COMPOSITION COMPRISING RUTIN AND QUERCETIN FOR PREVENTING AND TREATING HYPERLIPIDEMIA, ARTERIOSCLEROSIS AND LIVER DISEASE

摘要

PURPOSE: A pharmaceutical composition and a functional food comprising bioflavonoids are provided, for treating and preventing hyper lipidemia, arteriosclerosis and a liver disease. CONSTITUTION: The pharmaceutical composition comprises rutin, quercetin or their mixture ineffective amount; and pharmaceutically acceptable carriers. The functional food comprises 0.01-10 wt% of rutin, quercetin or their mixture. Rutin can be obtained from a fruit, a leaf, a trunk and a flower of buck wheat and be used in the form of a powder or an extract. Rutin and quercetin being bioflavonoids inhibit HMG CoA (3-hydroxy-3-methylglutaryl coenzyme) being a reduction enzyme which relates to the biosynthesis of cholesterol and ACAT (acyl CoA; cholesterol-O-acyltransferase) which transforms cholesterol into cholesteryl ester in the body. Therefore rutin and quercetin reduce the concentration of cholesterol in blood, inhibit strongly a macrophage-lipid complex from being deposited or adsorbed onto the intra trial surface, and protect a liver.
