Abstract: Cellulase was used to extract anthocyanins in wild Vaccinium uliginosum L. from Changpbai Mountain area, and then the ratio of solid to liquid, the amount of Cellulase, the temperature, the pH and the time of enzymolysis were investigated emphatically. Through single factors and L16(44) orthogonal design on the extraction process, the optimal parameters were obtained as follows: the ratio of solid to liquid 1:50, pH 1.5, the amount of Cellulase 2%, temperature 60 ℃ and time of enzymolysis 1 h. Based on the above conditions, the extraction rate was 6.105%.

Key words: Vaccinium uliginosum L., cellulase, anthocyanins
