Changes of Metabolomic Profile in Helianthus annuus under Exposure to Chromium(VI) Studied by capHPLC-ESI-QTOF-MS and MS/MS

Figure 6

Three first molecular formulas predicted in SIRIUS and MS-Finder for seven precursor ions (score values reported in parentheses, bold font indicates the pondered formula) and the extracted ion chromatograms of these ions acquired for two replicates of exposed and nonexposed roots, respectively (see Table 1 for the description of MF).
