Chemical Constituent Analysis of Tongxie Yaofang Decoction by UPLC-LTQ-Orbitrap-MS增强出版
To rapidly identify the chemical constituents in Tongxie Yaofang decoction by ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-LTQ-Orbitrap-MS).
Method
2
Chromatographic conditions were ACQUITY UPLC BEH C
, column temperature at 35 ℃ and injection volume of 3 μL. UPLC-LTQ-Orbitrap-MS was equipped with an electrospray ionization(ESI), the MS and MS/MS data were collected in positive and negative ion modes, and detection range was
m
/
z
100-1 250. Combining the reference substance, chemical databases and related literature information, TraceFinder 4.1 and Xcalibur 2.1 were used to identify the chemical constituents of Tongxie Yaofang decoction.
Result
2
A total of 90 compounds, mainly including flavonoids, coumarins, monoterpene glycosides, chromones and lactones, were identified from Tongxie Yaofang decoction. By attributing the sources of Chinese medicines for all identified compounds, 9 of them were found to be derived from Atractylodis Macrocephalae Rhizoma, 21 from Paeoniae Radix Alba, 24 from Citri Reticulatae Pericarpium, 29 from Saposhnikoviae Radix, and 7 from at least two Chinese medicines.
Conclusion
2
The method can effectively, quickly and comprehensively identify the chemical components of Tongxie Yaofang decoction, and clarify the chemical composition. These identified compounds cover the main active ingredients of the four herbs with high abundance, which indicates that the extraction method and the ratio of the medicinal materials of Tongxie Yaofang are scientific, and can provide a reference for the research on the material basis and quality evaluation of this famous classical formula.
