| Abstract: | In this article, HPLC with a photodiode array detector was used to record the UV spectra of the ursolic acid. The analysis method of chromatogram peak has been established. Fourier transform-infrared spectroscopy (FTIR) was used to record the IR spectra of the ursolic acid and get the IR spectral characteristics of the ursolic acid. The relationship of the wave peaks of IR spectra and the structural characteristics was analyzed. The attribution of the functional groups in the structural characteristics of ursolic acid was basically defined. The peaks in the IR spectra are clear and distinguishable and are used to assign the functional groups easily. Using with mass spectrum together, molecule framework, position of functional groups and structure of ursolic acid is concluded. |
