    Notes: Hydroxycinnamic acid derivatives have been shown to be a complex mixture of closely related compounds. A procedure has been described for their isolation and purification from cranberries. The hydroxycinnamates were extracted from the plant tissue with aqueous alcohol, followed by pre-separation on a polyamide CC-6 column. For easier sample concentration, the eluted compounds were extracted in alcohol. Final separations were made on a High Performance Liquid Chromatograph. Recycling was used to purify the individual compounds. A total of 15 compounds was purified. The method can be used for the separation and purification of individual phenollc compounds from mixtures.

    Identification of the Hydroxycinnamtic Acid Derivatives in Cranberries (1982)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: 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.
