Objective: Cymbopogon citratus extract has been reported to have hypoglycemic properties but not much is known about its hypolipidemic effects. In this study it was aimed to demonstrate the hypolipidemic and hypoglycemic potentials of Cymbopogon citratus extract on alloxan-induced diabetic rats. Methods: Eighteen male albino rats of weights between 106-118 g were used for the study and divided into three groups of six rats each. The rats of the non-diabetic control group were given 1 ml of distilled water daily. Two other groups induced with diabetes using alloxan by a single dose administration of 120 mg/kg body weight (BW); one of these diabetic rat groups were treated with Cymbopogon citratus extract daily at 1.5 ml/100 g BW for 4 weeks while the other group was left untreated. Blood samples were collected and total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and glucose levels were assayed. Results: After four weeks of treatment, data indicated significant reductions in BW, blood glucose, TG, TC and LDL levels of diabetic rats treated with Cymbopogon citratus extract compared to the non-treated group. The treated diabetic rats also indicated significantly higher HDL levels compared to the non-treated group. Conclusion: Treatment of diabetic rats with the Cymbopogon citratus extract lowered blood glucose, TG, TC and LDL levels and increased the HDL level. This shows that the extract has both hypoglycemic and hypolipidemic effects.
