Antifungal properties of propolis

Abstract

Water extracts at the concentration of 0.5, 1, 2, 3 and 4%, of propolis were prepared and investigated for inhibition of Altemaria alternate, Aspergillus niger, Aspergillus parasiticus, Botrytis cinerea, Fusarium oxysporum f.sp. melonis and Penicillium digitatum in culture media. The concentration of 4% was the most inhibitory of 5 concentrations studied. Microorganisms the most effected from all the concentrations among tested fungi were Alternaria alternata and Penicillium digitatum. The concentration of 4% of propolis extract showed more than 50% inhibition against all tested microorganisms.
