Abstract

The first order derivative UV spectrophotometry was for determination of ephedrine hydrochloride in its nasal drops to eliminate interference of ethyl p-hydroxyhenzoate.A good linearity has shown in the concentration of 5～25μg/ml,r=0.9999(n=5).The average recovery was 99.83% and cv was 0.49%.The method is simple,rapid and accurate.
