| Abstract: | Objective To establish a method of spectrophotametry for determining the concentration of Dexamethasone sodium phosphate and Ephedrine hydrocholoride in nasal drops.Methods New Vierordt's method was used without separation.The determination wavelength were 242nm and 256nm.Results The average recovery of Dexamethasone sodium phosphate was 99.59% and RSD was 0.62%. The average recovery of Ephedrine hydrochloride was 100.17% and RSD was 0.14%.Conlusion This method is simple,quick and accurate. |
