Optimization of Extraction Technology for Zhichan Decoction by Orthogonal Test

Yi Feng

Abstract

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.
