Fig. 4From: Mass spectrometry-based metabolomics study for delay tomato fruit ripening by sound wavesBoxplot of each metabolite identified in LC–MS analyses. The 11 metabolites were quantified based on LC–MS signals, and boxplots for 11 metabolites were drawn. LC–MS, liquid chromatography–mass spectrometry; LPC, lysophosphatidylcholineBack to article page
