Abstract: Extraction conditions of zizyphus pigment were discussed and the optimum extraction conditions were determined by orthogonal test. The results of orthogonal test showed that the optimum extracting conditions were: temperature was under 80℃, ultrasonic extracting time 30 minutes and the proportion of materials 1:16.The effects of different conditions such as light, pH, H2O2 and Na2SO3 on the stability properties of pigment were also discussed.
