Fig. 2From: Highlighting mass spectrometric fragmentation differences and similarities between hydroxycinnamoyl-quinic acids and hydroxycinnamoyl-isocitric acidsTypical MS fragmentation patterns of HCAs conjugated to quinic acid (a–c) extacted from M. oleifera or isocitric acid (d–f) extracted from M. viridis: a 4-caffeoyl-quinic acid, b 4-p-coumaroyl-quinic acid, c 4-feruloyl-quinic acid, d 2-caffeoyl-isocitric acid, e 2-p-coumaroyl-isocitric acid and f 2-feruloyl-isocitric acidBack to article page
