چکیده
This study reports the essential oil composition and antioxidant activity of the essential oil extract of aerial parts of Achillea Wilhelmsii. GC/MS analysis identified thirty compounds representing 94.48% of the oil. The main components comprising 86.99% of the oil were α-thujene (6.11%), α-pinene (5.11%), sabinene (5.23%), p-cymene (7%), 1,8-cineole (6%), linalool(10%), camphor (8.43%), thymol (18.98%) and carvacrol (20.13%). The samples were screened for their antioxidant activities using 2,2-diphenyl-1picrylhydrazyl (DPPH) radical assay methods. Thymol (13.0± 0.1 μg/ml) and carvacrol (15± 0.0 μg/ml) showed appreciable antioxidant activity in DPPH test.
