Objective: To optimize extraction technology of compound Zhichan decoction. Method: With the content of rhynchophylline
isorhynchophylline
paeoniflorin as index
which were determined by HPLC
effects of the amount of water
extraction time
extraction times on extraction technology was investigated by L9(34) orthogonal test. Result: Optimal extraction technology conditions were as followings:extracted 2 times with 10 folds the amount of water
1 h per time. Conclusion: This optimized extraction technology was stable and feasible with high extraction rate.
