| Abstract: | OBJECTIVE To establish an HPLC method for determination of quercetin in Fufang Luobuma Tablets by HPLC.METHODS Kromasil C18 column(250mm×4.6mm,5μm)was used,and acetonitrile-0.5% phosphoric acid(27∶73) was used as the mobile phase,detection wavelength was 371nm,the flow rate was 1.0 mL·min-1,and the column temperature was 30℃.RESULTS Quercetin showed a good linearity in the range of 0.9630～0.0803μg·mL-1,r=0.9998(n=7),and the average recoveries of quercetin were 99.46%.CONCLUSION The method criterion was sample and accurate,and the results of determination were satisfactory. |
