AbstractThe extracts of five invasive plants were investigated for antifungal and antibiofilm activities against Candida albicans, C. glabrata, C. krusei, and C. parapsilosis. The antifungal activity was evaluated using the microdilution assay and the antibiofilm effect by measurement of the metabolic activity. Ethanol and ethanol‐water extracts of Reynoutria japonica leaves inhibited 50 % of planktonic cells at 250 μg mL−1 and 15.6 μg mL−1, respectively. Ethanol and ethanol‐water extracts of Baccharis halimifolia inhibited >75 % of the mature biofilm of C. albicans at 500 μg mL−1. The essential oil (EO) of B. halimifolia leaves was the most active (50 % inhibition (IC50) at 4 and 74 μg mL−1against the maturation phase and 24 h old‐biofilms of C. albicans, respectively). Oxygenated sesquiterpenes were the primary contents in this EO (62.02 %), with β‐caryophyllene oxide as the major component (37 %). Aromadendrene oxide‐(2), β‐caryophyllene oxide, and (±)‐β‐pinene displayed significant activities against the maturation phase (IC50=9–310 μ mol l−1) and preformed 24 h‐biofilm (IC50=38–630 μ mol l−1) of C. albicans with very low cytotoxicity for the first two compounds. C. albicans remained the most susceptible species to this EO and its components. This study highlighted for the first time the antibiofilm potential of B. halimifolia, its EO and some of its components.
