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]
