    Abstract: This study investigated the hypolipidemic effect and potential mechanisms of T. mongolicum extracts. T. mongolicum was extracted by refluxing three times with water (TM-1), 50% ethanol (TM-2) and 95% ethanol (TM-3). TM-2 contained components with the most effective hypolipidemic potentials in HepG2 cells. Extended administration of TM-2 stimulated a significant reduction in body weight and levels of serum triglyceride LDL-C and total cholesterol in rats. To evaluate the bioactive compounds, we successively fractionated TM-2 with n-hexane (TM-4), dichloromethane (TM-5), ethyl acetate (TM-6), and water (TM-7). TM-4 fraction had the most effective hypolipidemic potential in HepG2 cells, and it decreased the expression of fatty acid synthase (FASN) and inhibited the activity of acetyl-coenzyme A carboxylase (ACC) through the phosphorylation of AMP-activated protein kinase (AMPK). Linoleic acid, phytol and tetracosanol are bioactive compounds identified from TM-4. These results suggest that T. mongolicum is expected to be useful for hypolipidemic effects.
