Research on Adsorption of Total Paeony Glycoside with Macroporous Resins

OBJECTIVE To investigate the adsorption of total paeony glycoside by D101, X-5, HPD-722, HP-20, AB-8, DM-130, HPD-600, NKA-9. METHODS Through static adsorption and desorption as well as dynamic adsorption and desorption, the purification of total paeony glycoside by AB-8 macroporous resin was selected with paeoniflorin and albiflorin as investigation targets. RESULTS The adsorption quantity of AB-8 resin for paeoniflorin and albiflorin was 42.23, 53.70 mg·mL^-1, and desorption quantity was 32.19, 33.75 mg·mL^-1. CONCLUSION The isolation and purification capability of AB-8 macroporous resin is the best in the eight kinds of macroporous resins and have a favourable application perspective.
