Abstract

 

The objective of the present work is to identify the chemical composition and to test the antioxidant activity of the essential oils of Perralderia coronopifolia Cosson subsp. Purpurascens (Asteraceae) collected in the oasis of Tata located in south east of Morocco. The essential oils was obtained by hydrodistillation method and analyzed by GC-MS. Antioxydant activity was tested using DPPH (2, 2-diphenyl-1-picrilhydrazyl) assay. A total de 27 compounds were identified representing 83.59 % of the essential oils. The main compounds were γ-eudesmol (24.4%), α-eudesmol (19.77) and cis-nerolidol (13.97). antioxidant DPPH assay revealed an IC50=3.81 mg/mL. Constituents and antioxidant activity of the aerial part of the Perralderia coronopifolia Cosson subsp. Purpurascens were reported for the first time to our knowledge.
