Carboxyatractyloside was labeled with [3H]KBH4 after oxidation of the primary alcohol of the glucose disulfate moiety by dicyclohexylcarbodiimide and P2O5 under anhydrous conditions in a dimethylsulfoxide medium. The 3H-labeled product was purified by DE 52 column chromatography followed by Cellulofine
