ABSTRACT
Objective:
To improve the quality standard for Qingyuantiaozhi capsules.Methods:
The main components of the prep-aration, such as Chrysanthemum, Anthraquinones, Hawthorn and Radix Rehmanniae Preparata, were identified by TLC qualitatively. The content of chlorogenic acid in chrysanthemum was determined by HPLC. A DIKMA Spursil C18(250 ×4.6 mm,5 μm)column was used with methanol-0. 2% phosphoric acid solution(9 ∶91) as the mobile phase. The flow rate was 1. 0 ml·min-1, the detection wavelength was set at 327 mn and the sample size was 20 μl.Results:
The spots in TLC were clear without any interference. The cali-bration curve was linear within the range of 4. 425 2-30. 976 4μg·ml-1(r=0. 999 9) for chlorogenic acid. The average recovery was 101. 18% (RSD=1. 88%, n=6).Conclusion:
The improved quality standard is specific, accurate and reproducible, which can be used for the quality control of Qingyuantiaozhi capsules.
