Popis: Ding-Zhi-Xiao-Wan (DZXW) is a traditional Chinese medicine widely used for treating depression. To clarify the bioactive constituents of DZXW, a new rapid ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS(E)) method was established in this study, with the whole extract of the formula separated into multiple components to facilitate the analytical process. In total, 97 compounds were detected and 88 were identified in DZXW. Based on their exact masses, fragmentation characteristics, and retention times, 85 of the 88 compounds were confirmed either conclusively or tentatively, and three potentially novel compounds were identified. In addition, following a three-day oral administration of DZXW, 60 and 28 compounds were observed in the plasma of normal and depressive rats, respectively. Finally, by combining our data with pharmacological information, 10 compounds were predicted as the likely bioactive constituents of DZXW as an antidepressant agent. Our approach provided a rapid method for characterising the chemical constituents of DZXW, and we were the first to screen for bioactive indexes in the plasma of depressive rats. Furthermore, our results provide useful chemical information that could be employed for further study of the pharmacodynamic material basis of DZXW's antidepressant effects.
