title: Essential oils from stem and leaves of Angelica urumiensis (Mozaffarian) from Iran.
abstract: The composition of essential oils of the leaves and stem of Angelica urumiensis were analysed by chromatography-mass spectrometry. Overall, 58 volatile components were identified on the basis of their mass spectra characteristics and retention indices. Twenty-seven compounds were identified in the oil of the leaves, comprising 94.69% of the total oil, in which alpha-cadinol (20.2%), palmitic acid (14.14%), hexahydrofarnesyl acetone (10.03%), 1-dodecanol (7.55%), linoleic acid (6.37%) and oleic acid (5.34%) were the major constituents. Oxygenated sesquiterpenes and fatty acids were the main groups of compounds with 30.7% and 25.85%, respectively. Fifty compounds, representing 96.35% of the total oil, were identified in the stem oil. Palmitic acid (13.37), alpha-cadinol (9.24%), (epi)-alpha-cadinol (5.76%) and delta-cadenine (6.11%) were the major compounds. Sesquiterpenes and oxygenated sesquiterpenes dominated in the oil, comprising 28.03% and 20.9%, respectively. The chemical compounds of the essential oils showed that there are only 22 common compounds between two parts.
