The effect of prepared constituent in colonmetric determination of aminopropylon with ninhydrin Analysis of aminopropylon. II

The authors have reported in the previous papers (Analysis of aminopropylon. I.) the spectrophotometricassay of aminopropylon. The method was not satisfactory in removing interferences by noscapine (J.P.), phenacetin (J.P.) and acetaminophene. In order to remove these interferences, and to determine...

Summary:The authors have reported in the previous papers (Analysis of aminopropylon. I.) the spectrophotometricassay of aminopropylon. The method was not satisfactory in removing interferences by noscapine (J.P.), phenacetin (J.P.) and acetaminophene. In order to remove these interferences, and to determine the aminopropylon existing with antifebrile, anodyne, antihistamine etc., the authors adopted a method with 0.1N HCl-chloroform extract treatment whereby most of them were extracted into chloroform and aminopropylon remained in 0.1N HCl layer. Aminopropylon in antifebrile, anodyne, antihistaminne etc. was determined with good accuracy.
