Notes:
A procedure has been developed for the synthesis of 6-chloropurine labelled with four 15N atoms. This compound can be used in the synthesis of a range of labelled cytokinin bases, which can be ribosylated by an enzymatic procedure. 15N labelled zeatin riboside was synthesized and used as an internal standard in the measurement by selected ion monitoring of the levels of this cytokinin in cultured crown gall and normal tissues of Vinca rosea, which were found to contain 402 and 2.5 ng per g fresh weight respectively.
