Abstract:
OBJECTIVETo evaluate the performance of AB-8 macroporous adsorption resin for adsorption and desorption of flavones in liquorice.
METHODSThe concentration of flavones in liquorice was determined by ultraviolet spectrophotometry, and the adsorption behavior of AB-8 macroporous adsorption resin to flavones in liquorice was examined for the adsorption capacity and the volume of solution loaded.
RESULTSOptimal adsorption of flavones was achieved with the sample pH of 5, total flavones concentration in the solution of 0.85 mg/ml, sample flow velocity of 3 BV/h, and washing with 60% ethanol at the flow velocity of 3 BV/h.
CONCLUSIONAB-8 macroporous adsorption resin can be well applicable for enrichment of flavones in liquorice.
