【Abstract】 Objective To optimize the best extraction process of xiaoerzhixie granules. Methods Effects of watering volume, cooking time and cooking frequency on extraction were investigated through L9(34) orthogonal design by using Herba euphorbiae humifusae’s gallic acid as appraising index. Results The optimum extraction process was determined as adding 10 times amount of water,cooking 3 times and 2 hours each. Conclusion The process is stable and productive.更多还原
