Kinetin was previously assumed to be an unnatural and synthetic compound, until in 1996 Barciszewski et al. detected it in freshly extracted cellular DNA from human cells and in plant cell extracts And recently, Ge et al. identified kinetin and kinetin riboside from coconut water Being one of the cytokinins, kinetin has the effects on the plant developmental processes that could be influenced by cytokinins, such as leaf expansion and seed germination. Most importantly, kinetin is well known for its ability to retard senescence in plants
