Abstract
The compostion of the oils from flower and leaf of Achillea mellifolium L. subsp. mellifolium were collected during the flowering priod from Lar area to Damavand montain, altitude 3400 m in July 2003. The essential oils obtained by different methods of distillation (steam distillation and hydro-distillation), the percentage of oils for flower and leaf by steam distillation were 0.2 and 0.05% and by hydro-distillation were 0.4 and 0.04% respectively, based on the dry weight calculation. Analysis by GC and GC/MS showed that the major constituents by hydro-distillation in flower were p-cymene (19.8%), n-heptanol (15.2%) and bornyl acetate (12%) in leaf p-cymene (24.1%), n-heptanol (11.1%) and camphor (5.9%) and by steam distillation in flower were (E)-isoeugenyl acetate (18%), n-heptanol (16.3%), bornyl acetate (16.2%) and p-cymene (9.3%) in leaf (Z)- isodemicin (16%), (E)-isoeugenyl acetate (14.9%), nootkatin (13%) and longifolene (11.8%), respectively.
