Seventeen compounds representing 96.6% of the flower oil of A. schahrudensis were identified; among them, germacrene D (47.6%) and germacrene B (17.8%) were the major ones. The stem oil was characterized by higher amount of β-selinene(29.4%),δ-guaiene (21.7%), α-guaiene (13.4%) and α-selinene (10.9%) among the 14 components comprising 94.6% of the total oil detected. Eighteen compounds representing 97.3% of the leaf oil of the plant were identified; among them, α-pinene (33.8%) bornyl acetate (14.2%), limonene (12.2%) and α-fenchyl acetate (10.0%) were the major ones. The flower and stem oils of A.schahrudensis consisted mainly of sesquiterpenes, while in leaf oil monoterpenes predominated over sesquiterpenes.
