Fig. 5. Pea pod anatomy and MALDI mass spectrometry imaging of pisatin (1) and pinoresinol monoglucoside (4). (A) Cross-section of pea pod stained with toluidine blue O. (B—G) MALDI MSI positive ion images of pisatin (1; m/z 297.0753, [M—H O+H] +; B—D) and pinoresinol monoglucoside (4; m/z 559.1590, [M+K] +; E—G) presented in ratio of 2 histology image layer (tissue image): data image layer (MALDI MSI image) for image layer opacity using HDImaging TM (V1.1) software at 100:100 (B, E), 25:50 (C, F) and 0:100 (D, G), respectively. The epidermal cell layer in the area to the right of the dotted line has been removed.
