Objective: To optimize extraction process conditions of Xiaoer Pingchuan Qutan granule. Method: Using extraction amount of ephedrine hydrochloride
pseudoephedrine hydrochloride
hesperidin and yield of dry extract as indexes
HPLC was used to quantitative analysis
water extraction technology of Xiaoer Pingchuan Qutan granule was optimized by L9(34) orthogoral design. Result: Optimum water extraction technology was as follows: extracted 3 times with 10
8
8 times the amount of water
extracted 1.5
1
1 h in turn. Conclusion: This optimized extraction technology was stable and feasible
it could be used in industrial production of Xiaoer Pingchuan Qutan granule.
