Research Progress on Extraction Process of Ursolic Acid from Fructus Corni

The research progress of extraction methods of ursolic acid from fructus corni are summarized and supercritical extraction method is compared with traditional solvent method. The results indicate that, in the premise of the same yield of ursolic acid, supercritical carbon dioxide extraction not only can realize the clean production, but also is easy to industrialization. So, it is an extraction method with good prospect of application.
