Simultaneous Determination of Four Alkaloid Components in Xiangbin Decoction by UPLC-QqQ-MS/MS
To establish a quantitative method for the simultaneous determination of arecaine
arecoline
norisoboldine and boldine in Xiangbin decoction by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-QqQ-MS/MS)
and compare the variation of their contents between single and mixed decoctions.
Method:
2
The separation was carried on a Waters ACQUITY UPLC BEH Shield RP18(2.1 mm×150 mm
1.7 μm)column
with 0.1%formic acid solution-acetonitrile as mobile phase for gradient elution. The flow rate was 0.2 mL·min
-1
and the column temperature was 30 ℃. The quantitative MRM transitions of the four components were
m
/
z
142.10/44.11 for arecaine
m

z
156.20/44.07 for arecoline
m

z
314.29/265.12 for norisoboldine and
m

z
328.13/265.10 for boldine. The determination was performed in multiple reaction monitoring (MRM) mode by mass spectrometry with electrospray ionization (ESI) source under positive mode.
Result:
2
The linear ranges of arecaine
arecoline
norisoboldine and boldine were 0.479 0-57.48
0.976 0-78.08
0.812 0-64.96
0.091 2-18.24 μg·L
-1
respectively. The average recoveries of the above compounds ranged from 93.73%to 104.34%
with RSD (
n
=6) of less than 5%. The contents of arecoline
arecoline
norbibeldine and boltinine in Xiangbin decoction were (90.07±1.26)
(445.27±12.39)
(742.35±38.39)
(38.50±3.33) μg·g
-1
which were significantly lower than the contents in Linderae Radix and Arecae Semen.
Conclusion:
2
The method is rapid
sensitive
accurate and reproducible
and suitable for the simultaneous determination of multiple components in Xiangbin decoction
so as to provide a basis for the quality control of Xiangbin decoction. The compatibility of Xiangbin decoction has a significant effect on the dissolution contents of arecaine
