FIGURE 4. MALDI-MS comparison of different Carapichea ipecacuanha tissues and samples.

FIGURE 4

(A) Offset-aligned MALDI-MS traces of two types of plant tissues from the same Herbarium sample (W-1922-0008476), i.e., leaf (back) and root (middle) as well as root-powder (front, WU-0067845) are shown. Most abundant peptide masses are labeled, and their presence in all three samples has been indicated by dashed lines. (B) A comparison of the distribution of observed peptide masses in all three samples is shown as a dot-chart. Displayed monoisotopic masses were obtained from DataExplorer™ software with signal-to-noise limit set to 5. Caripe 1 has a mass of 3268.3 Da and is highlighted in bold text.
