Effect of the treatment with Euterpe oleracea Mart. oil in rats with Triton-induced dyslipidemia

Abstract

Objectives: Dyslipidemias are defined as changes in lipid metabolism that have abnormal concentrations of lipids or lipoproteins in the bloodstream. Chronic increase in triglyceride and low-density lipoprotein (LDL-c) levels are known as risk factors for the atherogenesis process as well as other cardiovascular diseases (CVDs). The magnitude of the problems caused by dyslipidemias impels research by new agents that act in the prevention and control. Thus, products from the Amazonian biodiversity, such as Euterpe oleracea oil (OFEO), rich in unsaturated fatty acids (UFAs), constitutes a study source for the treatment of alterations in lipid metabolism.

Methods: The present study aims to investigate the effect of OFEO treatment in rats with Triton-induced dyslipidemia (Tyloxapol WR1339).

Results: The physicochemical and chromatographic results confirmed the chemical composition of OFEO with a predominance of UFAs (67.83%), with Oleic acid being the majority (54.32%). At Triton-induced dyslipidemia, the animals treated with OFEO and Simvastatin showed a significant reduction in total cholesterol levels, with values ​​of 121.7±29.5 (p<0.01) and 96.6±17.6mg/dL (p<0.001), respectively. OFEO also significantly reduced LDL-c levels (p<0.01) and triglycerides (p<0.001). OFEO and Simvastatin improved the lipid profile by significantly increasing (p<0.05) the high-density lipoprotein (HDL) values.

Conclusions: Therefore, it is concluded that the OFEO treatment used in the conditions of this study had a beneficial effect on dyslipidemia, acting as antihypercholesterolemic and antihypertriglyceridemic, thus possibly contributing as a preventive agent for CVDs.
