| Abstract: | Objective: To study the ultrasonic extraction process of Herba Plantaginis. Methods: The orthogonal test was used to determine the content of ursolic acid by HPLC. Result: The best cxtracting process is A 3B 2C 2, i.e, ultrasonic extracting twice by using ten times of EtoH (95%) with thirty minutes once. Conclusion: The ultrasonic extraction method has advantages speedy in extraction, needless in heating, shorter in time, and more important, more effective composition can be yielded. |
