Essential Oil Composition of Leutea kurdistanica (Mozaff.) at the Vegetative and Flowering Stages

Abstract Leutea kurdistanica Mozaff. from Apiaceae family is an endemic herb growing wild in Iran. The essential oil variability of a population of L. kurdistanica at different phenological stages, namely the vegetative and flowering stages was studied for the first time by GC-FID and GC-MS. A total of 26 components were identified at the vegetative and flowering stages representing 98.5 and 99.3 % (w/w) of the oil, respectively. The ranges of major constituents were as follow: α-asarone (50.5-62.5 %), elemicin (16.4-22.5 %), α-phellandrene (1.3-5.9 %) and α-pinene (1.6-5.4 %). α-Asarone can be used for a wide range of applications in pharmaceutical and food industries.
