Objective: To establish a method for simultaneously determining caffeic acid
quercetin-3-O-glucoside
kaempferol-3-O-glucoside and kaempferol in Geum aleppicum by RP-HPLC. Method: The quantitative analysis of G. aleppicum was carried out on Agilent C18 column(4.6 mm×250 mm
5 μm)
mobile phase was acetonitrile-0.5% formic acid with gradient elution
flow rate was 0.8 mL ·min-1
columntemperature was maintained at 25 ℃
and detection wavelengrt was 340 nm. Result: The linear relationships of caffeic acid
quercetin-3-O-glucoside
kaempferol-3-O-glucoside and kaempferol fell within the ranges of 0.045-1.130
0.095-2.370
0.105-2.635
0.041-1.030 μg
respectively. Their average recoveries (n=6) were 99.0%
98.5%
97.7%
100.7% with the relative standard deviations (RSDs) of 1.0%
0.9%
1.0%
1.6%
respectively. Conclusion: This method is simple
accurate
sensitive
which can be used for quality control of G. aleppicum.
