| Abstract: | Objective To establish an HPLC method for the determination of quercetin in Jiangzhining Film-Coated Tablets.Methods Venusil MP C18（5 ？m,4.6 mm×250 mm） column was used for the HPLC determination,and the mobile phase consisted of methanol-0.2% phosphoric（55∶45） at a flow rate of 1.0 mL/min.The detection wavelength was 360 nm.Results Quercetin had good linear relationship in the range of 0.030 5-0.244 ？g（Y=97 709X-10 957,r2=0.999 8,n=5）.The average recovery was 100.08%,RSD was 1.64%.Conclusion The method is rapid and suitable for determination of quercetin in Jiangzhining Film-Coated Tablets. |
