Methods Chromatography was carried out on a Dikma DiamonsilTM ODS column, using a mobile phase of methanol-water （55：45） with a flow rate at 1.0 mL·min^-1. The detection wavelength was 258 nm. Results Under the chromatographic condition, the peaks of 1-phenylpropanol and its related impurities separated completely; noninterference between the principal agent and adjuvants in preparations was performed. The calibration curve was linear over the range of 250 - 750μg·mL^-1 with the correlation coefficient of 0. 999 9. The average recovery was 100.2% （ RSD = 1.35% ）. Conclusion This method is simple, rapid, accurate, specific, and can be used to detect the content and related compounds of phenylpropanol in its raw material and preparations.展开更多
