Abstract:
Objective: To study the extraction preparation process of the crude drug Caulis spatholobi, using ethanol as the extraction solvent. Methods: Applying the countercurrent continued technique, using the L 9(34) orthogonal layout to optimize the preparation process as guided by the content of solid. After the optimize process was achieved, the extraction rate and the transfer rate of the effective components were tested by HPLC, using milletol as its marker and also the new preparation process was compared with the reflex process. Results: The transfer rate reached 84% or above, and the amount of the ethanol used was reduced by a half. Conclusion: The equipment is suitable for extracting the effective ingredients of crude drugs of ethanol used as extraction solvent, it is highly effective and can save energy sources alike.
