[Abstract] Objective: To establish the determination method for determining the content of hesperidin in combined stomach oral liquid. Methods: The high-performance liquid chromatography (HPLC) method was used to determine the content of hesperidin in the studied product. The Octadecylsilyl (ODS) column was 250 mm×4.6 mm×5 μm; the methanol-2% acetic acid solution (39∶61) presented mobile phase; the flow rate was 1 ml/min; the detection wavelength was 283 nm. Results: Hesperidin showed a linear relationship in the content of 0.134 4 to 1.680 0 μg, r=0.999 8. The sample recovery rate was 98.44%, RSD=1.21% (n=6). Conclusion: This method is sensitive, accurate and reproducible, and therefore can be used as one of the quality control indicators of combined stomach oral liquid.
