[Study on the chemical components of Rabdosia excisa]

Four kinds of components were extracted and separated from the stems and leaves of Rabdosia excisa. They had been identified as Kamebakaurin, Ursolic acid, Daucosterol and Liquiritin respectively by physical and chemical methods, as well as spectrum data. It was first time that Liquiritin was obtained from the Robdosia family, and its 13C-NMR data of Liquiritin had not been reported before.
