The study was designed to explore the influence of high-fat diet on the metabolism profile of feces and intestinal contents of golden hamster to provide new information for the mechanism of drug action. Twelve golden hamsters fed with high-fat diet and twelve golden hamsters fed with normal diet were used as model group and control group, respectively. Serum samples were collected from the normal group and the model group at 2 weeks, 4 weeks and 8 weeks after the induction of high-fat diet. Serum biochemical parameters were measured in the control and model groups. The levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) levels in model group were higher than the control group. After 8 weeks, the feces and intestine contents were taken. The intestine was divided into four sections:jejunum, ileum, cecum and colon. The changes of endogenous metabolites in intestinal contents were analyzed by 1H NMR based metabolomics combined with multivariate statistical analysis to find the significant differences in metabolites. The metabolic profiles of hyperlipidemia model group and control group were significantly distinguished by the othorgonal partial least squares-discriminate analysis, (OPLS-DA). Compared with the control group, the endogenous metabolites in feces such as amino acids, fatty acids, tricarboxylic acid cycle intermediates and nucleotides related to intestinal microflora were changed significantly (P < 0.05), and the amino acid metabolites, protein spoilage products and choline metabolites in intestinal contents had significant changes (P < 0.05). The data suggest that the intestinal microflora plays an important role in the development of hyperlipidemia in golden hamsters from the molecular level of metabolites. This result provides useful information for the clinical treatment of hyperlipidemia and development of hyperlipidemia drug.
