| Abstract: | A HPLC method was established for the determination of Imperatorin in Tongqiaobiyan Tablet. The samples were extracted by supersonic with methanol. RP-HPLC analysis was carried out on Thermo Hypersil-Keystone ODS C18 column and the mixture of Methanol-Water （70： 30） was used as the mobile phase,the detection wavelength at 300 nm,the column temperature at 25℃ and the flow rate at 0.8mL· min^-1. The standard curve was linear over the range of 0.02 - 0.20μg, and the average recovery was 100.26% with RSD 1.41%. The method is sensitive, accurate and specific. It may be used for the quantitative determination of Imperatorin in Tongqiaobiyan Tablet. |
