Abstract

Cardiovascular diseases with an incidence of approximately 50% are the main causes of death in most advanced countries and an increasing trend in the developing world as well. The World Health Organization estimates that 12 million people per year worldwide die from cardiovascular diseases. Cardiovascular diseases are becoming an increasing problem worldwide and hypercholesterolemia has been correlated for coronary heart diseases. Nearly all lipoproteins are involved in this process including cholesterol carried by very low density lipoproteins (VLDL), remnant lipoproteins and low density lipoproteins (LDL). Currently, available hypolipidemic drugs have been associated with the number of side effects. Herbal treatment for hyperlipidemia poses no side effects and is relatively cheap and locally available. In view of this, the present study was carried out to investigate the effect of Menthe piperita on serum lipid levels of albino rats. Mentha piperita aqueous extract (100 mg/Kg, 250 mg/Kg p.o. daily) was fed for 3 weeks on fructose-fed rats and the levels of glucose, cholesterol, triglycerides, very low density lipoprotein, low density lipoprotein, and atherogenic index was measured. Twenty-four male Sprague Dawley rats were divided into four groups (6 per group). The results of present study indicate that Mentha piperita had significant beneficial effects against fructose-induced hyperlipidemia and showed good antioxidant activity. The aqueous extract of the plant produced a significant decrease (p < 0.05) in elevated levels of glucose, cholesterol, triglycerides, very low density lipoprotein, low density lipoprotein and atherogenic index and also increased the high density lipoprotein cholesterol levels and HDL-ratio without affecting serum insulin levels in fructose-fed rats.
