4-O-β-D-Glucosides of Hydroxybenzoic and Hydroxycinnamic Acids — Their Synthesis and Determination in Berry Fruit and Vegetable

Schuster, Bernhard; Winter, Michael; Herrmann, Karl (Berlin : De Gruyter, 1986)

Protocatechuic acid-4-, gallic acid-4-, caffeic acid-4-, ferulic acid- and p-coumaric acid-O-β-D- were synthesized. These substances were characterized by UV, 1xgH NMR, 13C NMR and FAB-MS. Their proportions in berry fruit ...
