Abstract

Nodosin, isolated from the flowers of Cassia nodosa, has been quantitatively determined in micro amounts by oxidizing with chlorauric acid in presence of alkali. The reaction is completed at 20 equivalence resulting in the formation of sodium formate and acetaldehyde. Maximum error was 0.6 %. The method is accurate and capable of giving reproducible results.
