Objective: To optimize macroporous resin for purifying total flavonoids from Chrysanthemum morifolium and its technology conditions. Method: Using the content of total flavonoids as index which was determined by UV spectrophotometry

adsorption and desorption performance of HPD100

DM130

D101

AB-8 four macroporous resins for total flavonoids from C. morifolium were investigated

in order to screen optimum macroporous resin and optimize its separation technology conditions. Result: Adsorption capacity and desorption rate of AB-8 was the most in these resins

values were 44.9 mg·g-1 and 87.9%

respectively. Optimum separation technology was:the content of total flavonoids from sample solution 12.6 g·L-1

desorption time 1 h at 30 ℃

95% ethanol as eluent. Conclusion: AB-8 resin was suitable for adsorption and separation of total flavonoids from C. morifolium.
