Simultaneous determination of 8 components in Jinqi jiangtang tablets by ion mobility mass spectrometry method
To establish the ion mobility mass spectrometry method for simultaneous determination of epiberberine, berberine, coptisine, palmatine, calycosin-7-glucoside, 3,5-
O
-dicaffeoylquinic acid, 4,5-
O
-dicaffeoylquinic acid and chlorogenic acid in Jinqi jiangtang table
ts.
METHODS
2
Ion mobility mass spectrometry method was used. The determination was performed on Waters ACQUITY UPLC HSS T3 (2.1 mm×50 mm, 1.8 μm) with mobile phase consisted of 0.1% formic acid solution-acetonitrile (gradient elution) at the flow rate of 0.3 mL/min. The column temperature was 40 ℃, and the injection volume was 5 μL. The contents of 8 components in Jinqi jiangtang tablets were determined by scanning detection under positive and negative ion modes with an electric spray ion source, and setting ion mobility mass parameters according to the peak response of each component.
RESULTS
2
The results showed that the linear relationship of the eight components was good within their respective ranges (
r
≥0.999); RSDs of precision, repeatability and stability (24 h) tests were not more than 4.0%; average recoveries were 94.6%-101.2% , RSDs were 2.6%-3.9% (
n
=9). The contents of the above eight components in three batches of Jinqi jiangtang tablets were 3.060-3.545, 24.50-26.74, 2.795-4.149, 1.437-2.501, 0.204-0.242, 0.950-1.281, 2.272-2.828, 7.314-7.960 mg/g, respectively.
CONCLUSIONS
2
The established method has high sensitivity and good reproducibility, and can provide reference for the quality control of the preparation.
