Abstract
Acetone-and water-extracted roasted tea samples (Hoji-cha) were mixed in the diet along with lard, and administered to rats for 2 weeks. Effects of administraction on serum total cholesterol and triglycerides and fatty acid in serum and the liver were measured and studied. Following results were obtained.
1) Increase of serum total cholesterol was inhibited by the water extract, and triglyceride by acetone extract.
2) Total polyenoic acid contents of total lipid of serum and the liver were low in rats administered the water extract, but high in those administered the acetone extract.
3) Body weight gain of the animals administered acetone extract was less than those administered water extract.
