The nitration of tryptophane by means of nitric acid in various concentrations has been studied. A polarographic method for the determination of tryptophane after nitration by heating on the waterbath for two hours with 3‐m. nitric acid has been established. The method gives a precision of 3% for concentrations of about 10 −4 ‐m.
