Supplementary datasets for polyphenol widely targeted metabolomics analysis in walnut endopleura

It contains QC TIC and MRM XIC chromatograms (Fig. S1), sample correlation and CV distribution plots for instrument stability assessment (Fig. S2), together with five metabolite tables: all detected polyphenols (Table S1), 750 DAMs from pairwise comparisons (Table S2), 589 DAMs in heatmap Cluster 2 & 3 (Table S3), 426 multi-omics DAMs (Table S4), and 19 key metabolites in five core pathways (Table S5).

The dataset provides full metabolite information supporting the manuscript’s metabolomics results.
