Fig. 2 in Assessing specialized metabolite diversity of Alnus species by a digitized LC-MS/MS data analysis workflow

Fig. 2. The MS/MS spectral network of specialized metabolites contained in the bark, twigs, leaves, and fruits of A. japonica, A. firma, A. hirsuta, and A. hirsuta var. sibirica. Spectral nodes are colored according to the mean precursor ion intensity per different plant parts: bark, twigs, leaves, and fruits. Molecular families A–I are highlighted.
