| Abstract: | OBJECTIVE To determinate the related substances in ephedrine hydrochloride by HPLC. METHODS A Hypersil C6H5 column was used with the mobile phase of methanol-11.6 g·L-1 ammonium acetate solution (6:94, pH 4.0, adjusted with glacial acetic acid)at the detection wavelength of 257 nm. RESULTS Under the condition of selection, the ephedrine hydrochloride was separated from its related substances. CONCLUSION This method is simple, the speciality is excellent in the determination of the related substance. |
