ESI (−) MS, MS2, and MS3 spectra of identified saponins in adzuki bean. Peak 14 (E): E-1 MS spectrum of peak 14 ([M−H]), E-2 MS2 spectrum of the ion at m/z 779, E-3 MS3 spectrum of the ion at m/z 617. Peak 15 (F): F-1 MS spectrum of peak 15 ([M−H]), F-2 MS2 spectrum of the ion at m/z 809, F-3 MS3 spectrum of the ion at m/z 647
