摘要：

A method is described for the determination of tryptophan in which it reacts with cerium(IV) in 0.15 M sulphuric acid. The method is rapid and precise and solutions can be analysed at a rate of 211 h(-1) with a relative standard deviation of ca. 0.45% at 12.5 mu g ml(-1) and a limit of detection of 0.1 mu g ml(-1). The effect of some common amino acids and monosaccharides which may be present along with tryptophan in tissue or protein hydrolysates has been investigated.
