警犬血浆内源性代谢物的GC-MS分析

Gas chromatograph-Mass Spectrometry based on methodology was developed to investigate the endogenous metabolites in police dog’s plasma of German shepherd, English Springer Spaniel and Labrador Retriver. The results showed that there were more than 200 metabolites in canine plasma, and 38 endogenous metabolies were selected as the commensal metabolites in the three species. The major commensal metabolites were low molecular weight compounds include amino acids, fatty acids, carbohydrates and so on. Through the analysis of the 38 commensal endogenous metabolites, we found the concentrations of some metabolites among the three species there were differences.
