According to UPLC-TOF-MS data analysis, the difference regarding the position and intensity regarding the peaks at 1713- 1707 cm-1 within the three samples were regarding the real difference in the relative content of tannin and pentacyclic triterpenoids. In second derivative infrared spectroscopy spectra, further analysis for the variations in the infrared spectra associated with the three samples had been perforponents were assigned, which somewhat e
