Through the map analysis of various metabolites in rat's urine, the biomarkers in syndrome suitable for Small Qing-Long Decoction (SQLD) were found out, which provided objective basis for the clinical diagnosis and treatment. Based on the rat's urine nuclear magnetic resonance (NMR) spectrum detection of the blank control group, the model group and the SQLD group, the data come from the map by MestRenova pretreatment and integration were analyzed using SIMCA-P+ by (PLS-DA). Then, the corresponding scatter diagram and diagram of loading were re-ceived and the differences of metabolites were found out by the comparison . The results showed that compared with the blank control group, contents of creatinine, guanidinoacetic acid, trimethylamine, taurine, allantoin metabolites in the model group had elevated. And the contents of succinic acid, 2-OG, lactic acid, glycine, methyl nicotine metabolite had decreased. After medication, contents of creatinine, trimethylamine, allantoin, taurine of SQLD group were still higher than the blank control group. However, the contents were reduced compared with the model group. The content of lactic acid was lower than the blank control group, but higher than the model group. There was no statistical significance on changes of guanidinoacetic acid, 2-OG, N-nornicotine. It was concluded that substances found were mainly related to energy metabolism, inflammation and immune resistance, which was especially related to energy metabolism change obviously.
