Abstract:Objective: To screen optimum the extraction process of ursolic acid from Potentilla discolor Bge. Methods: ultrasonics extraction was used to extract. The optimum extraction process was confimed by the orthogonal test. The content of ursolic acid in Potentilla discolor Bge. was determined by HPLC. Results: The optimum conditions of ultrasonics extraction are as follow: ethanol concentration 75%, time 60 min, ratio of material to solution 1:60, and power of extraction 610 W. The effects of factors on yield decrease progressively in the following order: extracting time>ratio of material to solution>ethanol concentration>power of extraction. Conclusion: The best optimized process has a good repeatability confimatory experiment.
Keywords:Potentilla discolor Bge    ursolic acid  extraction
