Objective:To optimize extraction technology of compound preparation of Periploca forrestil. Method: Orthogonal design was used to investigate effect of solid-liquid ratio
ethanol concentration
extraction time and times on extraction technology of compound preparation of P. forrestil with composite score of total alkaloids yield and dry extract rate as index. Result: The best extraction conditions were as followings:extracted 3 times with 6-fold 70% ethanol
1 hour for each time. Conclusion: This optimized extraction technology was stable and feasible for preparing new formulation of extraction technology of compound P. forrestil.
