Kaempferol fragment ions

The MS3[(M—H) Yq] event (Figure 7.7) revealed the ions resulting from the fragmentation of the glycoside in position 3. The same behavior is also observed in the case of kaempferol 3-sophorotrio-side-7-sophoroside (a pentaglycoside) (Ferreres et ah, 2004) in which... [Pg.235]

Fig. 4 Precursor ion scanning in a triple quadrupole instrument. Quadrupoles 1 and 3 behave as mass filters, scanning as shown in the lower part of the diagram. The instrument is analysing kaempferol-glucose, and the third quadrupole is set constantly to the mass of kaempferol. The first quadrupole scans. The spectrum resulting from this method shows any precursor ion that fragments to die mass of kaempferol... Fig. 4 Precursor ion scanning in a triple quadrupole instrument.
