Abstract
The effects of water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower on serum lipid concentrations were evaluated in rats. Forty-eight male Sprague-Dawley rats weighing l00±l0 g were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Control diet, animal, plant high fat diet and control and high fat diets with 2% water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups. The concentrations of serum triglyceride in rats fed the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower were lower than those in other groups. The concentrations of total cholesterol in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower group were lower than those in high fat diet groups. The concentrations of HDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were tended to be lower than those of other groups. GPT and GOT activities were decreased in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups and than in the high fat group. LDH activity was lower in the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups than in the high fat group. These results suggest that water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.
