Chemical compound
Dactylifric acid (also known as dattelic acid or 5-O -caffeoylshikimic acid [ 2] [ 3] [ 4] ) is an ester derived from caffeic acid and shikimic acid . It and its isomers are enzymic browning substrates found in dates (Phoenix dactylifera fruits).[ 3] [ 5]
Some older sources identify dactylifric acid as 3-O -caffeoylshikimic acid.[ 5]
