| Abstract: | A new cytokinin was isolated from methanol extracts of immature lupin seeds (Lupinus luteus) through successive purification of charcoal adsorptions, silver precipitations, ion exchange and paper chromatography. The structure was confirmed by spectral data and synthesis as (?)-6-N-(4-hydroxy-3-methylbutylamino)purine, (?)-dihydrozeatin (I). |
