Abstract:Objective: To search for the method used in refining Xiaoyao Pill by macroporous adsorption resin, 12 types of macroporous adsorption resin were optimized. Method: Static and dynamic adsorption test and de-adsorption test were carried out to screen the best macroporous resin. The single factor test was applied to optimize the manipulation parameters of macroporous resin. Result: The macroporous resin D-101-1 possessed the strongest adsorption ability, in addition to an easy de-adsorption property. Conclusion: The D-101-1 type macroporous adsorption resin shows better comprehensive adsorption property. It is available for the refine Xiaoyao Pill.
