[Separation and refine of Xiaoyao Pill by macroporous adsorption resin].

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.
