[Cytokinins in Helianthus annuus].

Planta, 2014
With two extraction procedures differing in the very first extraction steps two cytokinins from a total amount of 180 kg sunflower leaves could be isolated. One of these cytokinins is identified as zeatin by Rf values, UV absorption, melting point of its picrate and its biological activity. The same data are given for the other cytokinin, which is very
