Chemical composition of the essential oils of Astrodaucus persicus (Boiss.) Drude root, stem/leaves and flowers/fruits

The essential oils of Astrodaucus persicus (Boiss.) Drude were obtained by hydrodistillation of root and aerial parts and examined by GC and GC-MS. The composition of oil samples was compared; 22, 20 and 14 compounds were identified in the essential oils of the root, stem/leaves and flowers/fruits, representing 94.4%, 99.7% and 99.9%, respectively, of the total oils. The major components were bornyl acetate (26.5%), beta-sesquiphellandrene (25.9%) and exo-fenchyl acetate (25.1%) for the root oil, a-pinene (56.4%) and exo-fenchyl acetate (37.7%) for the stem/leaves oil and beta-pinene (46.1%), alpha-pinene (26.1%) and alpha-thujene (14.4%) for the flowers/fruits oil. The highest amount of sesquiterpenes was found in the root oil (30.7%). Copyright (c) 2005 John Wiley & Sons, Ltd.
