Rapid Identification and Analysis of Chemical Components in Heartwood of Dalbergia cochinchinensis by UPLC-Q-TOF-MS/MS
To rapidly identify and analysis the chemical constituents in the methanol extract of heartwood of
Dalbergia cochinchinensis
by ultra high performance liquid chromatography-quadrupole-time-of-flight high resolution mass spectrometry (UPLC-Q-TOF-MS/MS).
Method:
2
UPLC RRHD SB-C
18
column (3.0 mm×100 mm
1.8 μm) was used for chromatographic separation with acetonitrile-0.1% formic acid solution as the mobile phase for gradient elution (0-0.01 min
5%B; 0.01-2 min
5%-22%B; 2-28 min
22%-35%B; 28-45 min
35%-44%B; 45-55 min
44%-100%B; 55-57 min
100%B; 57-57.10 min
100%~5%B) at a flow rate of 0.3 mL·min
-1
. The analytes were determined in negative ion mode with electrospray ionization (ESI) and data collection range of
m
/
z
100-1 500.
Result:
2
A total of 101 chemical constituents were identified
including 22 flavonoids
34 isoflavones
15 neoflavonoids
18 other flavonoids and 12 other components.
Conclusion:
2
UPLC-Q-TOF-MS/MS technique can quickly
accurately and comprehensively identify the chemical constituents in the heartwood of
D
.
cochinchinensis
. Isoflavones
flavonoids and neoflavonoids are the main chemical constituents in the heartwood of
D
.
cochinchinensis
which is of great significance to reveal its internal material basis and provides experimental basis for this plant to be developed as a potential new resource of traditional Chinese medicine.
