Abstract

Four propolis samples of Czech and one of Slovak origin were extracted using Soxhlet apparatus and analysed by thin-layer chromatography. Raw propolis samples and their extracts were tested by microdilution broth method to determine minimal inhibitory concentration (MIC) in eight strains of human pathogenic fungi.

Raw propolis samples showed a lower in vitro antifungal activity than their extracts. In general, the petroleum ether extracts exhibited the highest in vitro antifungal activity (MIC range of 16-64 mu g/ml).

The content of flavonoids in the samples varied according to region. The highest amount of flavonoids was found in sample A that originated from Broumov (4%).

The most susceptible to the propolis extracts were Trichophyton mentagrophytes and Candida albicans.
