Figure 4.
Gallic acid derivatives in the largest cluster of the network. Numbers inside the nodes correspond to the accurate mass for each precursor. Node size is proportional to the intensity of the ions in the total ion chromatogram. Node colors represent structural groups: gallic acid derivatives (G1, blue), flavan-3-ol derivatives (G2, orange) and flavone derivatives (G3, green). Rhomboid shapes correspond to a match against an experimental MS2; square shapes are identifications from in silico spectra matching.
