Dactylifric acid explained

Dactylifric acid (also known as dattelic acid or 5-O-caffeoylshikimic acid^{[1] [2] [3]}) is an ester derived from caffeic acid and shikimic acid. It and its isomers are enzymic browning substrates found in dates (Phoenix dactylifera fruits).^{[2] [4]}

Some older sources identify dactylifric acid as 3-O-caffeoylshikimic acid.^[4]
