Abstract:Objective To optimize the extraction process of Specnuezhenide in Jiawei Bazhen Mixture. Methods The orthogonal experiment method was used to determine the content of the Specnuezhenide in the extract as the index, and the immersion time (A), the water addition ratio (B), the extraction times (C) and the extraction time (D) as factors which affected the extraction effect of the decoction were studied. High performance liquid chromatography (HPLC) was used to determine the content of Specnuezhenide in Jiawei Bazhen Mixture. Results A2B1C2D1 was the best extraction process for Jiawei Bazhen Mixture, that was, adding 6 times of water, immersing for 1 hour, and boiling and extracting 3 times for 1 hour each time. Conclusion The preferred process for this experiment is to obtain the highest extraction rate of mixture and the highest extraction rate of Specnuezhenide.
