Isolation and characterization of hypocholesterolemic bioactive agent extracted from Monascus purpureus FTC5391

One of the basic causes of mortality in developed countries is cardiovascular disease,especially coronary heart disease. Control of blood cholesterol level is important to avoid cardiovascular disease. In this study the bioactive compound(s) of Monascus purpureus FTC5391 with hypocholesterolemic po...
