Study on purification of flavonoids from coriander with AB-8 macroporous resin

AB-8 macroporous resin was used to separate and purify coriander flavonoids, static and dynamic adsorption and desorption behaviors of AB-8 macroporous resin were evaluated for achieving the best purification of total flavonoids. The static: adsorption equilibrium time was 4 h,desorption time was 1. 5 h. The dynamic: the best adsorption was sample concentration of 1. 0 mg / mL,pH of 6. 0 and the flow rate of 2. 0 mL / min. The desorption flow rate of 2. 0 mL / min and 70% ethanol elution were the best. With definite technical process,the AB-8 macroporous resin could be used to purify the flavonoids of coriander.
