Fig. 2From: Mass spectrometry-based metabolomics study for delay tomato fruit ripening by sound wavesRepresentative A LC–MS chromatogram for tomatoes using samples ripened for 7 d and B GC–MS chromatogram from one quality control sample. The numbers in the chromatograms represent the identified peaks matched with Tables 1 and 2.
