The effects of dried green tea leaf powders on serum lipid concentrations were evaluated in rats. Sixty male Sprague-Dawley rats weighing 100±10g were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets: Normal fat diet and normal and high fat diets with 1% dried green tea leaf powders. Tissue weights of live, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by dried green tea leaf powders groups. The concentrations of serum triglyceride in rats fed the dried green tea leaf powers were lower than those in other groups. The concentrations of total cholesterol in green tea leaf powders the were lower powders green tea were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the dried green tea leaf powders groups were tended to be lower than those of other groups. GPT and GPT were decreased in dried green tea leaf powders groups and than in the high fat groups. LDHase was lower in the dried green tea leaf powders groups than in the high fat group. These results suggest that dried leaf powders green tea groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.
