of Brassica rapa and explore its mechanism by network pharmacology approach.Methods:The hypolipidemic activity of Brassica rapa aqueous extract(BRAE)was evaluated by bile salt-binding capacity and oleic acid-induced HepG2 steatosis cell model.The active compounds of Brassica rapa were collected from literature,and targets were predicted from SwissTargetPrediction and SEA Search Server platform.Cytoscape 3.7.2 software was used to construct“compound-target”network.Protein-protein interaction(PPI)network was constructed by String platform.Gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)enrichment analyses based on DAVID database.Results:In vitro experiment showed that BRAE exhibited excellent bile salt-binding capacity,and the binding rates of sodium glycylcholate,sodium taurocholate and sodium deoxycholate were 36.01%,28.93%and 78.55%at 7 g.L-1,respectively.BRAE showed a significant hypolipidemic activity on steatosis cells,which can reduce the accumulation of lipid droplets and the levels of triglyceride(TG)and total cholesterol(TC)compared with the model group(P<0.05).21 active components of Brassica rapa and 682 potential targets were obtained,among which 55 targets were associated with hyperlipidemia.The“compound-target”network showed that 6-paradol,6-shogaol,benzyl-beta-D-glucopyranoside,benzyl-alpha-D-fructofuranoside and liquiritigenin were core components.PPI network and KEGG enrichment analysis found that Brassica rapa could treat hyperlipemia by regulated the core targets,such as VEGFA,IL6,EGFR and PPARG,and affected 36 signaling pathways(including starch and sucrose metabolism,galactose metabolism,insulin resistance,HIF-1,PI3K-Akt).Conclusion:This study showed that BRAE had excellent hypolipidemic activity in vitro,and preliminarily revealed the multi-component,multi-target,multi-path mechanism in the treatment of hyperlipidemia by network pharmacology approach,which provides a scientific foundation for further study. 展开更多

Objective: The chemical finger printing-based methods for evaluating TCMs quality can report partial of TCMs quality without linking to effective constituents. In this study, a mathematical model was established for the quality evaluation of total saponins of Panax japonicus(TSPJ), a folk medicine in China and Japan for treating diseases, through coupling the dynamic changes of chemical constitutions with corresponding activities.Methods: High-performance liquid chromatography(HPLC) fingerprints were applied to establish the chromatographic database of TSPJ. The associated hypolipidemic activity database was determined by TG assay using Hep G2 cell model. Correlation analyses of two databases were performed by partial least squares(PLS) for calculating regression coefficients, and the interval value of YZL value(the ratio of positive and negative peak-to-peak area coefficient) closely related to hypolipidemic activity was refined by the formula of Norminv function to value the quality of TSPJ.Results: In this study, the chromatographic data of 16 common peaks were obtained from 20 batches of TSPJ. After the estimate by this mathematical evaluation model, seven peaks were positively correlated with hypolipidemic activity, and nine peaks were negatively correlated with hypolipidemic activity.When the YZL value was less than 0.7861, the quality of sample was inferior, while YZL value was more than 6.6992, and the quality of samples was superior. The quality of another ten batches of TSPJ was further assessed to verify this method.Conclusion: These results indicated that the established model could be usefully applied to evaluate the quality of TSPJ in the hypolipidemic activity. 展开更多

Objective:To evaluate the effect of aqueous leaf extract of Cistus ladaniferus(C.ladaniferus) on glycemic and lipidemic status in diabetic rats.Methods:Overnight fasted rats were injected intraperitoneally with streptozotocin(45 mg/kg) to induce experimental diabetes.The aqueous extract of the leaves of C.ladaniferus was administered orally at the dose of 500 mg/kg body weight to diabetic rats for a period of 28 days.Hypoglycemic effect,body weight,oral glucose tolerance,change in lipid parameters,urea,creatinine,aspartate aminotransferase and alanine aminotransferase levels of diabetic rats treated with aqueous extract were evaluated in experimental animals.Results:Administration of 500 mg/kg of C.ladaniferus extract to diabetic rats for 28 days resulted in a significant reduction in the levels of blood glucose,alanine aminotransferase,aspartate aminotransferase,urea and creatinine.Furthermore,the extract of C.ladaniferus improved glucose tolerance in diabetic rats,and its antidiabetic effect was similar to the one obtained with glibenclamide.The hypolipidemic effect was demonstrated by an important decrease in plasma total cholesterol,triglycerides and low density lipoprotein-cholesterol levels.Conclusions:It is concluded that C.ladaniferus leaf extract showed an antidiabetic activity in experimental diabetes which was similar to the one obtained with glibenclamide. 展开更多

Objective:Wild musk melon(Cucumis melo var.agrestis,CMA)is one of the edible plants form Tamil Nadu.Traditionally,this plant was used as diabetic diet(leaves of CMA with Momordica charantia leaves),but there is no scientific report on antidiabetic action of this plant material.Hence,the current research work was designed to evaluate the antihyperglycemic and antihyperlipidemic effect of hydroalcoholic extract of CMA leaves(HALEC)in streptozotocin(STZ)-nicotinamide(NIC)-induced diabetic rats.Methods:Diabetes was induced by administration of STZ(60 mg/kg,i.p.)after 15 min of NIC(120 mg/kg i.p.)administration.The diabetic rats were treated with HALEC(300 and 600 mg/kg,p.o.,respectively)for 21 d.Results:After the management with HALEC,blood glucose,HbA1c levels,total cholesterol,LDL cholesterol,triglycerides levels,glycogen phosphorylase and glucose-6-phosphatase levels were significantly diminished in diabetic rats.However,haemoglobin level,HDL cholesterol,liver glycogen,total protein,hexokinase,glucose-6-phosphate dehydrogenase levels were significantly increased in HALEC treated diabetic rats.The histopathological studies of the pancreas in HALEC-treated diabetic rats showed almost normal appearance.L6 cell line study revealed the increased glucose uptake activity of HALEC.High performance thin layer chromatography(HPTLC)analysis confirms the presence of active principles such as rutin,gallic acid and quercetin in HALEC.Conclusion:The results indicated that HALEC possess significant antihyperglycemic and antihyperlipidemic activity in STZ-NIC-induced typeⅡdiabetic rats with protective effect.This research work will be useful for the isolation of active principles and development of herbal formulation in phytopharmaceuticals. 展开更多
