title: Structural changes of zeatin during Acid hydrolysis.
abstract: Acid hydrolysis of zeatin under reflux at 100°C for 3.5 hours resulted in the formation of two compounds which were active in the soybean callus bioassay. One of these compounds was identified as 6-(3,4-dihydroxy-3-methyl-butylamino)purine. Available evidence suggests that this compound is not likely to be formed when endogenous cytokinins are fractionated with a cation exchange resin such as Dowex 50 at ambient temperatures.
