Essential oil variation of Achillea filipendulinapopulations in farm condition

ABSTRACTAchillea filipendulinais a native aromatic plant with antibacterial and anti-inflammatory properties. This research aimed to determine and compare the essential oil content and composition of different populations of this plant in farm condition. Seeds provided by the Natural Resources Gene Bank of Iran were sown in a field experiment over two years. Essential oils from the aerial parts of all populations, at full flowering stage, were obtained by hydro-distillation and analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). The oil yields ranged from 0.13% to 1.20%. Twenty-six compounds were identified with 1,8-cineole (2.0–73.5%), santolina alcohol (14.2–35%) and borneol (0.6–20.4%) as major components. Cluster analysis divided all accessions into two clusters. The main compounds in cluster 1 (two populations) were santolina alcohol, borneol, cis-chrysanthenyl acetate, bornyl acetate and α-pinene. The oils in Cluster 2 contained borneol, cis-chrysanthenyl acetate and high amount of 1,8-cineole (22.6–73.5%) as main components.
