Objective:To establish purification technology of coumarin from Cortex Daphnes.Method: Investigated adsorption capacity of 3 kinds of macroporous resin with daphnetin and coumarins as indexes
and adsorption characteristics and elutive ratio of coumarin from Cortex Daphnes were studied systematically.Result: D-101 resin had a better purification performance to daphnetin and coumarins.Optimum conditions were as follows:concentration of durg 50 g·L-1 in terms of raw material
adsorption speed was 2 BV·h-1
pH of sample for loading 3.0.After eluted with 4 BV of distilled water
5 BV 50% ethanol was used with desorption speed was 2 BV·h-1.Conclusion: This process of applying macroporous resin to purify coumarin in Cortex Daphnes was reasonable and feasible.
