Popis: The fractionation and properties of the polyphenolic compounds of the Egyptian sorghum grains were studied. The results showed that sorghum grains contained a higher amount of non-tannin polyphenols than tannin ones. By utilizing the funnel separation technique higher recovery for both tannin and non-tannin polyphenol fractions was given compared with the Sephadex LH 20 column chromatography method. The refractionation of both fractions using T.L.C. technique showed that each fraction of tannin and non tannin composed of different compounds differed in their properties.
