Objective: For improving the quality level of Zhisou Qingguo pill
the qualitative and quantitative method for controlling the quality of Zhisou Qingguo pills was established.Method: Thin-layer chromatography was used for identifying the Fructus Terminaliae Immaturus which was developed with toluene-ethyl acetate-formic acid(5∶ 4∶ 1)
and ephedra developed with chloroform-methanol-strong ammonia(20∶ 5∶ 0.5);HPLC method was used for quantitative analysis with Acetonitrile-0.1% phosphoric acid solution [5∶ 95(containing 0.1% triethylamine)] as mobile phase
the flow rate was 0.8 mL·min-1 flow rate
detection wavelength was at 210 nm and column temperature was at 350 ℃.Result: Fructus Terminaliae Immaturus and ephedra were clearly detected in Thin-layer chromatography atlas;Linear relationship was set up(r =0.999 8) within 0.085-0.427 2 μg as the sample size of Ephedrine hydrochloride;The average recovery was 95.88%;RSD was 1.17%.Conclusion: The method was exclusive
accurate
and simple
and it can be used for the quality control of Zhisou Qingguo pills.
