The macroporous resin separation technology has been mainly applied in the enrichment of saponins, flavonoids, alkaloids and other ingredients, and used in the removal of heavy metal impurities and pesticide residues in recent years. This paper focuses on the synthesis of the new-type macroporous adsorption resin LKS-11 according to the molecular structure characteristics of procymidone. Specifically, the selective absorptive property and other advantages of macroporous resin were utilized to analyze the procymidone removal efficiency in ginseng extracts from different sources. The type of macroporous resins, absorptive property and desorption conditions were observed respectively by static and dynamic adsorption methods to determined the optimum process conditions. According to the results, LKS-11 showed a good absorptive property to procymidone in ginseng extracts and provided a theoretical basis for studies on the removal of procymidone residues from ginseng extracts by using macroporous adsorption resin. Because of no secondary pollution on samples, low production and operation costs, high procymidone removal efficiency and high product recovery rate, this method is suitable to be applied in production.
