    AbstractRosa roxburghii Tratt is a traditional Chinese plant that has been used to treat different inflammatory diseases. The purpose of this study was to investigate the mechanism of action of Rosa roxburghii Tratt extract (RRTE) against ulcerative colitis (UC) using network pharmacology and experimental validation. HPLC-Q/Orbitrap MS was used to rapidly identify the substances contained in RRTE after extracting the active components from the fruit. Then, network pharmacology combined with molecular docking was used to explore the critical target and potential mechanism of RRTE against UC using the active ingredients in RRTE as the research object. Data are presented in a visual manner. Finally, the pharmacological effects of RRTE in alleviating UC were further verified using a DSS-induced UC model of NCM460. The results showed that 25 components in RRTE were identified. A total of 250 targets of the active components and 5376 targets associated with UC were collected. Furthermore, a systematic analysis of the Protein-Protein Interaction (PPI) networks suggests that epidermal growth factor receptor (EGFR), phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), and serine/threonine kinase 1 (AKT1) are critical targets for RRTE in the treatment of UC. A comprehensive regulatory network analysis showed that RRTE alleviated UC through the EGFR-mediated PI3K/Akt pathway, and molecular docking showed that active components could strongly bind to EGFR, PIK3R1, and AKT1. In addition, RRTE alleviated dextran sulfate sodium salt (DSS)-induced cell injury and significantly decreased the protein expression levels of EGFR, PIK3R1, and p-AKT in NCM460 cells in vitro. Furthermore, RRTE significantly regulated the expression of the apoptosis-related proteins Apoptotic protease-activating factor 1 (Apaf1), cleaved caspase-3, B-cell lymphoma-2 (Bcl2), and Bcl2 associated X protein (Bax). In conclusion, the components of RRTE are complex, and RRTE can relieve UC through the EGFR-mediated PI3K/Akt pathway.
