czs-Zeatin riboside was isolated and identified as its trimethylsilyl derivative from tubers of sweet potato by solvent extraction, ion-exchange chromatography, high performance liquid chromatography, Amaranthus betacyanin bioassay, and mass spectrometry. The level was estimated from the result of bioassays.
The presence of ribosyl trans-zeatin was determined in sweet potato tubers by means of solvent extraction, ionexchange chromatography, high performance liquid chromatography, Amaranthus betacyanin bioassay, and mass spectrometry. The level was estimated to be 1.32^g/kg fresh weight of the tuber.In previous papers, we have reported the presence and level of cis-RZ1] and IPG2) in sweet potato tubers. We have now found the presence of trans-RZ by means of GC-MS, HPLC, and the Amaranthus betacyanin bioassay froman extract of the tubers. In this communication, we wish to report the isolation and identification of trans-RZ from sweet potato tubers, as well as the levels of other cytokinins found in the tubers.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
