Identification of in Vitro and in vivo Chemical Constituents of Ruyi Zhenbaowan Based on UHPLC-Q Exactive Orbitrap HRMS增强出版
The chemical constituents of Ruyi Zhenbaowan were identified based on UHPLC-Q Exactive Orbitrap HRMS. A total of 12 male SD rats were randomized into two groups: control (pure water) and Ruyi Zhenbaowan (1.8 g·kg
-1
). The rats were administrated with the suspension of Ruyi Zhenbaowan or pure water by gavage. After 1.5 h, the plasma and cerebrospinal fluid were collected. Chromatographic separation was performed on a Waters ACQUITY UPLC BEH C

column (2.1 mm × 150 mm, 1.7 μm) with a mixture of 0.1% formic acid aqueous solution (A) and acetonitrile (B) as the mobile phase. Gradient elution was carried out according to the procedure of 0~15 min,97%~80%A;15~30 min ,80%~60%A;30~40 min,60%~30%A;40~45 min,30%~5%A. The ion source was electrospray ionization, and scan range was

100-1 500. The prototype components and the components in the plasma and cerebrospinal fluid were analyzed qualitatively by scanning in positive and negative ion modes and identified by comparison with the data in published literature and the information of standard substances.
Result

A total of 126 chemical constituents were identified from the 80% methanol solution of Ruyi Zhenbaowan, and 14 and 7 prototype constituents were detected in the plasma and the cerebrospinal fluid, respectively. In addition, the fragmentation rules of apigenin, apigenin-7-
O
-glucuronide, galangin, liquiritin, piperine, glycyrrhizic acid, eugenol, gallic acid, and cholic acid were deduced.
Conclusion
