Abstract Background Trifolium pratense (red clover) ethanolic extract (TPEE) has been used as a popular over-the-counter remedy for the management of menopausal symptoms. Prolonged consumption of herbal extract has been shown to regulate the composition of gut microbiota. This study was designed to elucidate the influence of TPEE on the gut microbiota composition in the ovariectomized (OVX) rats. Methods OVX rats were treated with TPEE at 125, 250, 500 mg/kg/day, or controls (pomegranate extract, 500 mg/kg/day; estradiol, 25 μg/kg/day) for 12 weeks. Gut microbiota analysis was conducted by extracting the microbial DNA from fecal samples and microbiome taxonomic profiling was carried out by using next-generation sequencing. The levels of serum biomarkers were analyzed using enzyme-linked immunosorbent assay (ELISA) kit. The prediction of functional biomarker of microbiota was performed using PICRUSt to investigate the potential pathways associated with gut health and serum lipid profile regulation. To study the correlation between gut microbiota composition and serum lipid levels, Spearman’s correlation coefficients were defined and analyzed. Additionally, gas chromatography–mass spectrometry analysis was conducted to uncover additional physiologically active ingredients. Results TPEE-treated OVX rats showed significant reduction in serum triglycerides (TG), total cholesterols (TCHOL), and LDL/VLDL levels but increase in HDL level. The alteration in the pathways involve in metabolism was the most common among the other KEGG categories. Particularly, TPEE also significantly reduced the relative abundance of sequences read associated with inflammatory bowel disease (IBD) and the peroxisome proliferator-activated receptor (PPAR) signalling pathway. TPEE intervention was seen to reduce the Firmicutes to Bacteroidetes (F/B) ratio in the OVX rats, denoting a reduction in microbial dysbiosis in the OVX rats. Correlation analysis at the phylum level revealed that Bacteriodetes and Proteobacteria were strongly correlated with serum TG, TCHOL and HDL levels. At the species level, Bifidobacterium pseudolongum group was seen to positively correlate with serum HDL level and negatively correlated with serum AST, ALT, LDL/VLDL, TCHOL, and TG levels. Conclusions TPEE treatment showed therapeutic benefits by improving the intestinal microbiota composition which strongly correlated with the serum lipid and cholesterol levels in the OVX rats.

 Objective: The study was aimed to evaluate the hypolipidemic and antioxidant effect of Triticum aestivum (wheat) bran extraction cholesterol-fed rabbits.Methods: The induced hyperlipidemic rabbits were treated with 70% ethanolic extract of wheat bran at a dose of 500 mg/kg body weight/day. The experimental protocol was designed for control, hyperlipidemic, wheat bran extract, and statin-treated groups for 60 days. The estimations for serum lipid profile, lipid peroxidation (LPO), and ferric reducing ability of plasma (FRAP) were done, and histopathological study of thoracic aorta was carried out.Results: Oral administration of wheat bran extract caused significant reductions in the serum lipid profile by 94.30% (total cholesterol), 96.73% (low-density lipoprotein cholesterol), and 58.28% (triglycerides). It significantly decreased the LPO and enhanced the antioxidant capacity (FRAP) activity as compared to the hyperlipidemic rabbits. Histopathology revealed that wheat bran extract treatment prevented the accumulation of cholesterol and regressed atheromatous plaques significantly in the aorta as compared to the hyperlipidemic group, and the results were comparable to that of the standard drug statin.Conclusion: The study exhibited that wheat bran extract controls atherosclerosis just like statin and can be used as a regular dietary supplement to manage cholesterol levels and prevent cardiovascular problems.

The aim of this study was designed to evaluate the activity of the Kigelia Pinnata ethanolic leaf extract on the serum lipid profile of male albino Wistar rats exposed to a fat diet. Kigelia Pinnata leaves were obtained, air dried, powdered and extracted in a Soxhlet apparatusin 400ml ethanol solution. Hypolipidaemic activity studies on rat models fed with palm oil and coconut milk was conducted. The acute toxicity test of the extract was carried out by the lorke's method. Results showed that Kigelia Pinnata ethanolic leaf extract significantly lowered (P<0.05) plasma Total Cholesterol (TC), Low Density Lipoprotein (LDL)-Cholesterol and Triacylglycerol (TG) and significantly (P<0.05) increased plasma High Density Lipoprotein (HDL)-Cholesterol. Toxicity studies suggested that, the extract was safe at the doze 2000mg/kg. Overall findings from this study showed that the ethanolic extract exhibited hypolipidaemic activity and may possess cardio-protective properties.

Objective: The study was aimed at evaluating the folkloric use of the Catunaregam spinosa (Thunb) bark for its hypoglycaemic and antioxidant activity against dexamethasone-induced diabetes in wistar rats. Methods: Diabetes was induced in wistar rats by dexamethasone administration 10 mg/kg, b. wt., s. c for 11 consecutive days to all group animals (except Group I). After confirmation of diabetes, the animals were divided into 5 groups (n=6). Group I: Vehicle control treated with normal saline only, Group II: Diabetic control treated with dexamethasone only, Group III: Standard control treated with dexamethasone plus glibenclamide (5 mg/kg, b. wt., p. o), Group IV and V: Test control received dexamethasone plus ethanolic extract of Catunaregam spinosa (EECS) at graded doses of 200 mg/kg, b. wt. and 400 mg/kg, b. wt., p. o for 21days respectively. On the last day of the experiment, the effect of Catunaregam spinosa bark was measured by estimating the biochemical and antioxidant parameters. Results: There was a significant alteration in the serum glucose, HbA1c, total proteins, serum lipid profile and tissue antioxidant parameters in dexamethasone-treated animals when compared to the normal control rats. In test groups treated with glibenclamide and EECS, it was significantly ameliorated the altered parameters such as serum glucose, HbA1c, total proteins, serum lipid profile and the antioxidant parameters like SOD, CAT, GSH and MDA when compared to dexamethasone-treated animals with evidence of histopathological studies of the pancreas. Conclusion: The results indicated that the ethanolic extract of Catunaregam Spinosa (Thunb) bark has shown the hypoglycemic and antioxidant property.
