The effects of pine needle extracts on serum and liver lipid contents were evaluated in rats. Thirty male Sprague-Dawley rats weighing 329$pm$4 were divided into five groups and fed high fat diets for four weeks. Each group was administered with following pine needle extract: control, water ; WE-3, hot water extract(3% PN) ; WE-6, hot water extract(6% PN) ; AE-3, acetone extract(3% PN) ; AE-6, acetone extract(6% PN). Weight gains were significantly lower in WE-6 group than other groups. But there was no significant difference among other three groups. Intakes of diet and water containing the extract and the weights of liver, kidney, heart and spleen were not significantly different among the groups. The contents of serum and liver triglyceride in the WE-3 group were lower than those of control group. The contents of HDL-cholesterol in serum of the WE-3 group was significantly higher than other groups. The value of risk factor index(RFI) was determined to be low especially in case of WE-3 group. Due to pine needle extract administration, concentration of liver total lipid in WE-3 group was significantly lower than that of the control group. These results suggest that the WE-3 may reduce elevated levels of serum and liver lipid contents in rat fed high fat diet.
