Simultaneous Determination of Six Main Active Ingredients in Jiawei Xiangru Oral Liquid by HPLC
Objective: To establish a method for simultaneously determining the contents of puerarin
thymol
carvacrol
honokiol
hesperidin and daidzin in Jiawei Xiangru oral liquid (Puerariae Lobatae Radix
Moslae Herba
Magnoliae Officinalis Cortex
Citri Reticulatae Pericarpium
Bombyx Mori Linnacus and Lablab Semen Alabum). Method: High performance liquid chromatography (HPLC) was performed on Hypersil C18 chromatographic column (4.6 mm×250 mm
5 μm) with mobile phase of acetonitrile-0.01% glacial acetic acid (gradient elution) at a flow rate of 1 mL · min-1.The detction wavelength was 277 nm
and the column temperature was 30℃. Result: Puerarin
thymol
carvacrol
honokiol
hesperidin and daidzin showed good linear relationship between injection volume and peak area within the range of 0.384-4.800 μg (r=0.999 3)
0.048-0.600 μg (r=0.999 7)
0.015 6-0.195 0 μg (r=0.999 8)
0.018 2-0.227 5 μg (r=0.999 2)
0.226-2.825 μg (r=0.999 6)
and 0.228-2.850 μg (r=0.999 5)
respectively.The average recovery rate was 97.98%
98.88%
98.10%
100.12%
100.40% and 96.70%
respectively for puerarin
thymol
carvacrol
honokiol
hesperidin and daidzin
with RSDs of 2.1%
1.8%
2.1%
1.5%
2.6%
and 1.6%. Conclusion: The method is simple
stable and reproducible
and it can be used for the simultaneous determination of puerarin
thymol
carvacrol
honokiol
hesperidin and daidzin contents in Jiawei Xiangru oral liquid.
