Antimicrobial Activity of the Crude Ethanolic Extract of Carrichtera annua DC. Collected from Sinai, Egypt

Abstract

Carrichtera annua a plant belonging to family Brassicaceae was evaluated for the antimicrobial activity against a number of microorganisms. The powdered plant was extracted with ethanol. The concentrated ethanol extract was tested against a number of fungi, gram positive and gram-negative bacteria. The results revealed that the extract showed a significant and promising activity towards Aspergillus fumigatus, Proteus vulgaris, Enterococcus faecalis and Staphylococcus aureus with inhibition zones equal 17, 15, 13 and 11 mm. respectively. Additionally, the minimum inhibitory concentration (MIC) was determined and illustrated that, the most susceptible organisms to C. annua were Aspergillus fumigatus and Proteus vulgaris with MIC of 2.5 mg/mL and 5 mg/mL respectively. Therefore, C. annua could be considered as a promising source for effective antimicrobial agent.
