Antimicrobial activities of Six Types of Wheat Bran

Abstract

Six types of wheat bran (Emam, Pohean, Wadielneel, Argeen, Pladi and Debeira) investigated for their biological and antioxidant activities. Physiochemical properties carried for their oil. The polar and nonpolar extracts showed antioxidant activity. These results showed the importance of the wheat bran types as nutritive and medicinal plant. All plant bran types investigated for its biological activity as antifungal and antibacterial. Some types of the plant bran extracts showed antibacterial activity towards Escherichia coli, Pseudomonasaeruginosa, Bacillus subtilis, and Staphylococcus aureus. In addition, some types of the extracts showed antifungal activity towards Candida albicans, and Aspergillusniger. Polar and nonpolar extracts of the plant bran types prepared. The petroleum ether extracts subjected to determination by GC/ MS. It showed different major fatty acids as Linoleic acid followed by Linolelaidic acid and then Palmatic acid. The ethanolic extract of Plaid type separated by column chromatography. The isolated constituents were structurally determined using spectrophotometric analysis as IR, UV, and GC/MS. The ethanolic extract components may be esters and ketones as suggested by GC/MS and their functional groups appeared in the IR readings.
