This study was performed to study the effects of Gastrodiae rhizoma on lipid concentration of serum and liver in rats fed high fat diet. Male Sprague-Dawley rat were randomly assigned to 5 groups such as basal diet only(BDG), high fat diet(HFG) and high fat diet with 5% processed Gastrodiae rhizoma(GRL), high fat diet with 10% processed Gastrodiae rhizoma(GRM), high fat diet with 15% processed Gastrodiae rhizoma(GRH) supply each of the experimental diets for 6 weeks. Food intake was significantly decreased by both high fat intake and high fat with Gastrodiae rhizoma intake compared with basal diet intake but weight gain was not significantly different from each groups. Liver weights were significantly lowered by Gastrodiae rhizoma intake compared with high fat intake. In the serum, total cholesterol was not significantly different with each groups, but triglyceride level was significantly lowered by Gastrodiae rhizoma intake as compared with control. In the liver, lipid levels inceased with the Gastrodiae rhizoma intake, but total cholesterol and triglyceride levels were not significantly different with control. These results showed that dietary Gastrodiae rhizoma as supplementary food may decrease triglyceride in the serum.
