Fator hipodislipemico do Olea europaea e Theobroma grandiflorum no plasma de ratos wistar e análíse comparativa de ácidos graxos presentes

Abstract

Dyslipidemia is a modification in blood levels of fat, one of the higher incidence of the pathologies in the world population, currently regarded as a public health concern. Some factors contribute greatly to increase cardiovascular diseases; among them, the lipid metabolism is one of most important. This factor is related to ingestion of lipid but the consumption of monounsaturated fatty acid (oleic) show neutral effect over cholesterolemy. However, it has been noticed that high oleic acid diets increase High Density Lipoprotein level (HDL-c) and may reduce the Low Density Lipoprotein level (LDL-c). The objective was to evaluate the Dyslipidemia Reduction Factor and compare the lipid profile and nutrition of the animals treated with the commercial diet supplemented and compare physicochemical fat and oil indexes using extra virgin olive oil and cupuaçu fatty seed. In this comparative study was used experimentally fat of cupuaçu seeds (Theobroma grandiflorum, Schum.) and olive oil (Olea europaea) extra virgin as a food supplementing in Wistar rats male youths. In the experiment were used six groups of eight animals and five of them were induced to dyslipidemia by use of monosodium glutamate. The applicability was 28 days which was provided usual feeding with supplemented of (0.1ml to 0.3ml) of one type of lipid in each group and gas chromatography and physicochemical analysis such as saponification, acidity, peroxide, and free fatty acid levels. So according to the procedures of gavage and oral route there was no difference, however between the lipidogram tests performed, Treatment with fat cupuaçu seed was what achieved the best action of Dyslipidemia Reduction Factor, except for HDL cholesterol that there was no difference in any treatment. Results show that extra virgin olive oil and cupuaçu fatty seed have same fatty acids; although, different amounts for these constituents. These results indicate that different quantities of same fatty acids on different levels may interfere on hipodislipidemic factor for cupuaçu fatty seed diets.
