The effect of oil phytopreparations on the lipid status in an experiment

Abstract

Aim. To study the effect of oil extracts of the burdock root and elecampane on the lipid profile in an experimental model of cholesterolosis. Methods. Experiments were performed on 60 white nonlinear rats, weighing 180-300 g. The oil extract from the burdock root was administered intragastrically at a dose of 2.5 ml/kg, and an extract from the root of elecampane - at a dose of 1.0 ml/kg during the last 30 days on the background of a cholesterol diet. After removal of the animals from the experiment the levels of cholesterol, triglycerides, high and low density lipoproteins, phospholipids, free fatty acids were determined in the blood serum and in liver homogenates with the use of standardized sets. Results. Administration of oil extracts of the burdock root and elecampane on the background of a cholesterol diet resulted in a significant reduction in serum cholesterol level by average of 1.48 times, triglycerides level - by 1.9 times, low-density lipoproteins level - by 1.8 times, as well as in a significant increase in the level of high-density lipoproteins on average by 1.5 times compared with the pathology model. In the same conditions the oil extracts of the burdock root and elecampane significantly increased the phospholipid content in the liver tissue by 1.4 and 1.7 times, respectively, the content of free fatty acids - by 2 times in average, the content of esterified cholesterol - by about 1.5 times as compared with the pathology model. Conclusion. The studied oils have a unidirectional positive effect on the lipid content in blood serum and liver in an experimental cholesterolosis; the oil extract from the root of elecampane has a more pronounced effect.
