Adsorption Performance of Polyamide Resin for Aloe Flavonoids

The best purification technology of the crude flavonoids from aloe leaf powder with polyamide resin was studied in this article.The optimum purification technique with polyamide resin was confirmed by studying the static and dynamic absorption under different conditions.The result showed that the adsorption were appropriate when the concentration of aloe crude flavonoids was 12 mg/mL and the flow rate was 2.0 mL/min at room temperature.When the ethanol concentration was 60%,the effect of elution was satisfactory.
