Abstract The aim of this study was to determine release rate and changes in polyphenols’ content, which were sorbed to carboxymethyl cellulose gel and subsequently desorbed. An aqueous extract of blue marc vine variety Fratava was used as a source of polyphenols. The gel was dried into a solid film and polyphenols were then desorbed again by dissolving this film in saline (isotonic) solution. Further, the influence of different times of high temperature (180°C) of drying gel on change in the amount of released polyphenols and also kinetics of their release in re-transfer of the film on the gel and solution was studied. The process simulates the possible use of carboxymethyl cellulose/ polyphenols film sorbed on textile materials and its contact with the tissues and body fluids such as course of wound healing.
