Quantification of cytokinin O-glucosides by negative ion mass spectrometry

Pulsed positive ion-negative ion chemical ionization mass spectra of O-glucosyl-zeatin and -dihydrozeatin, their ribosides, and their N-9 2-cyanoethyl and 2-chloro-2-cyanoethyl derivatives are reported. By methods based on these spectra, the levels of the glucosides were determined in soybean (Glyci...

Zusammenfassung:	Pulsed positive ion-negative ion chemical ionization mass spectra of O-glucosyl-zeatin and -dihydrozeatin, their ribosides, and their N-9 2-cyanoethyl and 2-chloro-2-cyanoethyl derivatives are reported. By methods based on these spectra, the levels of the glucosides were determined in soybean (Glycine max) leaves.
