Dynamic Absorption and Desorption Properties of HPD722 Macroporous Resin for Flavonoids in Emilia sonchifolia Extract

Abstract:

The impact of HPD722 macroporous resin on the dynamic adsorption and desorption of flavonoids in Emilia Sonchifolia extract is studied. The diameter-height ratio of macroporous resin column is 1:10; the mass concentration of the sample solution is selected to be 50.00 mg•mL-1; while the sample flow rate is 3.00mL min-1; upon dynamic absorption for once, the absorption rate reaches 81.11%; with adoption of 50mL ethanol at a volume ratio of 60% as the desorption agent, the desorption flow rate comes to 3.00mL•min-1; and the desorption rate of flavonoids attains 85.26%. Under optimal conditions, the content of flavonoids increases from 6.05% to 32.65% upon purification by HPD722 macroporous resin.
