| Abstract: | Aim To develop a method for determining the contents of quercetin in Sijicao capsules. Methods The analytical column was a hypersil ODS2 5 um（4.6 mm × 250mm）. The mobile phase consisted of methano-0. 4% phosphoric acid aqueous solution（50： 50）. The flow rate was 1.0 mL ·min^- 1. The detection wavelength of quercetin was at 360 nm. Results The calibration curves of quereetin was in good linearity over the range of 2.27 - 20.44 mg · L^-1, and the average recovery was 100.21%. Conclusion The method is simple, rapid, reliable and can be used for the drug control. |
