Application of potassium ferricyanide method for the estimation of carbohydrate in cane leaves

Abstract

1. A method for the quick estimation of carbohydrates in cane leaves is described and it consists in the direct use of lead oxlate filtrate for the titration of glucose with 1% alkaline potassium ferricyanide solution. 2. This method is shown to be simpler, quicker and more economical than the standard methods of Bertrand and Schaffer and Hartmann. 3. The three methods are shown to give excellent comparable results for glucose in cane leaves while the new method gives the least observational error thus adding to the precision of results.
