Metabonomics data processing method and device based on stable isotope labeling

The invention discloses a metabonomics data processing method and device based on stable isotope labeling. The method specifically comprises the following steps: acquiring isotope information of a first annotation metabolite in a non-labeled sample; based on the isotope information, determining a reference isotope peak and a to-be-adjusted isotope peak in the isotope peaks of the to-be-analyzed sample according to a preset division condition; according to the chromatographic retention time and the peak boundary corresponding to the peak top point of the reference isotope, adjusting the chromatographic retention time and the peak boundary corresponding to the peak top point of the isotope to be adjusted to obtain a target isotope peak; respectively calculating a first isotope peak abundance value of the reference isotope peak and a second isotope peak abundance value of the target isotope peak; and correcting the first isotope peak abundance value and the second isotope peak abundance value through a natural i
