Study on Absorption and Separation of Flavonoids from Lotus Seed Pod by Macroporous Resin

Hongmei Chen

Abstract

8 types of macroporous resin were selected to compare the absorption rate and desorption rate for flavnoids from lotus seed pod.On the basis of static adsorption experiments,the macroporous resin AB-8 was chosen to test dynamic adsorption.The optimum conditions were as follows: sample concentration was 1.5mg·mL-1,sample rate was 3BV·h-1,pH value was 3.5,eluent alcohol concentration was 70%,flow rate was 2BV·h-1.
