[Evaluation of AB-8 macroporous adsorption resin for adsorption of total flavones in liquorice].
OBJECTIVE
To evaluate the performance of AB-8 macroporous adsorption resin for adsorption and desorption of flavones in liquorice.


METHODS
The 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.


RESULTS
Optimal 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.


CONCLUSIONS
AB-8 macroporous adsorption resin can be well applicable for enrichment of flavones in liquorice.
