Abstract
Abstract Dihydrocodeinone is separated from pheniramine and similar antihistamines by passage of a chloroform extract of the combined bases over a chromatographic column on which 2N HCl is the stationary phase. The latter is retained on the column while the dihydrocodeinone passes through. The dihydrocodeinone is transferred from the chloroform eluate by shaking it with a measured volume of sulfuric acid, and the concentration is measured spectrophotometrically. The method is recommended for adoption as official, first action.
