Rapid Identification on Chemical Components in Dalbergiae Odoriferae Lignum by UPLC-Q-TOF-MS/MS
Dalbergiae Odoriferae Lignum is a rare traditional Chinese medicine material in China. However
there are many varieties of various sources and different qualities in the market at present. In order to further define the pharmacodynamic substance basis
electrospray time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS/MS) was used to rapidly analyze chemical constituents of methanol extract of Dalbergiae Odoriferae Lignum.
Method:
2
Chromatographic separation was performed on an UPLC RRHD SB-C
18
(3.0 mm×100 mm
1.8 μm)for gradient elution
with mixtures of acetonitrile and 0.1%formic acid-water as mobile phases at a flow rate of 0.3 mL·min
-1
. The column temperature was maintained at 40 ℃. The data was collected in a negative ion mode with electro-spray ionization source(ESI).
Result:
2
According to molecular ion peaks and MS
2
mass spectrometry characteristic fragment ions
Mass Bank databases
as well as the mass spectrometry information of reference substances and relevant literatures
a total of 83 constituents were identified
including 18 flavones
31 isoflavones
10 neoflavonoids
9 isoflavanones
7 other flavonoids and 8 other components.
Conclusion:
2
UPLC-Q-TOF-MS/MS can quickly
accurately and comprehensively identify chemical constituents in methanol extract of Dalbergiae Odoriferae Lignum
and isoflavones
flavones
neoflavonoids and isoflavanones are the main chemical constituents
which laid a foundation for the basic research of medicinal substances of Dalbergiae Odoriferae Lignum
and provided theoretical basis and technical support for the improvement of quality standards of Dalbergiae Odoriferae Lignum.
