The results showed that HPD-100 resin had the best performance of absorbing the red pigment ofMynica rubra Sied et Zucc. In the course of desorbing the absorbed pigment 80% ethanol was optimal, HPD-100 resin wasselected during the experiment. After repeating 20 times, the absorption factor was only at a loss of 3.86%.
