Quantitative detection method of multiple metabolites in biological sample and metabolic chip

Abstract

The present invention discloses a quantitative detection method of multiple metabolic components in a biological sample and a metabolic chip used in the method. The detection method includes performing derivatization treatment on the biological sample and then detecting the derivatized biological sample by liquid chromatography-mass spectrometry. During derivatization treatment, 3-nitrophenylhydrazine is used as a derivatization reagent, and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide is used as a derivatization reaction catalyst. According to the detection method of the present invention, high-sensitivity detection can be achieved, multiple metabolic components of different magnitudes can be detected, the operation is simple and fast, and the method is applicable to clinical detection and scientific research examination. The metabolic chip of the present invention includes a chip carrier microtiter plate and related reagents, and quantitative detection of multiple metabolic components of different magnitudes such as amino acid, phenol, phenyl or benzyl derivative, indole, organic acid, fatty acid, sugar, and bile acid in the biological sample on the same microtiter plate can be achieved.
