Abstract
Codeine has been separated from a mixture of codeine, morphine and nalorphine on Whatman ET20 ion-exchange paper, in 5 min. A mixture of morphine and nalorphine has been separated in 90 min. by horizontal circular reversed phase paper chromatography. Using ascending chromatography at 86° on tributyrin-treated paper, an unequivocal resolution of a mixture of morphine, nalorphine and codeine has been achieved within 20 min.
