Objective:To develop a high performance liquid chromatographic method for simultaneous determination of myricetin and quercetin in Rose roxburghii. Method: The optimized method was achieved for the separation and detection of myricetin and quercetin using Zorbax SB-C18 (4.6 mm×150 mm
5 μm) as the stationary phase
methanol-0.4% aqueous phosphoric acid solution (65:35) as the mobile phase at a flow rate of 1.0 mL·min-1
368 nm as the detection wavelength. Result: Myricetin and quercetin showed good relationship in the range of 0.036 2-0.253 7 μg and 0.056-0.196 μg
respectively. The average recoveries of myricetin and quercetin were 98.32% and 98.84% with relative standard derivation (RSD) of 2.18% and 1.78%. Conclusion: The results showed that the method is simple
accurate and repeatable and it is suitable for quality control of R. roxburghii.
