The effect of hydroalcoholic extract and essential oil of Heracleum persicum on lipid profile in cholesterol-fed rabbits

This study was designed to investigate the effect of hydroalcoholic extract and essential oil of Heracleum persicum (Apiaceae) on lipid profile of male hyperlipidemic rabbits. Thirty rabbits were randomly divided into six groups of five each. One group received normal diet and the other groups fed with a high cholesterol (2% W/W) diet for 7 weeks. Vehicle, hydroalcoholic extract (500 and 1000 mg/kg), essential oil (200 ml/kg), and lovastatin (5 mg/kg) were administered orally to animals and their effects on lipid profile were evaluated. Essential oil of H. perscum significantly (p<0.05) lowered serum triglyceride level and increased HDL-cholesterol concentration. Moreover, hydroalcoholic extract (1000 mg/kg), essential oil (200 ml/kg), and lovastatin significantly (p<0.01) reduced serum concentration of total cholesterol and LDL-cholesterol. These findings suggest that essential oil of the plant fruits may have some benefits in reducing cardiovascular risk factors.
