AFB2* | 1.3 | 10.9 | C17H14O6 | [M + H]+ | 315.0863 | –0.8 | 0.06 |
AFB1* | 1.6 | 11.4 | C17H12O6 | [M + H]+ | 313.0707 | –0.8 | 0.08 |
AFL* | 1.2 | 12.4 | C17H14O6 | [M-H2O + H]+ | 297.0757 | –1.5 | 0.09 |
*Confirmation with standard by comparison of accurate mass, HRMS/MS, and RT. All the metabolites were detected in both organs. The abundance, expressed as the peak chromatographic area, was always higher in roots than in leaves for all the annotated metabolites with the only exception of AFM1.
