Abstract: Objective: Ergosterin as the effective constituent was studied for the quality evaluation and providing a reference to the quality standard of Shengjing capsule. Methods:Chromatography:the chromatographic column was Agilent ZORBAX Eclipse XDB-C18,4.6 mm×250 mm,5 μm. The mobile phase was acetonitrile and water (92∶8),the flow rate was 1.0 mL·min-1,the detection wavelength was 283 nm,and the column temperature was 40 ℃. Results: After measuring the content of ergosterin and methodological research, it was found that ergosterin had a good linear relationship within the range of 2.589 7 μg·mL-1 to 25.896 5 μg·mL-1 (r=0.999 5), and the average recovery rate was 98.77% (RSD=0.78%). Conclusion: The experimental method was simple and accurate with good feasibility. It provided a reference for improving the quality standard of Shengjing capsule and could be applied to the quality control of Shengjing capsule.
