Maotai-flavor liquor component analysis method based on non-targeted metabonomics technology and application of Maotai-flavor liquor component analysis method

The invention belongs to the technical field of Maotai-flavor liquor detection and analysis, and relates to a Maotai-flavor liquor component analysis method based on a non-targeted metabonomics technology and application. The method comprises the following steps: (1) sampling: taking a Maotai-flavor liquor sample as a to-be-detected sample without sample pretreatment; (2) detecting and analyzing the to-be-detected sample on the basis of an ultra-high performance liquid chromatography-quadrupole electrostatic orbital field ion trap mass spectrometry technology, separating all components in the to-be-detected sample through ultra-high performance liquid chromatography, and directly measuring the components in a mass spectrometer; (3) qualitative analysis: performing qualitative analysis on the components in the sample to be detected based on the data measured in the step (2); wherein the chromatographic column of the ultra-high performance liquid chromatography is Infinity Lab Poroshell HPH-C18 (2.1 * 100 mm, 1
