Dynamic Absorption and Desorption Research of HPD722 Macroporous Resin for Flavonoids in Thlaspi arvense Linn Extract

Abstract:

The impact of HPD722 macroporous resin on the dynamic adsorption and desorption of flavonoids in Thlaspi arvense Linn extract is studied. Obtained optimal conditions：the mass concentration of the sample solution is selected to be 4 mg•mL-1; while the flow rate of sampling is 1.30mL min-1; pH value is 4；50mL ethanol at a volume ratio of 70% is adopted as the desorption agent；the desorption flow rate reaches 3.47 mL•min-1. Under these conditions, the content of flavonoids increases from 5.09% to 21.91% upon purification by HPD722 macroporous resin.
