Abstract:
Objective To optimize the preparation process of Xiaochuan Tiegao. Methods The effective compound imporatorin of Dahurian Angelica Root was determined by HPLC. The best condition of preparation process for the ethanol-extraction method was investigated by L9(34) orthogonal design. Results The optimum technical condition:adding 2 times ethanol, cooking 1 hour and 2 times with 90% ethanol. Conclusion The method is reliable, accurate and easy to operate.
