A procedure is presented for identification of cranberry hydroxycinnamic acids. Individual compounds were purified and identifications accomplished by using a variety of analytical techniques such as UV spectroscopy, colorimetric tests, paper chromatography, P‐glucosidase hydrolysis and high performance liquid chromatography. The identified compounds include glucose derivatives of p‐coumaric, caffeic, ferulic and sinapic acids. The absence of hydroxycinnamic acid‐quinic acid esters in cranberries has been substantiated.
