A novel ultraviolet spectrophotometric method for the assay of microgram amounts (1-80 μg/ml) of CAT and CAB in aqueous solution has been developed. The method is highly sensitive, simple, and rapid within the limits of the experimental conditions described. The present method is also applicable for the determination of these two compounds present in a mixture since they have identical λmax and nearly the same ξmmax. The ultraviolet spectra of the compounds have been presented and the values of λmax and ξax are reported.
