Anti-hyperlipidemic effect of red ginseng (RG; the steamed root of Panax ginseng C.A. Meyer) and Crataegii fructus (CF, the fruit of Crataegus pinnatifida BGE), which are used frequently in China and Korea as herbal medicines to treat arteriosclerosis, were investigated. Treatments of RG and CF significantly reduced blood triglyceride (TG) and total cholesterol (TC) levels in Triton WR-1339-induced hyperlipidemic mice and serum TG levels in corn oil-induced hypertriglyceridemic mice. Ginsenoside Rg3 and ursolic acid, the main constituents of RG and CF, respectively, also reduced TG and TC levels in hyperlipidemic mice. RG and CF significantly lowered the high blood TG and TC levels and body and epididymal mass weights induced by long-term feeding of a high-fat diet and increased the high-fat diet-induced decrease in blood HDL cholesterol levels. RG and Rg3 reduced the blood TC levels more than CF and ursolic acid. However, blood TG level were reduced by CF and ursolic acid more than RG and Rg3. RG, CF, and their constituents also inhibited pancreatic lipase and HMG-CoA reductase activities. The most potent inhibitor was Rg3. These findings suggest that RG and CF may be suitable for the therapies of hypercholesterolemia and triglyceridemia, respectively.
