The labelled natural cytokinins can be distinguished in the MS analysis because the m/z values of their mass spectral fragments are displaced by several mass units (m/z > 2 amu). A known quantity of the labelled cytokinin is added to the initial extract, and after purification the molar ratio of natural cytokinin to labelled internal standard is determined by mass spectrometry. The quantitative analysis by MS was first carried out by Thompson et al., Planta, 124: 207, 1975.
