| Abstract: | Objective To determine the content of main compinents in ephedrine hydrochloride by RP HPLC. Methods The chromatographic separation was performed on Shim-pack VP-ODS C18 column with column temperature at 30℃. The mobile phase consisted of water （0. 1 % triethylamine, pH adjusted to 2.5 with formic acid） -methanol （90 ： 10） at 1.0 mL·min^-1. The detection wavelength was 200 nm and the sample size was 20 μL. Results The linear range of ephedrine hydrochloride was 1. 026 - 12. 825μg· mL^-1 （r = 0. 999 9）. The lowest detection limit was 513 ng · mL^-1. The average recovery was 98.88% （RSD = 1.33%）. Conclusion The method is simple, rapid, accurate and reliable, and suitable for the quality control of ephedrine hydrochloride. |
