Abstract

In order to introduce the biological effects of substances of plant origin on humans, especially wild plants on the soil of Croatia with regard to genus Satureja L. (S. montana L. and S. subspicata Vis.) and Eryngium L. ( E. alpinum L. and E. amethystinum L.), the aim of this study was to determine the spectrum of antimicrobial effects of methanol extracts of plant species with microdilution method (to determine minimal inhibitory concentration- MIC), and to investigate whether some extracts inhibited the germination of blastospores of Candida albicans. Extracts of S. montana showed the best antimicrobial activity against Staphylococcus aureus and Candida albicans (MIC=3,6 μg/ml), and S. subspicata Vis. against C. krusei (MIC= 10,9 μg/ml). There are significant differences in the activity within extracts from various locations where plants were collected. Extracts of E. alpinum affect on C. dubliniensis with MIC=13,7 μg/ml, as well as E. amethystinum. Extracts of Satureja L. showed significantly inhibitory effect on germination of blastospores of C. albicans more then 37% in concentration 30 μg/ml, and species of genus Eryngium L. in concentration 300 μg/ml 36%.
