High perillaldehyde content from essential oils of subsp Cosson & Durieu fruits from Aougrout (Algeria).

The chemical composition of the essential oil produced by hydrodistillation from the fruits of subsp. 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 subsp. 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.
