Sorghum grains contain phenolic compounds that have been shown to have many favourable effects. In this study the levels of phenolic compounds in condensed tannin and condensed tannin-free sorghums have been determined and the antimicrobial activity of phenolic extracts from bran fractions of the respective sorghums has been further evaluated against pathogenic bacteria Bacillus cereus ATCC 1178, Escherichia coli ATCC 25922 and Listeria monocytogenes ATCC 7644.
