Objective:To study the optimum conditions for the purification of salvianolic acid by macro-porous resins.Method:The macroporous resin was selected and the purification process was evaluated by measuring the content of salvianolic acid B.Result:The HPD-300 maoroporous resin was the most effective one among the resins.The optimum conditions were screened
the adsorption capacity of HPD-300 macroporous resin was 172.4 mg/g
pH was 3.5;and the volume of 70% ethanol as eluent was 3 BV.By this method
the yield of salvianolic acid B was 88.11%;and the purity was 72.80%.Conclusion:The method is effective for purification of salvian-olic acid.
