Molecules, Vol. 27, Pages 6639: Qualitative Analysis of Multiple Phytochemical Compounds in Tojapride Based on UHPLC Q-Exactive Orbitrap Mass Spectrometry Molecules doi: 10.3390/molecules27196639 Authors: Liying Zhang Shihan Qin Sunv Tang Shuai E Kailin Li Jing Li Wei Cai Lei Sun Hui Li Tojapride is composed of Caulis Perillae, Rhizoma Cyperi, Radix Glycyrrhizae, Citrus aurantium L., Coptis chinensis Franch, Pericarpium Citri Reticulatae, Reynoutria japonica Houtt, Tetradium ruticarpum, and Cleistocactus sepium. It has the effects of inhibiting gastric acid and relieving pain. It is clinically used for treating gastroesophageal reflux disease. To further study the pharmacodynamic properties of Tojapride, the systematic characterization of the chemical constituents in Tojapride was investigated using ultra-performance liquid chromatography with Q-Exactive Orbitrap mass spectrometry combined with parallel reaction monitoring for the first time. Eventually, a total of 222 compounds, including flavonoids, alkaloids, and glycyrrhizic acid derivatives, were identified based on the chromatographic retention times, MS/MS2 information, and bibliography data; a total of 218 of these were reported for the first time as being present in Tojapride. This newly developed approach provides a powerful tool for extending our understanding of chemical constituents of Tojapride, which can be further extended to other TCMP composition research.
