RESUMEN
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 nutra-ceutical 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.
RESUMEN
Objective: To evaluate the potential of both jamun (Syzygium cumini) seed and fruit extracts against hyperglycemia. Methods: Male Sprague Dawley rats were used to evaluate hypoglycemic potential of jamun extracts. Purposely, jamun fruit and seed's ethanolic extracts based diets were provided to normal and high sucrose diet induced hyperglycemic/diabetic rats for sixty days. The serum glucose and insulin levels were monitored at monthly intervals to evaluate hypoglycemic effect of jamun extracts. Results: The results of instant research depicted that both seed and fruit extracts reduce the blood glucose level significantly and also regulate the insulin levels in hyperglycemic rats. It was noted that jamun fruit extract attenuated serum glucose levels to 5.35％and 12.29％ in normal and hyperglycemic rats, respectively; while insulin levels were improved by 2.82％ and 6.19％, correspondingly. Whereas, jamun seed extract reduced glucose to 7.04％&14.36％and showed 3.56％&7.24％higher insulin levels in normal&hyperglycemic rats, respectively. Conclusions: The present research revealed that both jamun fruit and seeds have potent prophylactic role against hyperglycemia. In this respect, diet based regimen may be tailored using jamun fruit/seed and their extracts to alleviate hyperglycemia.
RESUMEN
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 rots).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 as 17.1％ 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.
