Objective: To optimize extraction technology of Cynanchum paniculatum in Zhenggu mixtures. Method: With the content of paeonol as index
which was determined by HPLC
effect of grinding degree
ethanol concentration and extraction time on extraction technology was investigated by orthogonal test. Result: Optimum extraction technology conditions were as follows:grinding degree of raw material 20 mesh
maceration extracted 60 h with 70% ethanol
yield of paeonol 5.34 mg·g-1. Conclusion: Optimized technology was stable and feasible
this study could provide a reference for industrial production of Zhenggu mixtures.
