Dietary antioxidant compounds such as flavonoids may offer some protection against early-stage diabetes mellitus and its complications. Abnormalities in both glucose metabolism and lipid profile constitute one of the most common complications in diabetes mellitus. The present study aimed to evaluate the effect of rutin, through biochemical parameters, on experimental streptozotocin (STZ)-induced diabetes in rats. Male Wistar rats were divided into four groups: untreated controls (GI); normal rats receiving rutin (GII); untreated diabetics (GIII); diabetic rats receiving rutin (GIV). STZ was injected at a single dose of 60 mg kg(-1) to induce diabetes mellitus. The diabetes resulted in increased serum glucose, cholesterol, triacylglycerols and lipoproteins (LDL and VLDL-cholesterol) but decresed serum HDL-cholesterol and insulin. Rutin (50 mg kg(-1)) reduced (p<0.05) blood glucose and improved the lipid profile in STZ-induced diabetic rats. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) activities were significantly augmented in serum of STZ-diabetic rats, while these activities were diminished in hepatic and cardiac tissues compared with the control group. Rutin prevents changes in the activities of ALT, AST and LDH in the serum, liver and heart, indicating the protective effect of rutin against the hepatic and cardiac toxicity caused by STZ. Rutin was associated with markedly decreased hepatic and cardiac levels of tryacylglycerols and elevated glycogen. These results suggest that rutin can improve hyperglycemia and dyslipidemia while inhibiting the progression of liver and heart dysfunction in STZ-induced diabetic rats.

Metabolic syndrome (obesity, diabetes, and hypertension) increases hepatic and cardiovascular damage. This study investigated preventive or reversal responses to rutin in high-carbohydrate, high-fat diet-fed rats as a model of metabolic syndrome. Rats were divided into 6 groups: 2 groups were fed a corn starch-rich diet for 8 or 16 wk, 2 groups were fed a high-carbohydrate, high-fat diet for 8 or 16 wk, and 2 groups received rutin (1.6 g/kg diet) in either diet for the last 8 wk only of the 16-wk protocol. Metabolic changes and hepatic and cardiovascular structure and function were then evaluated in these rats. The corn starch-rich diet contained 68% carbohydrate (mainly cornstarch) and 0.7% fat, whereas the high-carbohydrate, high-fat diet contained 50% carbohydrate (mainly fructose) and 24% fat (mainly beef tallow) along with 25% fructose in drinking water (total 68% carbohydrate using mean food and water intakes). The high-carbohydrate, high-fat diet produced obesity, dyslipidemia, hypertension, impaired glucose tolerance, hepatic steatosis, infiltration of inflammatory cells in the liver and the heart, higher cardiac stiffness, endothelial dysfunction, and higher plasma markers of oxidative stress with lower expression of markers for oxidative stress and apoptosis in the liver. Rutin reversed or prevented metabolic changes such as abdominal fat pads and glucose tolerance, reversed or prevented changes in hepatic and cardiovascular structure and function, reversed oxidative stress and inflammation in the liver and heart, and normalized expression of liver markers. These results suggest a non-nutritive role for rutin to attenuate chronic changes in metabolic syndrome.

Several lines of evidence suggest that flavonoids that originated from vegetables and medicinal plants have beneficial effects on diabetes by improving glycemic control, lipid profile, and antioxidant status. Rutin is a flavonoid found in many plants and shows a wide range of biological activities including anti-inflammatory, antioxidant, neuroprotective, nephroprotective, and hepatoprotective effects. In this review, the antihyperglycemic property of rutin and its protective effects against the development of diabetic complications are discussed. Proposed mechanisms for the antihyperglycemic effect of rutin include a decrease of carbohydrates absorption from the small intestine, inhibition of tissue gluconeogenesis, an increase of tissue glucose uptake, stimulation of insulin secretion from beta cells, and protecting Langerhans islet against degeneration. Rutin also decreases the formation of sorbitol, reactive oxygen species, advanced glycation end-product precursors, and inflammatory cytokines. These effects are considered to be responsible for the protective effect of rutin against hyperglycemia- and dyslipidemia-induced nephropathy, neuropathy, liver damage, and cardiovascular disorders. Taken together, the results of current experimental studies support the potential of rutin to prevent or treat pathologies associated with diabetes. Well-designed clinical studies are suggested to evaluate advantages and limits of rutin for managing diabetes.
