Identification of Chemical Constituents in Bufei Jianpi Formula by UPLC-Q-TOF-MS/MS
To identify and analyze the chemical constituents in Bufei Jianpi formula by UPLC-Q-TOF-MS/MS.
Method:
2
An Agilent Poroshell SB-C
18
column (4.6 mm×100 mm
2.7 μm) was used with a mobile phase system of 0.1% formic acid solution (A)-acetonitrile (B) for gradient elution (0-10 min
3%B; 10-100 min
3%-50%B; 100-120 min
50%-100%B) under positive ion mode and water (A)-acetonitrile (B) for gradient elution (0-5 min
3%B; 5-60 min
3%-100%B) under negative ion mode
the flow rate was 0.6 mL·min
-1
and the column temperature was 30 ℃. Mass spectrometric data were obtained under electrospray inoization (ESI) in positive and negative ion modes
the collection range was
m
/
z
50-1 000.Agilent MassHunter Qualitative Analysis software was used to extract and match chromatographic peaks.
Result:
2
Combined with reference
related literature and database analysis
95 compounds were identified by mass spectrometry information
including 41 flavonoids
23 alkaloids
12 lignans
9 organic acids
and 10 other compounds.
Conclusion:
2
The chemical composition of Bufei Jianpi formula is complex
and the cracking rules of different components are different. Flavonoids are prone to deglycosylation
dehydration
Diels-Alder reaction (RDA) cleavage of the ring during lysis
and loss of some neutral molecules such as CO
CO
2
CHO. Lignans has a substituent such as a hydroxyl group
a carbonyl group or a methoxy group on the benzene ring
and it is easy to obtain a fragment ion which loses H
2
O or CO. The basic structure of organic acids is a phenolic hydroxyl group-substituted aromatic ring
acrylic acid
fatty acid or the like
this kind of compound is easy to lose H
2
O and COOH in negative ion mode
and it is easy to break at the carbonyl to form fragment ions. This established method is rapid
sensitive and accurate
which can quickly identify the chemical constituents in Bufei Jianpi formula and provide evidences for clarifying efficacy material base of this formula.
