Mass spectrometry using selected ion monitoring, high-performance liquid chromatography and an Amaranthus betacyanin bioassay enabled six endogenous cytokinins to be identified from potato (Solanum tuberosum L. cv. Danshaku) tubers, and their levels to be determined. 9-β-D-Glucopyranosyl 6-(3-niethyl-2-butenylamino)purine, a new glucopyranosyl derivative of i6 Ade, was found from the tubers.
