The present invention provides a process for the determination of cyanamide in plants or plant parts, wherein (a) the cyanamide is extracted from the plants, (b) it is subsequently reacted in aqueous alkaline medium with 1,2-naphthoquinone-4-sulphonate to give 4-cyanimido-1,2-naphthoquinone, (c) this reaction product is separated by high performance liquid chromatography on a reverse phase and (d) it is determined spectrophotometrically at a wavelength of 485 nm or 272 nm. |
