BACKGROUND
The plants of the Asteraceae family have been used for medicinal purposes,in traditional Colombian medicine.
OBJECTIVE
To evaluate the antifungal activity and the cytotoxic effects of 15 essential oils from plants of the Asteraceae family.
METHODS
Antifungal activity was evaluated against Candida parapsilosis ATCC 22019, Candida krusei ATCC 6258, Aspergillus flavus ATCC 204304 and Aspergillus fumigatus ATCC 204305 following EUCAST and CLSI M38-A standard methods, for yeast and filamentous fungi, respectively. Cytotoxic effect was evaluated on Vero cell line by MTT assay.
RESULTS
The oils from the plants Achyrocline alata and Baccharislatifolia were the only ones active against A. fumigatus (GM-MIC=78.7 and 157.4 microg/ml, respectively). In contrast, there was no evidence of oils active against Candida species. In addition, these oils were not cytotoxic on Vero cells. The oils of A. alata and Baccharis latifolia could be candidates for disinfecting hospital environments and for inhibiting biofilm formation by A. fumigatus
CONCLUSIONS
The oils of A. alata and B. latifolia could be candidates for disinfecting hospital environments and for inhibiting biofilm formation by A. fumigatus.
