摘　　要：对使用大孔树脂吸附提取玫瑰茄红色素的条件和方法进行研究。通过7种树脂对玫瑰茄红色素的吸附及不同洗脱剂的解吸比较表明:HPD-100树脂对该色素有较好的吸附性能,用90%的乙醇洗脱,使用20次后其吸附性能无明显减弱,可循环使用。Red pigments from Hibiscus sabdariffa L. were extracted with HCI solution （pH 3）, and then were separated from the extract with 7 macroporous resins. According to the adsorption efficiency to the red pigments, resin HPD-100 was selected for the further study concerning adsorption and desorption conditions for achieving the best separation effect of the red pigments. Results showed that the best adsorption efficiency was achieved when pH value of the extract was 3.0, at 40- 60℃ the HPD-100 exhibited the highest adsorption efficiency, and the time to reach adsorption equilibrium was 150 min with the adsorption efficiency of 96.90%; the best desorption effect of the red pigments was achieved by using 90% ethanol as the elution solvent. After being used repeatedly 20 times, the HPD-100 still had good adsorption capability.
