Studied adsorption and desorption conditions of AB-8 type macroporous resin to black wheat bran pigment,and HPLC were applied to identify the purified pigments.It was found that the absorption and desorption equilibrium time of black wheat bran in AB-8 type macroporous resin was 26 h and 7h.The affect of pH to macroporous resin adsorption rate is not significant.70% ethanol solution(pH=1.0) was used to desorption pigment.In this condition,the AB-8 macroporous resin maximum adsorption rate is 83.00% and the maximum desorption rate is 85.53%.Four main anthocyanins component was found in purified pigments.
