Abstract: Four extract amounts (200, 150, 100 and 50 mg mL-1) from twelve medicinal plant species that belong to six genera (Achillea, Salvia, Convolvulus, Plantago, Anthemis and Artemisia) were tested against Candida albicans. The antimicrobial activity was carried out by using the hole-plate diffusion method. The effect of plant species, extract amounts and their interaction were highly significant. Achillea santolina, Salvia dominica and Salvia officinalis inhibited the growth of Candida albicans at all tested extract amounts. The extracts of (Salvia spinosa, Convolvulus althaeoides and Plantago lanceolata) showed no activity against Candida albicans.
