摘要：

Insect wax is a traditional Chinese medicine, which can be converted into policosanol through a reduction reaction. The efficacy of policosanol from insect wax (PIW) depends on its purity and composition ratio. Plant derived policosanol has a hypolipidemic effect, however, the effects of PIW on serum lipid levels have not yet been clarified. In this study, we investigated the effects of orally administered PIW on lipid metabolism in rats fed a high-fat diet. We found that PIW administration reduced the serum lipid levels of rats fed a high-fat diet, ameliorated body weight gain, and alleviated liver fat accumulation. This effect could be associated with the upregulation of fatty acid breakdown-and lipid metabolism-related genes, Ppar alpha and Ppar beta/delta, downregulation of fatty acid absorption and storage-related genes, Srebp1c, Il6, and Tnf alpha, and an antioxidant effect. These findings suggest the potential utility of PIW for developing functional foods with lipid-lowering capabilities.
