A strategy to comprehensively and quickly identify the chemical constituents in Wuteng tablets by ultra‐high‐performance liquid chromatography coupled to quadrupole time‐of‐flight mass spectrometry

Population growth and improved industrialization have led to a sharp rise in the demand for plant medicine. In recent years, there has been a general concern about developing new medicinal resources, cutting down on pharmaceutical waste, and discovering new, effective components of traditional Chinese medicine. A novel medication called Wuteng tablets is made from Schisandra chinensis stems and shows promise as a treatment for Alzheimer's disease. This work is the first development of an overall identification technique based on ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC-Q/TOF-MS). Using the MS-DIAL integrated informatics platform and UNIFI software, the chemical components of Wuteng tablets were identified, and the amount of lignin in the tablets was ascertained. This study will identify the chemical components of such medications, aid in the development and utilization of medicinal plant resources, and serve as a foundation for the analysis of the components of their biopharmaceutical origin.
