Chemical characterization of essential oil of Artemisia herba-alba asso and his possible potential against covid-19

Abstract

In this work, we studied the chemical composition of the essential oil obtained by hydrodistillation from the aerial parts of Artemisia herba-alba Asso growing wild in Tafingoult in Morocco. The oil yield was 0,71% based on dry weight. Chemical analysis by GC / MS identified twenty-five constituents representing 98.43% of the essential oil. Chrysanthenone (39.67%) was the main component of A. Herba-alba Asso. Moreover, a high content of oxygenated monoterpenes characterizes this essential oil. This suggests that it has biological activities, namely antiviral activities of at least one of its constituents. Hence the idea of proposing the plant for scientific research as a potential source of antiviral molecules against COVID-19.
