Abstract
A metabonomics-based tobacco leaf mildewing identification method, which comprises: obtaining tobacco leaf samples of the same variety, and carrying out artificial mildewing on a certain amount of tobacco leaf samples to obtain mildewed tobacco leaves; measuring volatile and semi-volatile components in the tobacco leaves before and after the tobacco leaf samples are mildewed by adopting a solid phase microextraction-gas chromatography-mass spectrometry method; performing data processing on the collected mass spectrum data to obtain the proportion content of different types of compounds in the mildewed sample and the normal sample, and further obtaining the change difference of the content of volatile compounds in the tobacco leaf sample before and after mildewing; and establishing a tobacco leaf mildewing identification model according to the discrimination variables.
