HPLC Determination of Four Flavonoids of Aurantii Fructus Immaturus in Niuhuang Qingwei Pills and Genetic Analysis of Medicinal Materials
To establish an high performance liquid chromatography (HPLC) method for the simultaneous determination of four constituents in Niuhuang Qingwei pill (narirutin
naringin
hesperidin
and neohesperidin)
and identify the source of Fructus Aurantii Immaturus.
Method:
2
The analysis was performed on a Waters CORTECS C
18
column (4.6 mm×50 mm
2.7 μm)
with acetonitrile-0.12% formic acid solution as the mobile phase for gradient elution. The flow rate was 0.5 mL·min
-1
the detection wavelength was set at 283 nm
and the column temperature was 27 ℃.
Result:
2
12 batches of Niuhuang Qingwei pills showed the different content of flavonoids as
Citrus aurantium
and
C
.
sinensis
. Narirutin
naringin
hesperidin and neohesperidin showed good linear relationships within the ranges of 5.47-2 735 ng (
r
=0.999 6)
7.25-3 625 ng (
r
=0.999 5)
8.41-4 205 ng (
r
=0.999 4) and 8.36-4 180 ng (
r
=0.999 5)
and their average recoveries were 101.3% (
n
=6
RSD 2.9%)
98.0% (
n
=6
RSD 1.8%)
95.9% (
n
=6
RSD 0.8%) and 96.0% (
n
=6
RSD 1.1%)
respectively. The contents of narirutin
naringin
hesperidin
neohesperidin and total flavonoids were 0.36-1.28
2.66-4.87
1.02-11.07
3.58-6.41
and 7.98-13.34 mg·g
-1
respectively.
Conclusion:
2
The developed method was simple
accurate and reliable
which can be used to identify the source of Aurantii Immaturus Fructus and simultaneously determine the content of four flavonoids in Niuhuang Qingwei pills. It could provide basic research for quality control and composition comparison of 2 kinds of Niuhuang Qingwei pills
showing more comprehensive indicators and reference value for the quality standard improvement of Niuhuang Qingwei pill.
