Uses of Eucalyptus camaldulensis Dehnh (Myrtaceae) in the City of Korhogo and in Vitro Evaluation of the Antifungal Activity of its Essential Oil by Microatmosphere on Two Fungi Found in Stored Foodstuffs

The objective of this study was to explore the antifungal activity of Eucalyptus camaldulensis essential oil against phytopathogenic fungi in stored foodstuffs. To this end, an ethnobotanical survey was conducted in the city of Korhogo on the uses of Eucalyptus camaldulensis. Next, the essential oil was extracted from Eucalyptus camaldulensis leaves by hydrodistillation, followed by an exploration of the in vitro antifungal activity of its essential oil. The ethnobotanical survey was conducted on 24 households in the city of Korhogo. A total of 72 people were interviewed. The survey revealed that the leaves of Eucalyptus camaldulensis are the most commonly used parts of the plant (50%), followed by the bark (29.16%). The antifungal power of E. camaldulensis, tested using the microatmosphere method on agar medium against fungal strains of Aspergillus niger and Botryodiplodia sp, revealed fungistatic activity at respective quantities of 25, 40, 60, and 80 µL of E. camaldulensis essential oil. The inhibitory effect of E. camaldulensis oil suggests potential applications in the preservation of certain foodstuffs.
