Optimization of Extraction Process for Sanren Tongbian Mixture by Orthogonal Test / 中国药师

Objective:To optimize the extraction technology for Sanren Tongbian mixture. Methods:The water amount,decoction time and decoction frequency as the evaluation factors,and the content of amygdalin and the paste-forming rate as the evaluation indi-ces,the extraction process of Sanren Tongbian mixture was optimized by L9 (34 ) orthogonal design. Results: The optimal extraction conditions were as follows:adding 8-fold amount of water, decocting twice with 1. 5h for each time. Conclusion: The study provides scientific basis for the research of the extraction technology of Sanren Tongbian mixture, and the further experiments proved that the op-timized process is stable and feasible.
