| 摘 要： | 通过L9(34)正交实验优化金樱子棕色素的浸提工艺,并采用超滤膜和大孔吸附树脂进行分离和精制。研究结果表明,最佳浸提工艺为:浸提温度70℃,乙醇浓度60%,提取时间2h,料液比1∶6。AB-8为色素分离纯化的最佳吸附树脂,最佳吸附条件为:pH4.0,吸附流速2.5mL/min,吸附时间2h;最优洗脱条件为:70%乙醇、洗脱流速1.5mL/min,洗脱时间10～20min。经超滤和大孔吸附树脂吸附后,色素色价比未精制的高6.3倍。

| Abstract: | The extraction technology of pigment from Rosa laevigata Michx was optimized by L_9 (3~4) orthogonal test,and the use of ultrafiltration membranes and macroporous resin for separation and purification. The results showed that the optimal technological conditions were as follows:extraction temperature 70℃, at the condition of 60% ethanol solution as solvent, extraction time was 2h, the ratio of solid-liquid was 1:6.AB-8 for the pigment separation and purification was the best adsorption resin.The optimum conditions of adsorption were: pH 4.0,2h and adsorption rate was 2.5mL/min; the optimum conditions of desorption were, concentration of material liquid 70%,10～20min and adsorption rate was 1.5mL/min.The refined pigment's color number enhanced nearly 6.3 times. |
