Objective ： To establish the optimal extraction process of Yishenkang granule. Method ： Based on orthogonal experiment, according to the yield rate and content of paeoniflorin, analysis on influencing factors was made to select the best extraction process of water extraction and ethanol extraction. Results ： The best water extraction process was extracted by water for three times and adding 8 times water, 1.5 hour for each boiling time ; the best ethanol extraction process was extracted by 75 % ethanol two times, eight times ethanol, 1.5 hour for each time. Conclusion ： Stability and repeatability of extraction process are good, and can be applicable to large - scale production.
