In recent years, direct and indirect evidence has been found of the efficacy of the traditional Chinese medicine Bergenia purpurascens in treating arthritis and osteoarthritis. Several major components, such as bergenin and 11‐O‐galloylbergenin, have good anti‐inflammatory activity. Since research on the chemical components of Bergenia purpurascens and related mechanisms for the treatment of osteoarthritis has never been performed, this study aimed to analyze the chemical components of Bergenia purpurascens through ultra high performance liquid chromatography coupled with quadrupole time‐of‐flight mass spectrometry technology and the UNIFI screening platform to predict the underlying mechanisms in treating osteoarthritis by analyzing the network pharmacology. In total, 43 chemical constituents were identified, mainly flavonoids (18), phenolic glycosides (13), and organic acids (7). Among them, 16 components were found in Bergenia purpurascens for the first time. Through the analysis of network pharmacology, several potential candidate targets and pathways were initially predicted, including AKT1, MAPK1, and MAPK3, as well as the apoptosis, estrogen, and MAPK signaling pathways. Bergenin, 11‐O‐galloylbergenin, arbutin, catechin‐3‐O‐gallate, and other components play a synergistic role in treating osteoarthritis. This study analyzed the chemical components of Bergenia purpurascens and preliminarily revealed potential mechanisms of treating osteoarthritis, providing a basis for further evaluating the drug's efficacy.
