Abstract

The mechanism for the plasma and liver triacylglycerol-reducing effects of Japanese torreya (Torreya nucifera) seed oil containing sciadonic acid (all-cis-5, 11, 14-eicosatrienoic acid) is reported. Male SD rats were fed experimental diets containing 10% torreya, corn, or soybean oil for 4 weeks, and the activities and mRNA expression of the enzymes involved in lipid metabolism were measured in the liver. The activities of some hepatic enzymes involved in fatty acid synthesis were lower in the rats fed torreya oil.
