Hyperlipidemia is an associated complication of diabetes mellitus. In the present study, we investigated the effect of tetrahydrocurcumin (THC), one of the active metabolites of curcumin on lipid profile in streptozotocin (STZ)-nicotinamide-induced diabetic rats. THC 80 mg/kg body weight was orally administered to diabetic rats for 45 days, resulting in a significant reduction in blood glucose and a significant increase in plasma insulin in diabetic rats, which proved that THC possess an antidiabetic effect. THC also caused a significant reduction serum and liver cholesterol, triglycerides, free fatty acids, phospholipids, HMG CoA reductase activity, very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) cholesterol levels. The decreased serum high-density lipoprotein (HDL) cholesterol in diabetic rats was also reversed toward normalization after the treatment. These biochemical observations were supplemented by histopathological examination of liver section. The effect was compared with curcumin (80 mg/kg body weight). The results showed that THC had antihyperlipidemic action in control and experimental diabetic rats. The antidiabetic and antihyperlipidemic effects of THC are more potent than those of curcumin at the same dose.
