Investigating the chemical composition of flower and leaf essential oil Achillea pachycephala Rech. F.

Abstract

The yarrow genus in Iran has 19 species of perennial and often aromatic herbaceous plants, seven of which are unique to Iran. In this research, the yarrow species with the scientific name Achillea pachycephala Rech. F. It was collected from Damavand peak at an altitude of 3200 to 3800 meters in the beginning of Shahrivar month of 2013. The sample was extracted by water distillation method. The yield of essential oil in flowers was 1.3% and in leaves was 0.5%. The samples were analyzed by gas chromatography (GC) and gas chromatography connected to mass spectrometer (GC/MS). The major compounds in the flower were trans-pinocarveol (29.2%), limonene (18.2%), myrtenyl acetate (17%) and pinocarvone (11.1%), which totaled 75.5% of 99.9% of the total It includes essential oil, and camphor (33.8 percent), 1,8-cineole (24 percent) and pinocampheol (16 percent) were found in the leaf, which was 73.8 percent out of 99.3 percent of the total essential oil. At the same time, the percentage of identified compounds is of special importance in relation to the species of this genus
