Analysis on Chemical Constituents in Xiao Chengqitang by UPLC-Q-Orbitrap-MS
To rapidly identify the chemical constituents in Xiao Chengqitang by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry (UPLC-Q-Orbitrap-MS).
Method
2
The method was established by the Waters CORTECS T3 column (2.1 mm×150 mm, 1.6 μm), mobile phase was methanol (A)-0.1% formic acid aqueous solution (B) for gradient elution (0-5 min, 3%-21%A; 5-20 min, 21%-36%A; 20-32 min, 36%-50%A; 32-42 min, 50%-62%A; 42-50 min, 62%-85%A; 50-60 min, 85%-95%A), the flow rate was 0.2 mL·min
-1
, and the column temperature was 30 ℃. UPLC-Q-Orbitrap-MS was operated in positive and negative ion modes, the scanning range was 100-1 200 with mode of Full MS/dd-MS
2
, and the collision energies were 20, 40 eV. The compounds were identified by comparing with reference substances and combining with literature reports and MS database information.
Result
2
A total of 123 components were identified in Xiao Chengqitang, including 33 flavonoids, 25 anthraquinones and anthrones, 23 phenylpropanoids, 15 tannins, 10 nitrogen-containing components and 17 other components. Among them, 32 components were determined by reference substances.
Conclusion
2
The material basis of Xiao Chengqitang is flavonoids, anthraquinones and anthrones, phenylpropanoids, which is derived from Aurantii Fructus Immaturus,
Rhei Radix et Rhizoma and Magnoliae Officinalis Cortex, respectively.
