Abstract
AIM OF THE STUDY
The present study was carried out to isolate and identify trans-tiliroside as principal compound with anti-hyperglycemic, anti-hyperlipidemic and antioxidant effects from Potentilla chinesis.
MATERIALS AND METHODS
A bioactive compound, trans-tiliroside was isolated from the ethanol extract of Potentilla chinesis and its administration dose was optimized and patented. The normal, alloxan-induced diabetic mice and streptozotocin-induced diabetic rats were used to evaluate the anti-hyperglycemic, anti-hyperlipidemic and antioxidant effects of trans-tiliroside from Potentilla chinesis. Biochemical parameters were assayed in blood samples of different groups of alloxan-induced diabetic mice and streptozotocin-induced diabetic rats.
RESULTS
The level of fasting serum glucose levels, triglycerides (TG) and total cholesterol (TC) in alloxan-induced diabetic mice were significantly decrease after daily oral administration of trans-tiliroside in normal and diabetic mice at doses of 0.4, 0.8 and 1.6 mg/kg/day, for 15 days. Blood glucose level was significant decrease in STZ induced diabetic rats by trans-tiliroside (1.2 and 0.3mg/kg body weight for 10 weeks). The content of TC, low density lipoprotein (LDL-C) and TG levels were decreased and high density lipoprotein (HDL-C) content was increased, so lipid metabolism was improved. Moreover, trans-tiliroside revealed antioxidant activity as shown by increased activities of superoxide dismutase (SOD), decreased level of malondialdehyde (MDA) in diabetic rats. Histological morphology examination showed that the trans-tiliroside restored the damage of pancreas tissues in rats with diabetes mellitus.
CONCLUSION
Trans-tiliroside, a constituent from Potentilla chinesis, revealed significant anti-hyperglycemic, anti-hyperlipidemic and antioxidant activities.
