ABSTRACT
The chemical composition of the essential oil produced by hydrodistillation from the fruits of Ammodaucus leucotrichus subsp. leucotrichus Cosson & Durieu collected from southern Algeria, precisely in Aougrout District (Adrar Province), was determined by GC-MS analysis. Nineteen (19) compounds, representing 85.71% of the essential oil, were found. The essential oil contained a high percentage of perillaldehyde (80.69%). This composition is compared to numerous reported essential oils of A. leucotrichus subsp. leucotrichus fruits that are found across Algeria and Morocco in various regions. The major component perillaldehyde has drawn a lot of interest in recent years due to its notable antifungal and broader antimicrobial properties, as well as its potential advantages for human health. Thus, the studied plant represents a source of this component that should be used as food additives, perfume ingredients, and in formulations of traditional medicine.
