title: A cytokinin glucoside from the leaves of Phaseolus vulgaris L.
abstract: Phaseolus vulgaris plants decapitated above the primary leaves accumulate high cytokinin activity. The major cytokinin in these leaves was identified by Sephadex LH 20 chromatography, sensitivity to β-glucosidase and permanganate oxidation, and by combined gas chromatography-mass spectrometry as 6-(4-O-β-D-glucosyl-3-methylbutylamino) purine, (dihydrozeatin-O-β-D-glucoside). A possible reason for the persistance of this compound in the primary leaves is discussed.
