Optimization of Extraction Process of Yazhoukang Capsule by Orthogonal Experiment / 中国中医药信息杂志

Objective To optimize the preparing procedures of water extraction and alcohol precipitation of Yazhoukang Capsule. Methods The ratio of dry extraction and the content of paeoniflorin were used as indexes, orthogonal test was used for studying the influence on the process of four factors including decocting times, amount of water, decocting times, precipitating concentration of alcohol. Results The optimized preparation conditions were added 16 times water, decocting for 3 times, 1 h for each time and alcohol concentration of 40%. Conclusion The established method is suitable for extracting Yazhoukang Capsules preparation.
