Brassica oleracea var. Italica: A Nutritional Supplement with Antimicrobial Potential

Abstract

Two compounds were isolated from the ethyl acetate extract of Brassica oleracea var. Italica (Brassicaceae), which were obtained from successive extraction of broccoli florets. They were nitrogenous compounds, identified by spectroscopic analysis as uridine and uridine 9-acetate. Ethyl acetate and chloroform extracts were found to be effective against Bacillus cereus and Bacillus subtilis, respectively, gram-positive bacteria. Ethyl acetate and ethanol extracts were highly active against E. coli (gram-negative). Additionally, ethyl acetate and chloroform extracts showed high activity against Candida albicans.
