Objective: To optimize purification technology of extracts from L. japonicae and F. suspensa in Shuanghuanglian by AB-8 macroporous resin. Method: The content of total phenolic and total flavonoids were used as indexes.Purification technology was optimized from proportion of diameter-height
adsorption concentration
adsorption speed and eluent concentration
etc. Result: Optimum purification technology was as follows: extracts of L. japonicae and F. suspensa were diluted to concentration was 1.5 g·mL-1by water
ratio of diameter-height 1∶10
proportion of maximum adsorption to resin volume was 1∶3.3
eluted by 3 BV of water
4 BV 70% ethanol as the eluent. Conclusion: This process of purification technology was stable and feasible.
