Analysis of Chemical Constituents in Baihe Dihuangtang by UPLC-Q-TOF-MS
To study the chemical constituents in Baihe Dihuangtang by ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-Q-TOF-MS).
Method:
2
The separation was performed on an ACQUITY UPLC BEH C
18
column (2.1 mm×50 mm
1.7 μm) by a gradient elution of acetonitrile-0.1%formic acid solution. The flow rate was 0.4 mL·min
-1
and the column temperature was 30 ℃
the injection volume was 5 μL. Electrospray ionization was applied and the data were collected via positive and negative ion modes. By using SCIEX OS 1.4 software
the chemical constituents were analyzed based on the retention time
excimer ion peak and fragment ion peak of the compounds
as well as comparison with reference substances and literature data.
Result:
2
A total of 49 chemical constituents in Baihe Dihuangtang were identified
including 5 phenolic glycerides
15 phenylethanoid glycosides
11 iridoids
8 lonones
3 phenylpropanoids
2 nucleosides
1 organic acid
and 4 other compounds. Among them
phenolic glycerides belonged to Lilii Bulbus
and other components mainly belonged to Rehmanniae Radix. Four chemical constituents (acteoside
isoacteoside
ferulic acid and caffeic acid) were identified by comparison of reference substances.
Conclusion:
2
The established detection method can quickly and accurately analyze the chemical constituents of Baihe Dihuangtang. The information of chemical constituents in Baihe Dihuangtang is comprehensively expounded. The study establishes a foundation for the research of quality control
material foundation of efficacy and the development of compound preparations of Baihe Dihuangtang.
