    Fragmentation of flavonoid compounds using soft ionization mass spectrometry
    Okao, Immaculate; Nagy, Lajos; DE--Természettudományi és Technológiai Kar--Kémiai Intézet
    Using ESI-MSMS-TOF, six compounds were fragmented under negative and positive ion modes. Compounds: (1), (5) and (6) were of similar fragmentation hence therefore only compound (1) was discussed. The compound (1) was first checked with an MS spectrum to see if it was suitable to use for the identification of fragments. The technique was based totally on the strategies of tandem mass spectrometry; the precursor turned into fragmented once more to supply the daughter peaks
