Extraction of essential oils and evaluation of the biological activities of Artemisia herba alba.Asso and Artemisia campestris L in the Tiaret region

Abstract

The objective of this study is to evaluate the antioxidant activity and antifungal activity of the essential oils extracted from the aerial part of the medicinal plants of the family of asteraceae: Artemisia herba alba Asso «chih» and Artemisia campesiris L «Dgouft» harvested in the region of Ain Deheb (Tiaret).The extraction of essential oils and hydrolat from the aerial part of the plants studied was carried out by the method of hydrodistillation with a yield of 0.25% and 0.73% respectively. The antioxidant activity of the essential oils of both plants is evaluated by the iron reduction method (FRAP test), shows a low activity of 0.031% of Artemisia herba alba.Asso and 0.041% of Artemisia compestris L, above all in relation to the percentages obtained from the standards used of 0.96% for gallic acid and 0.42% for ascorbic acid. The antifungal effect of both essential oils was evaluated by the direct contact method (fungistatic or fungicide). The essential oils of Artemisia herba alba.Asso, Artemisia compestris L have a weak antifungal and antioxidant effect.
