We describe a method for accurately and precisely measuring dehydroascorbic acid in perchloric acid extracts prepared from human plasma, lymphocytes, and mammalian cells. Samples were assayed by spectrophotometrically monitoring the kinetics of the concentration-dependent absorbance changes of dehyd

It has been established that the antibiotic pefloxacin (Abaktal) methanesulphonate reacts with Fe(III) at pH 1.00-8.00 to form a water-soluble complex with maximum absorbance at 360 nm. The composition of the complex, determined spectrophotometrically by the application of Job's, molar-ratio and Ben
