| Abstract: | OBJECTIVE To develop a method for determination of ephedrine hydrochloride in nasal drops. METHOD Select the better method by comparing acid base titration with polarimetry.RESULTS The polarimetry was more suitable to analysis of ephedrine hydrochloride. The assay was linear over the range of 2.5 20mg/mL( r =0.99998). The average recovery was 100.8% with the RSD =0.054%.CONCLUSION The polarimetry is simple, rapid and accurate, which can be used for quantitative analysis of 0.5% ephedrine hydrochloride nasal drops. |
