The characteristic of absorption and separation of five kinds of macroporous resins to extract total flavonoids of Chinese Winter Jujube(CWJ) was studied. Suitable resin for purification of total flavonoids was screened from five resins, and its characteristic of absorption and separation was investigated. The results showed that X-5 macroporous resins had better adsorbing and separating property for purification of total flavonoids from Chinese Winter Jujube. The optimum absorption conditions were that the...
