Summary

Using ethyl acetate extraction in a liquid-liquid extractor three cell division inducing compounds, that coelute with authentic cytokinins, were extracted from sprouting potato tubers. The major peak of activity coeluted and cochromatographed with zeatin riboside. In the low resolution mass spectrometer the active substance yieldedm/e peaks characteristic of N-6- substituted adenines.
