[Abstract] Objective: To optimize the ultrasound extraction process of crude polycose in Polyporus umbellatus (Pers.) Fries. Methods: Using the content of polycose detected by the phenol-sulphuric acid method as the index to study the best extraction process. Results: The best process was that extracting for 3 timesusing 14 times water,and 20 min for each time ......
