dc.description.abstractNatural products have been used in tratamed of hypercholesterolemia. The bee products have been promoting up the man's interest, among them it stands out the propolis, coleted by bees, rich in polyphenols. The biggest polyphenols of propolis was flavonoids and caffeic acids, which have antioxidant power, presenting the protective action to the lipoprotein LDL-cholesterol against the lipid peroxidation. Therefore, the present work was evaluated whether the caffeic acids of the Botucatu's propolis (Botucatu-SP) affect the levels of plasma cholesterol, in rabbits submitted to the rich diet in cholesterol. The animals were divided in three groups: C (n=2) they received commercial ration and water for the whole period; S (n=2) they received normal ration and water in the first period and supplemented ration and water in the second and third periods; S+T (n=5) they received normal ration and water in the first period, supplemented ration and water in the second period and supplemented ration and extract rich in caffeic acids in the third period. The caffeic acids were administered diluted in water, being in the concentration of 0.05g caffeic acid mL -1 kg -1 of animal. Weekly, after fast of 14 hours, the samples of blood were collected from the marginal vein of the ear for determination of the plasma levels of total cholesterol and their fractions. The caffeic acids of the propolis reduced the plasma concentration of total cholesterol in 30% (280 for 199 mg dL -1) in the rabbits treated with flavonoids, while in the animals of the group S those levels were reduced discreetly (380 for 400 mg dL -1). The animals of the group C maintained this biochemical parameter in the normality range during the whole period (50 mg dL -1). Therefore, we concluded that the caffeic acids exert inhibititory activity in the metabolism of the cholesterol, being considered as a substance of action against the hypercholesterolemia.en
