| Abstract: | Glucose, fructose, xylose, arabinose, and sucrose have been determined titrimetrically using manganese(III) sulfate as an oxidant. On reaction in the dark, glucose consumes 5, fructose 7, xylose and arabinose 6 each, and sucrose after hydrolysis 12 equivalents of Mn(III) per mole, respectively. Sucrose has also been estimated following other methods and the results have been compared. Two leaf sample extracts are analyzed for the determination of reducing sugar and total reducing matter and the results are compared with those obtained by the other method. |
