| Abstract: | Objective To establish the analytical method of ephydrochlorico in Xiaoer Zhike Mixture.Methods Soaked by pH 5.8 phosphate buffer solution,complexes formed by ephedrine hydrochloride and brompthymole comle were extracted and determined at the wavelength of 420 nm.Results The linear equation was Y=0.008713x+0.05024,(r=0.9995),the average recovery of ephedrine,hydrochloride was 98.8%(RSD=1.83%).Conclusions The method is simple,accurate and can be used to control the quality of Xiaoer Zhike Mixture. |
| Keywords: | Xiaoer Zhike Mixture ephedrine hydrochloride acid dye spectroplotometry |
