Antifungal activity of essential oil from Artemisia campestris L on fungal species development

Khaldi A, Meddah B and Moussaoui A

This work studies the antifungal capacity of the essential oil of spontaneous aromatic plant with vocation medication used in the traditional treatments in the South-West of Algeria: Artemisia campestris L. The local plant which was tested gave good essential oil yield (0.37%). The physico-chemical analysis of the essential oil of this plant species has enabled us to even characterize to identify our oil. Antifungal activity of the essential oil was studied witch respect to seven fungal strains with various concentrations. The results of direct contact method show that the oil of Artemisia campestris L is proven very effective on the mycelial growth of the moulds. All strains were inhibited at concentration as weak as 1/70 (v/v), Fusarium oxysporum f.sp. albedinis and Penicilluim expansum were most sensitive, being inhibited as from 1/800 (v/v) and 1/500 (v/v) respectively. This essential oil has a fungistatic effect. In addition to the growth of the mycelium, the essential oil of plant showed, in vitro, an antifungal activity at least important on the two other developmental stages, germination and the sporulation, of all fungi . All strains were inhibited at concentration as weak as 1/100 (v/v). Fusarium oxysporum f.sp. albedinis was most sensitive, being inhibited as from 1/1500 (v/v).
