In vitro antifungal properties of Pistacia atlantica and olive extracts on different fungal species.

OBJECTIVE

Pistacia atlantica, which belongs to the Anacardiaceae family, grows in the Zagrossian region of Iran. The aim of this study was to evaluate the antifungal properties of Pistacia atlantica and olive leaf extracts against different fungal species.

METHODS

In this study, we assessed the activities of olive leaf extracts and Pistacia atlantica leaf and fruit extracts against Candida species, including C. albicans, C. glabrata, C. tropicalis, and C. krusei. In addition, antifungal activities against three filamentous species, i.e., Aspergillus niger, Aspergillus flavus, and Aspergillus fumigates, were assessed, using the agar-well diffusion method.

RESULTS

The minimal inhibitory concentrations (MICs) values of fruit and leaf extracts from Pistacia atlantica ranged 6.25-12.5 mg ml-1 and 6.25-25 mg ml-1 against the tested Candida and Aspergillus species, respectively. The olive leaf extracts showed no activity against Candida species or Aspergillus flavus, while they exhibited antifungal potency against Aspergillus niger and Aspergillus fumigatus (MIC: 12.5-25 mg/ml). The MICs of the mixture of selected extracts ranged from 6.25 to 25 mg/ml.

CONCLUSIONS

Based on the results, the ethanolic extracts of the selected plants exhibited antifungal potency against the tested fungi and could be used as natural antifungal agents.
