Objective: The study was conducted to establish an HPLC method for the determination of quercetin and naringenin in the moxa flavone cream. Method: Quercetin and naringenin were separated on Gemini C18 RP-column(4.6 mm×250 mm
5 μm)
the flow rate was 1.0 mL· min-1
column temperature was 25℃
and the detection wavelength was 330 nm
the injection volume was 10 μL
with 0.5% aqueous acetic acid as the mobile phase A was and acetonitrile as B for gradient elution. Result: Quercetin and naringenin showed good linear relationship in the range of 0.010 26 to 0.307 8 μg (r=0.999 9)
0.009 87 to 0.296 1 μg (r=1) respectively.Their average recovery rates were 97.32% with RSD of 3.3% and 97.22% with RSD of 2.7%
respectively. Conclusion: The method is simple
rapid
reproducible
and it can be used for the quality of control moxa flavone cream.
