Citrus peel extract and powder attenuate hypercholesterolemia and hyperglycemia using rodent experimental modeling

Objective: To investigate hypocholesterolemic and hypoglycemic potential of citrus peel extract and powder using rodent experimental modeling.Methods: Considering the fact, rat feeding trial was carried out for a period of 56 d to access the prophylaxis of citrus peel flavonoids by employing normal(study Ⅰ),hyperglycemic(study Ⅱ) and hypercholesterolemic(study Ⅲ) rats. Each study was further divided into three groups to ensure the provision of selected diets, i.e.,control, functional and nutraceutical diets. Each study was further divided into three groups to ensure the provision of selected diets, i.e., control, functional and nutraceutical diets.Results: Declining trend for total cholesterol was observed in all studies with maximum reduction(8.55%) in rat group fed on nutraceutical diet in study Ⅲ. Likewise, levels of low density lipoproteins and triglycerides reduced 11.39% and 7.89% respectively in hypercholesterolemic rats. Moreover, nutraceutical diet alleviated the sera glucose level by 8.96% in study Ⅱ.Conclusions: Conclusively, inclusion of citrus peel bioflavonoids in dietary therapies is a promising strategy to modulate lipidemic and glycemic attributes without imparting any deleterious effect on hematological parameters.

Anti-hypercholesterolemic and anti-hyperglycaemic effects of conventional and supercritical extracts of black cumin(Nigella sativa)

Objective: To explore the hypoglycaemic and hypocholesterolemic potential of conventional and supercritical extracts of black cumin.Methods: Purposely, rat modelling was carried out for 2 months by designing three studies i.e. study Ⅰ(normal rats), study Ⅱ(hyperglycaemic rats) and study Ⅲ(hypercholesterolemic rats). Each study was further divided into three groups based on diet i.e.control, functional diet(contained extract of black cumin prepared by using conventional solvent) and nutraceutical diet(contained extract of black cumin prepared by supercritical fluid extraction system).Results: During whole trial, an abating trend was observed in the level of serum cholesterol with maximum reduction(12.8%) in nutraceutical group of study Ⅲ. Low density lipoprotein and triglyceride level was also lowered maximum in study Ⅲ as17.1% and 11.6%, respectively. Whereas, highest decline in glucose level was in nutraceutical group of study Ⅱ as 11.2%.Conclusions: Inclusion of black cumin extracts in diet significantly lowers the occurrence of hyperglycaemia and hypercholesterolaemia. Furthermore, hypoglycaemic and hypocholesterolemic potential of nutraceutical diet is more prominent as compared to functional diet.

Evaluating therapeutic potential of coriander seeds and leaves(Coriandrum sativum L.) to mitigate carbon tetrachloride-induced hepatotoxicity in rabbits

Objective: To evaluate the hepatic and renal protective potential of coriander seeds and leaves using animal feed model. Methods: Coriander seeds-and leaves-based sauces were administrated to normal(Study Ⅰ) and carbon tetrachloride(2 mL/kg B.W.)-induced hepatotoxic rabbits(Study Ⅱ). Hepatic and renal biomarkers like aspartate aminotransferase,alanine aminotransferase. alkaline phosphatase, superoxide dismutase and catalase were measured. Results: Coriander leaves-based sauce exerted more decline(P<0.05) in serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase levels in the study Ⅱ as 18.32%. 19.91% and 21.24%, respectively. While, hepatic superoxide dismutase and catalase levels were raised significantly(P<0.05) in both studies. Renal parameters also depicted positive impact by the provision of developed sauces. Conclusions: Coriander seeds and leaves based sauces are effective in alleviating the hepato/renal toxicity. The hepatoprotective effect of coriander leaves is more pronounced as compared to coriander seeds.
