| Abstract: | Objective：To establish RP-HPLC method for the determnation related substances of midazolam syrup. Method： The separation was performed on Hypersil ODS C18 column （250mm ×4.6mm, 5 μ m）. The mobile phase consisted of methanol-0. 0672% ammonium acetate （60： 40） with a flow rate of 1.0ml/min. The detection wavelength was at 254nm. Results： A satisfactory separation condition among midazolam and the related impurities was obtained. The detection limit of midazolam syrup was 0.08ng. Conclusions： The method was sensitive, specificity and rapid, which can be used for determination of related substances of midazolam syrap. |
