Obesity, metabolic syndrome and diabetes are epidemic chronic situations in industrialized countries that are associated with the reduction of life quality and increase of patients’ mortality. Before the serious epidemiological picture and the impact that the diabetes causes in the society, the use of different therapeutic interventions is priority in the scientific community. Thus, the goal of this work valued the hypoglycemic effect of the aqueous and methanolic extracts of the leaves of Cnidoscolus quercifolius Pohl (faveleira). The phytochemical analysis demonstrated the carbolic acids presence, flavonols, xanthone, catechin, triterpenoids, tannin and coumarins in both extracts and the liquid chromatography of high efficiency revealed the presence of the gallic acid; a powerful metabolite antioxidant. The Diabetes was induced in mice Swiss with alloxan that they did not present mortality when treated with 100, 200 mg / kg of methanolic extract and 100, 200 and 400 mg / kg of aqueous extract for 30 days. Histopathological analysis of the animal’s organs (kidney, pancreas, liver) did not reveal architectural alteration. All the diabetic animals submmited to the extracts presented a higher reduction on the blood sugar level percentage than the ones which were undergone to the standard drug. It is important to highlight that the blood sugar level - of the diabetic animals undergone to 400 mg / kg of weight of the aqueous extract - presented glycemic reduction of 39,81 % after 30 days of treatment. These results are very promising because they show great potential for the use of this typical Brazilian Caatinga plant as an alternative therapeutic option to slow down or reduce the risk of hyperglycemia and oxidative stress in diabetic patients. |
