The biochemical variations of urine from chow- and high fat-fed rats were investigated using NMR-based metabolomics. Two groups can be discriminated clearly according to the scores plot of partial least squares discriminant analysis. The plot of variable importance in projection shows that taurine, succinate, hippurate, choline, citrate, dimethylamine, acetate, dimethylglycine, creatine, creatinine, tyrosine, glycine and lactate are contributed to the classification. In addition, the metabolic change with the development of obesity was also explored.
