Essential Oil Composition of<i>Achillea eriophora, A. nobilis, A. biebersteinii</i>and<i>A. wilhelmsii</i>from Iran

Abstract

Abstract The major composition of the essential oils of these species from aerial parts growing wild in Iran analysed by GC and GC-MS. The essential oil of Achillea eriophora DC. were identified and major compounds were camphor (30.40 %), 1,8 cineol (25.24 %) and camphene (6.21 %). The essential oil of A. nobilis L. subsp neilreichii (Kerner) Formanek was found to contain: α-thujone (34.06 %), 1,8-cineole (14.14 %) and β-cedren epoxide (9.63 %) as the major constituents. The major compounds of A. biebersteinii Afan. were 1,8-cineole (32.82 %), carvacrol (10.85 %) piperitone (7.34 %). The oil of A. wilhelmsii C. Koch. was characterized by higher amounts of camphor (19.66 %), 1,8 cineole (9.06 %) and α-pinene (10.00 %). The results showed that 1,8-cineole in all species is major compound.
