Abstract：Objective: To establish the optimal ultrasonic procedure for extracting polysaccharides from Caulophyllum robusutm Maxim. Methods: The optimal conditions of extraction process for polysaccharides from Caulophyllum robusutm Maxim. were selected by evaluating the extractive yield of polysaccharides as marks by or-thogonal experimental design, investigating the ratio of solid to liquid, and extracting temperature, time and power. Results: The most important factors were the ratio of solid to liquid and extracting power. The optimal procedure was that Caulophyllum robusutm Maxim. was extracted with ultrasonic technology at solid-liquid ration of 1 : 20, ex-tracting power of 70 W, extracting temperature of 65 ℃ and extracting time of 70min. Conclusion: The optimal procedure for extracting polysaceharides from Caulophyllum robusutm Maxim. is simple, accurate and highly effi-cient with the polysaccharides yield of 13.67%.
