Cleavage rules of mass spectrometry fragments and rapid identification of chemical components of Radix Paeoniae Alba using UHPLC‐Q‐TOF‐MS

In this study, we analysed the chemically active pharmaceutical ingredients and assessed the quality of RPA. In addition, we demonstrated that UHPLC-Q-TOF-MS can be used to qualitatively classify and identify the variety of chemical components of traditional Chinese medicines (TCMs) to a certain extent. Moreover, we confirmed that mass spectrometry can be used to identify the components of TCMs.
