    • Abstract

       

      A method for the estimation of tannin in presence of catechin, pyrogallol, protocatechuic acid and gallic acid using polyamide column chromatography was developed. Tannin added to the growing culture ofAspergillus flavus was oxidised to different extents depending on the duration of incubation. The oxidised compound was identified in the culture filtrate as a polymerised product of tannin.
