Institute of Materia Medica, Chinese Academy of Medical Sciences, Beijing 100050

Received Date: 29 December 1989

A method is developed for the simultaneous determination of ephedrine,pseudoephedrine,norephedrine,norpseudoephedrine and methylephedrine in urine on a capillary column using nitrogen-phosphorus detector.Diphenylamine is used as the internal standard.Calibration graphs are linear down to 1.30ug/ml urine.
